### What is specific gravity of cement range QuoraStandard Specification for Chemical Admixtures for Concrete

Apr 06 32 The particle density of Portland cement ranges from 310 to 325 Mg/m³ averaging 315 Mg/m³ For mixture proportioning it may be more useful to express the density as relative density specific gravity On an average the specific gravity of cem Note 1 It is recommended that whenever practicable tests be made using the cement pozzolan aggregates air entraining admixture and the mixture proportions batching sequence and other physical conditions proposed for the specific work 114 because the specific effects produced by chemical admixtures may vary with the properties and proportions of the other ingredients of the concrete
