Factor Affecting Concrete Mix Design Of Concrete

factors affecting permeability of concrete - civil snapshot,there are several factors which influence the durability such as water to cement ratio, concrete compaction, concrete curing, and age of concrete. so, such factors shall be taken into consideration during mix design and construction of concrete structure. factors influencing concrete permeability. there are three major factors that influence the permeability of concrete: 1. water to.drying shrinkage of cement and concrete,internal factors the internal factors affecting drying shrinkage of concrete are those related to its constituents: cements, aggregates, admixtures; concrete mix design; water-cement ratio and water content; aggregate properties and volume fraction; and those related to the construction of the concrete: placing, compaction and curing..
