Temperature-controlled concrete for mass pours that demand discipline.
Engineered for raft foundations, transfer slabs, and continuous mass pours. Concrete temperature ≤25°C. Heat of hydration controlled. Continuous discharge for 4-8 hours.
Inside Alpha Mass
Alpha Mass solves the hardest problem in concrete: pouring 200, 500, or 1000 cubic meters in a single continuous session without thermal cracking or strength loss. Mass concrete generates heat as cement hydrates; uncontrolled, this heat creates thermal gradients that crack the structure. Alpha Mass eliminates this risk through engineered cooling, calibrated retarders, and SCM blends.
We pre-cool the concrete in three ways: chilled mixing water (10-15°C), partial replacement of mixing water with ice (up to 30%), and shaded aggregate stockpiles. The concrete leaves our plant at 22-24°C even on Bangalore's hottest summer days. Combined with high GGBS or fly ash replacement (40-60%), the heat of hydration is reduced by 30-40% compared to OPC concrete.
For pours exceeding 100 m³, we add a structural engineer-approved retarder dosage, extending workability to 120+ minutes. For pours exceeding 500 m³, we coordinate with multiple plants and provide dedicated dispatch teams. Alpha Mass brings world-class mass-pour capability to Bangalore.
Built for mass concrete pours
Chilled water (10-15°C), ice integration (up to 30% of mix water), and shaded aggregates ensure target temperature even at 38°C ambient.
40-60% SCM replacement (GGBS or fly ash). Lower cement clinker content. Engineered to reduce peak temperature in mass element by 30-40%.
Ice plant integration at our Ramohalli plant. Chilled water tanks at 10-15°C. Aggregate pre-cooling for critical pours.
Calibrated retarder dosage extends initial setting time to 6-8 hours. Single mass pour can extend to 8 hours without cold joints.
40-60% mineral admixture replacement. Lower heat, higher long-term strength, better durability. Approved SCM sources with MTCs.
Dedicated dispatch coordination. Multiple TMs scheduled at 8-12 minute intervals. Real-time tracking via BuildX Live (Q1 2027).
