Concrete Mix Ratios Cement Sand Aggregate And Water
concrete mix ratio is a vital topic in concrete mix design. the four basic ingredients for making concrete are: portland cement, sand, aggregate and water. the strength of concrete mixture depends on the ratio in which these four ingredients are mixed.the flexural strength of concrete was found to be to 11% of the compressive strength of concrete of higher strength concrete of the order of mpa and to 12.8% for concrete of strength less than mpa see table 13. the ratio of flexural strength to compressive strength was found higher for mm maximum size aggregate than that of mm max sized aggregate.jun 01, 2006 the percentage of total reinforcement ranged from 0.98 to 4.71. the concrete consisted of ordinary portland cement, natural pit sand and crushed granitic rock of mm maximum size. the mix proportions by weight, properties of concrete at days, and of reinforcing babadua bars are presented in table table twelve slabs were tested at age
