Aggregate Crushing Strength Test

 · The crushing strength or aggregate crushing value of a given road aggregate is found out as per IS-2386 Part- 4. The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement aggregate possessing low aggregate crushing value should be preferred.

Lab 1 – Concrete Proportioning, Mixing, and Testing

If the slump is still less than required, return the concrete to the mixer, add additional water, as well as additional Portland cement to maintain the desired water/cement ratio (Wt. of PC added = Wt. of water added/WC ratio), and mix for one minute. Continue taking slump tests and adding water and cement until the desired slump is obtained.

Tests on Concrete

 · Procedure of slump test for concrete: Clean the cone. Dampen with water and place on the slump plate. The slump plate should be clean, firm, level and non-absorbent. Collect a sample of concrete to perform the slum test. Stand firmly on the footpieces and fill 1/3 the volume of the cone with the sample. Compact the concrete by ''rodding'' 25 times.

Penetration Resistance Test for Concrete Compressive Strength

Penetration resistance test rapidly and accurately determines the compressive strength of the concrete. The strength is found out by firing (shooting) a probe or pin on the surface of the concrete with the known amount of force. Penetration resistance test is a modern system to measure the compressive strength of hardened concrete.
