Assessment of CO2 Emissions by Replacing an Ordinary

emissions of the ordinary reinforced concrete slab and the void slab system were 204,433.06 and 151,754.75 kg CO2-eq, respectively, which equated to about 34% less emissions for the void slab system. In the case of the ordinary reinforced concrete slab, moulds accounted for approximately 62% of CO2 emission

Cement Consistency Test Standard Consistency of Cement

Standard Consistency of an ordinary Portland cement varies between 25-35%. That means we need 25% of water in volume to make a standard consistency of cement. For Example, If we need to calculate the amount of water required for a 200 g of cement which has 30% consistency means then we need 200*30% = 60g water to prepare a standard consistency.
