Read MoreConcrete mix ratio is a vital topic in concrete mix design. the four basic ingredients for making concrete are portland cement, sand, aggregate stone and water. the strength of concrete mixture depends on the ratio in which these four ingredients are mixed.
Read MoreExcess reducing of cement content or increase of sand content will adversely affect the strength of concrete. hence it is advisable not to increase the fine aggregate river sand and m sand content more than 30 above the prescribed ratio in any case.
Read MoreContent also has adverse effect of the strength of concrete due to poor adhesion. researchers have therefore develop various models for predicting the effect of sand fines and wc on the strength of concrete. however, there is a gap in literature for the combined effect of sand fines and watercement ratios effect on the properties of concrete.

Read MoreIn order to consider the additional water for easy concrete placing, the samples with higher wc ratio, and constant cement content are prepared through adding mix water. surface saturated condition of sand is prepared for this mixing and finally 4 different mix proportions are considered as wc of 0.45, 0.50, 0.55, and 0.60.
Read MorePaste needed to make concrete using the aggregate. for instance, sand with a low fineness modulus has more voids in it and more particle surface, thus, more paste is needed to fill voids and cement the particles together than would be needed for a coarser sand. below is an example of the mechanical sieve analysis results of a fine and coarse
