Concrete Mix Ratio And Their Tpyes - 2020 Guide

Nominal Concrete Mix Ratios Previously the specification for concrete was proportion of Cement, Sand and Course Aggregates. The fixed ratio of these was to ensure the strength to the structure. Nominal concrete mix are low grade concrete mixes which are used for small and unimportant works.

Types of Concrete Mix Ratio Design and their Strengths ...

Nov 15, 2011  These mixes of fixed cement-aggregate ratio which ensures adequate strength are termed nominal mixes. Nominal mixes offer simplicity and under normal circumstances, have a margin of strength above that specified. However, due to the variability of mix ingredients the nominal concrete for a given workability varies widely in strength.
