lightweight concrete in hyderabad

Lightweight concrete is a type of ready-mix concrete that weighs less than normal concrete. Aparna RMC supplies EchelonCrete for applications where reducing dead load, improving insulation, or filling a space with a lighter material is required.

EchelonCrete is supplied as ready-mix concrete, and the density is selected based on the application. This guide explains lightweight concrete uses, density ranges, applications, quality checks, and what to consider before ordering lightweight concrete in Hyderabad.

Lightweight Concrete Or Lightweight Blocks? Which One Your Project Need

Lightweight concrete and lightweight blocks are not the same product. Lightweight concrete is mixed at a batching plant and delivered to the site in a transit mixer. It is then poured, pumped, or placed as required. Lightweight blocks such as AAC and CLC blocks are factory-made masonry units used mainly for walls. Aparna RMC supplies EchelonCrete lightweight ready-mix concrete, not lightweight blocks.

Lightweight ready-mix concrete Lightweight blocks
Supplied wet in a transit mixer Supplied as precast blocks
Placed by pouring, pumping or screeding Placed by masonry work
Used for screeds, filling, levelling and other suitable applications Used mainly for walls and partitions
Supplied by cubic metre Usually supplied by number of blocks or masonry volume
Aparna RMC supplies EchelonCrete Aparna RMC does not supply AAC or CLC blocks

For a project that needs walling blocks, a block manufacturer is required. For a project that needs LWC delivered to the site at a specified density, EchelonCrete is the relevant Aparna RMC product.

The four types of lightweight concrete

Lightweight concrete falls into four types: lightweight aggregate concrete, made with expanded clay, shale, or sintered fly ash aggregate; cellular or foam concrete, aerated with preformed stable foam; autoclaved aerated concrete, produced as precast blocks; and no-fines concrete, which omits fine aggregate. Only the first two are commonly supplied as ready-mix.

Type What it is Supplied as ready-mix?
Lightweight aggregate concrete (LWAC) Uses lightweight aggregates instead of conventional dense aggregates Yes, where specified
Cellular / foam concrete Uses preformed foam to create air voids in the cement-based mix Yes
Autoclaved aerated concrete (AAC) Aerated concrete produced as factory-made units No — mainly blocks and panels
No-fines concrete Uses coarse aggregate and cement without fine aggregate Rarely

Only some types are normally supplied as ready-mix. The detailed production methods and properties of these types are covered in the main lightweight concrete guide.

Density, Grade And Strength: How To Read A Lightweight Concrete Specification

Lightweight concrete is specified by density rather than by strength alone. IS 2185 (Part 4) sets density grades for preformed foam cellular concrete from 800 to 1,800 kg/m³, with average compressive strengths rising from 2.5 N/mm² at 800 kg/m³ to 25 N/mm² at 1,800 kg/m³. Normal-weight concrete is roughly 2,400 kg/m³.

EchelonCrete is available in different density ranges to suit the requirements of the application. The required density depends on the application and technical requirements.

Reference density and strength grades for preformed foam cellular concrete blocks

Density (kg/m³) Grade Average compressive strength (N/mm²) Typical use
800 G-2.5 2.5 Non-load-bearing
1,000 G-3.5 3.5 Non-load-bearing
1,200 G-6.5 6.5 Load-bearing
1,400 G-12 12.0 Load-bearing
1,600 G-17.5 17.5 Load-bearing
1,800 G-25 25.0 Load-bearing

Reference note: The table above presents density and strength grades referenced under IS 2185 (Part 4):2008 for preformed foam cellular concrete blocks. These values are provided as a general standards reference and are not EchelonCrete product specifications. EchelonCrete density, strength and mix requirements are selected and confirmed according to the specific project and application.

The final density is selected based on the project requirement. Aparna RMC’s technical team can recommend the suitable density after considering the application and structural requirements.

Where Lightweight Concrete Is Used On Hyderabad Projects?

Lightweight concrete can be used for terrace insulation and roof-slope screeds, sunken slab filling, void filling, floor levelling, and rooftop amenity build-ups. The density is selected based on the application, as each use has different requirements.

Application Why lightweight concrete is used
Terrace insulation / roof-slope screeds Helps reduce dead load and provides thermal insulation
Sunken slab filling Replaces heavier filling materials and reduces dead load
Void filling Fills spaces without adding the same weight as conventional materials
Floor levelling Provides a balance of strength and weight for levelling
Rooftop amenity build-ups Helps control the additional load from rooftop elements

The final EchelonCrete density, strength and mix are determined according to the application, project requirements and site conditions.

Terrace insulation and roof-slope screeds

Lower-density EchelonCrete can be used for terrace insulation and roof-slope screeds. It can help reduce the additional dead load on the roof slab while also providing better thermal insulation than a conventional dense screed.

The required slope and thickness should be decided as part of the overall roof design.

Sunken slab filling and void filling

Sunken slabs and other voids are often filled with materials that add considerable weight. LWC can be used in suitable applications to reduce this additional load.

EchelonCrete can be supplied at low-to-moderate densities for sunken slab filling and void filling. The final density depends on the required application and site conditions.

