RA is a waste concrete-derived material created by two-stage grinding and processing and eliminating contaminant substances, including reinforcements, woods, and plastic rubble. While the longevities of buildings can be greatly enhanced by prolonging their useful lives, they must be demolished and ...
Finer grinding may be used for improving pozzolanic activity. In the present study, SS with a particle size of 75 µm possesses moderate pozzolanic activity, suitable to be used as SCM's. Influence of sewage sludge on slump flow The slump flow values of freshly mixed concrete mix are ...

There is a tendency for some fine aggregates to degrade from the grinding action in a concrete mixer. This effect may alter mixing water, air-entraining admixtures, and slump requirements. Coal or lignite, or other low-density materials such as wood or fibrous materials, in excessive amounts,...

the standard sand must pass through a 2 mm IS sieve completely and remain on a 90 micron IS sieve, demonstrating the particle size distribution outlined in Table6. Moreover, as per IS 383:2016, seashore gravels and seashore sand are naturally rounded in shape. The permissible limits of harm...
Fig. 19. Embodied carbon of concrete floor systems per m2 of covered plan area. Further significant carbon saving can be achieved by transitioning into a more efficient industrialised process. By optimising the following variables, a reduction of 27% from the baseline is possible: These procedures...
