crushed rocks such as granite, basalt, sandstone, slate, and limestone are common examples. The specific gravity of these aggregates is between 2.5 and 2.7. These aggregates are commonly used to manufacture concrete.
Slump, being property of fresh concrete-mix depends a lot on thewater-cement ratio. The ratio of mass of water to the mass of cement is termed as water-cement ratio. Civil engineers write it as “W/C”. The typical value is around 0.40 to 0.60. Workability and slump of concrete is d...
