Concrete quality control - field note 084

During the 8‑week concrete pour for the Pune commercial complex, CEMEX India supplied 5000 m³ of pre‑mixed concrete. Pre‑mix slump tests revealed a 4 cm variance, prompting a mix redesign.

• Calibrate batching plants every 48 hrs.
• Perform on‑site slump and air‑content tests for each batch.
• Use a real‑time strength monitoring system.
• Document and review results in a daily log.

The redesign delivered a compressive strength boost of 25%, meeting the design requirement of 35 MPa.
