AS per IRC, A Design mix proportion was designed forthe normally popular M30 concrete for pavement construction in India. In this, Cement was replaced withpercentages (10, 20, 30 and 40%) of Class C fly ash and of coconut fibers (0.50 and 1.0 %) having 40 mmlength were used. Test ...
Volume of coarse and fine aggregate = 1 – 0.2791 = 0.7209 m3 Volume of F.A. = 0.7209 X 0.33 = 0.2379 m3(Assuming 33% by volume of total aggregate ) Volume of C.A. = 0.7209 – 0.2379 = 0.4830 m3 Therefore weight of F.A. = 0.2379 X 2.61 X 1000 = 620.919 kg/ m3 Say weight ...
Mix Proportion By weight = 1: 2.48: 3.31 –Aggregates should be used in saturated surface dry condition. If otherwise, when computing the requirement of mixing water, allowance shall be made for the free (surface) moisture contributed by the fine and coarse aggregates. On the other hand,...
These parameters were taken in such a way that the various combinations of these factors would yield optimum concrete mix in the practical range of compressive strength. Two grades of concrete i.e. M20 and M30 were obtained from experimental investigation. The experimental data were utilized to ...
