5 Stages at RMC Plant for Quality Concrete

Demonstrating technical rigor, automation, and material science in concrete production.

Stage 1: Raw Material Sourcing & Moisture Compensation

Raw Material Sourcing & Moisture Compensation: Testing & Calibration.

– Aggregate Grading: Coarse aggregates (10mm & 20mm) and fine aggregates (Zone II sand/M-sand) undergo daily sieve analysis (IS 2386).

– Moisture Moisture Sensors: Sand moisture is continuously measured using microwave moisture probes inside the plant bin to adjust added water automatically in real-time, maintaining an exact Water-Cement (W/C) ratio.

Stage 2: Micro-Processor Controlled Batching

Precision Weighing (±1% Tolerance)

– Load-Cell Weighing: Cement (OPC 53 Grade), mineral admixtures (Fly Ash/Silica Fume), and aggregates are weighed independently using high-precision digital load cells under IS 4926 guidelines.

– Liquid Admixture Dosing: Third-generation Polycarboxylate Ether (PCE) superplasticizers are dosed down to fractional liters for optimal flowability without segregation.

Stage 3: Twin-Shaft High-Intensity Homogeneous Mixing

Forced Mechanical Blending

– Forced Mixing: Raw ingredients enter an automated twin-shaft mixer.

– 30 to 45-Second Cycle: The high-shear mixing action breaks up cement agglomerates, coating aggregates evenly with cementitious paste, critical for high-strength grades like M65, M85, and M100.

Stage 4: Automated Slump & Temperature Verification

Pre-Dispatch Quality Check

– Slump Inspection: A sample is taken at the discharge chute to confirm target slump (typically 120mm – 150mm for pumpable concrete).

– Thermal Control: During peak NCR summer heat, batch water is chilled or replaced with micro-ice flakes to maintain concrete discharge temperature below 30°C (preventing thermal cracking).

Stage 5: Transit Mixer Loading & Hydration Retardation

Controlled Transit

– Drum Loading & Rotation: Concrete is discharged into transit mixer drums rotating at agitating speed (2–4 RPM).

– Hydration Management: Dosing is calibrated according to target travel time to prevent early setting while maintaining pumpability upon site arrival.
