Dosage: Typical air entrainment ranges from 5% to 8% of the volume of concrete. Water reducers have become so important in concrete, that they could be considered the "fifth" ingredient. They can be used to: (1) increase slump, (2) lower the water-cement ratio, or (3) reduce cement content.
What is the ratio of admixture in concrete?
The percentages of Sikament-163, which are added in concrete mixture, are 0 % (normal concrete), 0.75 %, 1 %, 1.25 %, 1.5 %, 1.75 %, 2 % and 2.5 % by cement weight. The research is conducted using nine test specimens for each percentage of Sikament-163 with the same slump.
How is concrete admixture percentage calculated?
Calculation of Sand & Coarse Aggregate Quantities:
Admixture = 1.2 % by weight of cement = 5.064 kg.
