H.W. #1 27 Nov. 2021 Q.I A Convert the mix ratio of concrete (1: 2: 3.5/ 0.55) by weight to the mix ratio by volume. Sp.Gr. of cement = 3.0, Agg. =2.5 Q.2 Total absolute volume of concrete mix is 2.37, and the % volume of water in the mix is 19%. Find the w/e ratio of this mix (by weight). Q.3 Is the % volume of aggregate ingredients in the concrete mix is (10% sand : 12% gravel) correct or Not? If Not, what is approximately the natural % volume of aggregate in the mix? Q.4 Which mix is the Rich mix by cement? Why? 1. [10% cement: 15% water: 30% sand: 45% Gravel] (by volume) 2. [18% cement: 24% water: 28% sand: 30% Gravel] (by volume)

Q.1 A Convert the mix ratio of concrete (1: 2: 3.5/ 0.55) by weight to the mix ratio by
volume. Sp.Gr. of cement = 3.0, Agg. =2.5
Q.2 Total absolute volume of concrete mix is 2.37, and the % volume of water in the mix
is 19%. Find the w/c ratio of this mix (by weight).
Q.3 Is the % volume of aggregate ingredients in the concrete mix is (10% sand : 12%
gravel) correct or Not? If Not, what is approximately the natural % volume of aggregate
in the mix?
0.4 Which mix is the Rich mix by cement? Why?
1. [10% cement: 15% water: 30% sand: 45% Gravel] (by volume)
