AAC Block Manufacturing Process — Step by Step

  1. Raw Material Batching: Fly ash, cement, lime, gypsum, aluminium powder, and water are weighed by the SCADA Batching System and mixed into homogeneous slurry. India's first fully automatic SCADA batching delivers ±0.1% gravimetric accuracy per batch. See full SCADA Batching System specifications →
  2. Mould Filling & Pre-Curing: Slurry is poured into steel moulds. Aluminium reacts with lime to generate hydrogen gas, expanding the mix. Pre-curing 2–4 hours.
  3. Tilting & Demoulding: Hydraulically tilted 90° by the Tilting & Demoulding Machine, green cake separated onto cutting rack. See Tilting Machine specifications →
  4. Wire Cutting: The Wire Cutting Machine performs simultaneous horizontal and vertical cutting to ±1.5 mm block dimension tolerance. See Wire Cutting Machine specifications →
  5. Autoclave Curing: Cut blocks loaded into the Autoclave for 12 bar / 190 °C steam curing for 10–12 hours — permanent silicate bond formation. IBR-approved SAE 516 Gr 70 pressure vessels. See Autoclave specifications →
  6. Handling & Dispatch: Cured blocks are separated by the AAC Separator, then conveyed by the Finished Block Handling System, palletised, shrink-wrapped, and dispatched to sites. See Finished Block Handling System →

Frequently Asked Questions — AAC Block Plant

What is the capacity range of Maruti Hydraulics' AAC block plants?

Maruti Hydraulics manufactures AAC block plants from 150 CBM/day to 1200 CBM/day. Standard sizes are 150, 200, 300, 500, 800, and 1200 CBM/day. India's largest AAC plant at 1200 CBM/day was commissioned by Maruti Hydraulics in 2024.

Does Maruti Hydraulics provide turnkey AAC plant installation?

Yes. Maruti Hydraulics provides complete turnkey services: feasibility study, plant layout design, equipment manufacturing at the ISO-certified Nashik factory, installation, commissioning, 30-day on-site technology transfer, and long-term after-sales support including spare parts within 36 hours across India.

What is the cost of an AAC block plant in India?

AAC plant investment varies by capacity and site-specific requirements. Maruti Hydraulics provides detailed project reports (DPR) with capacity-matched equipment quotations. Contact +91-253-2308131 for a customised DPR.

Which IS standard applies to AAC blocks manufactured in India?

AAC blocks must comply with IS 2185 Part 3:2005 — Specification for Concrete Masonry Units: Autoclaved Cellular or Aerated Concrete Blocks. Key parameters: dry density 400–900 kg/m³, compressive strength ≥2 MPa (Grade D 500), moisture content ≤35%. Maruti Hydraulics' plants are configured to produce IS 2185-compliant blocks.

Can Maruti Hydraulics supply both the factory building and the AAC plant machinery?

Yes — Maruti Hydraulics designs and erects Pre-Engineered Buildings (PEB factory sheds up to 90 m clear span) and then equips the same building with the complete AAC block plant line under one contract. Single vendor, single project manager, zero coordination gaps between civil structure and machinery.

India's AAC Block Market — Why Now Is the Right Time to Invest

India's AAC block manufacturing sector is experiencing the strongest demand growth in its history, driven by five structural factors. First, the National Green Tribunal's ongoing orders restricting new red clay brick kilns near agricultural land across multiple states — affecting the dominant traditional building material and creating a supply gap that AAC blocks fill. Second, the ECBC (Energy Conservation Building Code) mandating thermal performance in commercial and government buildings across India, where AAC's 30–40% better insulation versus clay brick significantly reduces HVAC costs. Third, RERA (Real Estate Regulatory Authority) accountability requirements for construction quality and delivery timelines — pushing developers toward factory-manufactured, dimensionally consistent materials. Fourth, construction labour costs rising 9–12% annually since 2020, increasing demand for larger-format blocks that require less laying time per square metre of wall. Fifth, architectural specification shifts: a generation of Indian architects trained in green building design are now routinely specifying AAC blocks in residential and commercial projects as a standard specification choice, not a premium option.

The geographic expansion of AAC block adoption is also significant: five years ago, AAC block manufacturing was concentrated in Gujarat, Maharashtra, and Rajasthan. Today, new plants are being commissioned in Odisha, Chhattisgarh, Jharkhand, Assam, Kerala, and Tamil Nadu — states that had minimal AAC presence in 2019. Maruti Hydraulics has commissioned plants in most of these states and can provide reference plant visits for investors evaluating any of these markets.

AAC Block Manufacturing — Key Economics

For an investor evaluating AAC block manufacturing, the key economic parameters are: raw material cost (fly ash at near-zero cost under MOEFCC notification for plants near thermal power stations; cement, lime, gypsum, and aluminium powder at market rates); energy cost (steam for autoclaving is the largest operating cost, typically 18–25% of total manufacturing cost for coal-fired boilers); labour (15–25 workers for a 150–300 CBM/day plant, varying by automation level); block selling price (Rs 38–60 per unit for standard 600×200×200 mm Grade B600 blocks, varying by region and competition); and plant payback period (typically 3–5 years for a 150–300 CBM/day plant at standard market pricing and 80% capacity utilisation). Maruti Hydraulics prepares plant-specific financial projections as part of every project feasibility assessment.
