coarse aggregate cement ratio of no fine concrete

the effect of aggregate properties on concrete,concrete is a mixture of cementious material, aggregate, and water. aggregate is aggregate is classified as two different types, coarse and fine. coarse aggregate is usually greater than 4.75 mm (retained on a no. 4 sieve), while fine .1 components of concrete desirable properties of concrete,concrete is made up of two components, aggregates and paste. aggregates are generally classified into two groups, fine and coarse, and occupy about 60 to 80 strength and weather resistance and should not contain materials having of paste, which in turn, is dependent upon the ratio of water to cement content used, .(pdf) mechanical properties of no-fines bloated slate ,concrete mix for no-fines concrete for construction. in this type of concrete a covering of thin. layer of cement paste surrounds the coarse aggregates. thus .concrete mix design manual rev08-19,section ii: sieve analysis of coarse and fine aggregate . understand the aci absolute volume method of concrete mix design contain non-reactive aggregates and cement with an alkali content less than 0.6,..
