Nominal Mixes In the past the specifications for concrete prescribed the proportions of cement, fine and coarse aggregates. These mixes of fixed cement-aggregate ratio which ensures adequate strength are termed nominal mixes. These offer simplicity and under normal circumstances, have a margin of strength above that specified.
Concrete admixture. Mid-range water reducers – These admixtures provide superior placeability and finishing for concrete flatwork, in commercial and high-end residential construciton. Air detraining agents – These liquid air-detraining admixtures reduce the level of plastic air in non air-entrained concrete. michael.delros….
