referred to as green type concrete. Crushed demolition waste can be used for selfcompacting concrete [1]. Use of waste materials in concrete ... river sand was used as fine aggregate with fraction ... Indian Standards. The accuracy of the readings is verified by the average of three measurements.
This creates a close cohesion of sand particles and cement. In case of cement concrete the voids formed between sand and coarse aggregate gets filled with the paste forming a cohesive substance/concrete. The required quantity of water is used to prepare mortar or concrete, but in practice it is seen that more water is mixed to make the mix ...

The 40 is the compressive requirement of 40 N/mm² of a crushed 100m concrete core and the 50 is a compressive requirement of 50 N/mm² for a crushed concrete cube. Therefore using the method of testing using concrete cubes, the tested compressive strength should be compared to .
When structures made of concrete are demolished or renovated, concrete recycling is an increasingly common method of utilizing the rubble. Concrete was once routinely trucked to landfills for disposal, but recycling has a number of benefits that have made it a more attractive option in this age of greater environmental awareness, more environmental laws, and the desire to keep construction ...

Reinforced concrete (RC) (also called reinforced cement concrete or RCC) is a composite material in which concrete's relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel reinforcing bars and is usually embedded passively in the concrete before the ...
Material of particle size smaller than 0,125 mm. It will also include this size fraction of the sand. Selfcompacting concrete (SCC) Concrete that is able to flow under its own weight and completely fill the formwork, even in the presence of dense reinforcement, without the need of any vibration, whilst maintaining homogeneity.
