What are the requirements of RMC according to QC I?

This covers (i) materials storage, (ii) monitoring of quality of materials, (iii) modification of mix design, (iv) plant maintenance, (v) calibration of equipment and (vi) plant and transit mixer condition.

What are the quality tests on fresh concrete?

Fresh concrete tests measure factors such as strength, consistency, unit weight, air content, and temperature.

What is the quality control of concrete?

The quality of concrete is affected by different physical and mechanical properties of aggregate, i.e. shape, grading, durability, specific gravity and water absorption etc. these properties of aggregated should be tested before using it for concrete production.

What are the different tests for concrete?

Methods for Testing Compressive Strength of Concrete

• Rebound Hammer or Schmidt Hammer (ASTM C805)
• Penetration Resistance Test (ASTM C803)
• Ultrasonic Pulse Velocity (ASTM C597)
• Pullout Test (ASTM C900)
• Drilled Core (ASTM C42)
• Cast-in-place Cylinders (ASTM C873)
• Wireless Maturity Sensors (ASTM C1074)

Is code for ready mix concrete?

As per Indian Standard code of practice (IS 4926) Ready Mixed Concrete (RMC) is defined as the concrete delivered in tailor- made condition and requiring no further treatment before being placed in position in which it is to set and harden.

How can we control the quality of concrete?

As far as possible concrete should be batched by weight. If weight batching is not possible, then volume batching may be permitted through proper supervision in the presence of engineer in charge. During mixing the mixer should be charged to its full capacity. The materials should be fed in proper sequence.

How many types of aggregate test are there?
