Answer Posted / sjtbehera
ans- you told 300sqft and 12mm th. Ratio is 1:6
convert 300 sqft = 27.77 sqm
= .012x 27.77= .333cum
= .333+1/5x .333 = .399 this is done for 20%
increase in volume mortar for joints depression and wastage
= .399+1/3 x .399 = .532 cum this done when mortar
increase 1/3ed volume when dry.
Than calculating cement = .532/7 = .076 cum = 2.1 bags
where as 1 bag= .0347 cum
7 is the summation of 1:6 ratio
sand - .076 x 6 = .456 cum