Floor levelling

Floor levelling may require a considerable quantity of material, especially when the difference in levels is large. Using moderate-density lightweight concrete can reduce the weight added to the floor compared with conventional dense materials.

EchelonCrete densities in the range of around 1,000–1,400 kg/m³ may be considered for floor levelling, depending on the required performance and project conditions.

Rooftop amenity build-ups

Rooftop gardens, pergolas and other amenity areas can add extra load to a roof. Lightweight concrete can help control the weight of the additional build-up.

For these applications, EchelonCrete can be supplied in higher density ranges of around 1,200–1,850 kg/m³, depending on the required strength and project conditions.

Why Lightweight Concrete Can Help Reduce Dead Load In Telangana?

Lightweight concrete reduces the weight added to a building compared with normal-weight concrete. In Hyderabad, the main reasons for using lightweight concrete include reducing dead load on slabs, columns and foundations and improving thermal performance in suitable terrace applications.

Dead load on foundations, columns and existing slabs

Every additional layer added to a building increases the dead load. This includes filling, screeds, levelling layers and rooftop build-ups.

Using a suitable lightweight concrete mix can reduce this additional load. This can be useful when working with existing slabs or when the project has limits on the load that can be added.

The required density should always be checked against the structural requirements of the project.

Thermal performance on terraces and top floors

Lower-density lightweight concrete contains more air voids, which can help reduce heat transfer. The thermal performance of EchelonCrete depends on the selected density and mix.

Lightweight Versus Normal-Weight Concrete

Lightweight concrete can reduce dead load and provide better thermal insulation, but it costs more than normal-weight concrete. It requires proper density control, suitable mix design, and careful handling during placement and pumping.

Factor Lightweight concrete Normal-weight concrete
Density Lower Higher
Dead load Reduced Higher
Thermal performance Generally better at lower densities Generally lower
Material cost Can be higher Generally lower
Density control Requires close control Standard control
Placement and pumping Requires more care More conventional
Water absorption Can be higher Generally lower
Site control Density needs to be checked Standard site controls

Advantages of EchelonCrete

Reduced dead load: Lightweight concrete weighs less than normal concrete, so it can reduce the load added by filling, screeds, and other suitable applications.

Thermal insulation: Lower-density mixes contain air voids that help reduce heat transfer. This makes them suitable for applications such as terrace insulation.

Different density options: EchelonCrete can be produced at different densities, allowing the mix to be selected according to the application.

How To Evaluate A Lightweight Concrete Supplier In Hyderabad?

Before choosing a lightweight concrete supplier, check how the supplier controls density, batching, testing, delivery, and technical support. These points are important because lightweight concrete needs closer control than a normal concrete mix.

1. Check density verification

Ask how the supplier checks the density of fresh concrete. Aparna RMC carries out wet-density checks as part of its quality-control process.

A calibrated container of fixed volume is used to check the fresh bulk density before the concrete is cast or pumped.

2. Check batching records

Aparna RMC uses an automated batching system. Each delivery is accompanied by a batch slip generated through the SCADA system.

The batch slip includes details such as the customer and project, batching and dispatch time, product identification, batch volume, ingredient quantities, and transit mixer number.

3. Check testing and documentation

Wet-density test records are maintained by the plant quality team. Batching records are also retained and can be compiled when required for project quality records, auditing or billing verification.

4. Check plant and delivery capability

Aparna RMC has a presence in several areas in Hyderabad, including Patancheru, Osmannagar, Tellapur (Osmannagar), Shamshabad, Peerzadiguda (Uppal), Bollaram, Kompally, Rajendranagar, Gandimaisamma, Gatkesar, Nallagandla, Kompally, Gundlapochampally, Puppalguda, Manikonda Jagir, Nanakramguda, and Gachibowli.

With these plans, Aparna RMC is supporting lightweight concrete supply for projects in and around Hyderabad.

EchelonCrete contains specialised ingredients and may require foam generators, lightweight aggregates, or special admixtures depending on the mix. Pours therefore need to be planned in advance with the plant team.

Aparna RMC has 36 automated batching plants, which can help coordinate supply for larger pours where the plant and logistics conditions allow.

5. Check technical support

The required density should not be selected only from a general product range. It should match the actual application.

Aparna RMC’s technical and R&D teams can work with structural engineers, architects and site teams to assess the application and recommend the required density and mix.

6. Volume Capability

Large or continuous EchelonCrete pours need to be planned with the plant team. Supply depends on plant logistics and the availability of specialised ingredients.

Where required, supply can be coordinated across nearby plants to support larger-volume pours.

Ordering Lightweight Concrete: Lead Time, Minimum Order, And What Arrives On Site

Order EchelonCrete based on the application, required density, quantity and site conditions. Discuss the pour with the plant team in advance, as specialised materials and production planning may be required.

Before ordering, confirm the density, quantity, pour date, pumping requirement, site access and placement conditions.

Each delivery includes an automated batch slip with project and dispatch details, product identification, batch volume, constituent quantities and transit mixer number.

Aparna RMC supplies lightweight concrete across Greater Hyderabad with a minimum order of 10 cubic metres. Each delivery arrives with a batch slip recording mix, density, and volume. Site access, pump position, and placement readiness should be confirmed before the delivery window is booked.
