Table 3 shows the flow value of the mixtures containing BA. It shows that flow value for the BA blended cement mortars were decreased with increase in the percentage of BA. The control mix (BAM 0) has a flow value of 147 mm [30]. The flow value of mixes BAM 5, BAM 10, BAM 15, BAM 20, BAM 25, and BAM 30 shows decrease of 146, 146, 145, 144, 143, and 142 mm respectively. BA requires more water for proper consistency when compared to that of ordinary Portland cement due to irregular shape with rough surfaces, high porous texture and absorptive in nature [5]. Increase in water demand of BA, decreases the flow value and resulted in poor workability. W/C ratio was kept same as 0.5 for all mixes. The flow value of BAM 30 reduced to 3.4 % due to…
Ingredients for concrete are cement, fine aggregate, coarse aggregate and water. The best concrete can be obtained by mixing the ingredients in correct proportions. The ideal proportion of concrete will be that, which produces greatest strength and solidity at the least cost. In estimating the quantities of ingredients for cement concrete it should keep in mind that voids of coarse aggregates are filled up by sand and voids of fine aggregates are filled up by cement. The concrete mix of 1: 1: 2 and 1: 11/2: 3 are mostly used for water retaining structures. The concrete mix 1: 2: 4 is most commonly used for R.C.C. construction. The mix proportion of 1: 3: 6 and 1: 4: 8 are used in lean concrete works. The concept behind the proportioning of concrete mixes is that the resulting concrete is densest and strongest with least amount of cement. Following are the methods of proportioning concrete:…

In general, the increasing industrial activity and the rising cost of natural mineral resources, and forcing the ready mixed concrete industry to review the logistics of raw material supply. A lack of potable water, an integral constituent of concrete has resulted in search for possible alternatives. While almost any natural water that is drinkable and has no pronounced taste or odour may be used as mixing water for concrete, the rising cost of such water has prompted many researchers to experiment with salt water in concrete. The…
