Concrete is a mixture of cement sand aggregate and water which hardens with time When we change the proportion of these components the strength of concrete changes accordingly Just take the case of building construction In buildings there are various structural elements—like footings columns beams slabs

The concept of replacement of natural fine aggregate by quarry dust which is highlighted in the study could boost the consumption of quarry dust generated from quarries By replacement of quarry dust the requirement of land fill area can be reduced and can also solve the problem of natural sand scarcity The availability of sand at low cost as a fine aggregate in concrete is

introduction:- in this topic we know about how to calculate quantity of cement in PCC and cement consumption in PCC 1:4:8 we know that we have several grade of concrete like M5 M7 5 M10 M15 M20 and M25 and so more— Generally PCC is stand for plain cement concrete which has a mix of cement sand and aggregate in fixed proportion
