C. TEST DATA FOR MATERIAL:

12.5mm: 0.30%

D. MIX DESIGN CALCULATION

Water : 135 Kg/Cum.

Cement content : 270 Kg/Cum.

Free Water Cement Ratio : 0.50

Coarse Aggregates (%) : 60%

Fine Aggregates (%) : 40%

Coarse Agg Proportion (20mm) : 50%


Chemical Admixture : 1.2 Kg/Cum. Dosage :

a) Volume of Concrete

b) Volume of Cement = (Mass of Cement / Sp. Gr. of Cement) x (1 / 1000)

c) Volume of Water = (Mass of Water / Sp. Gr. of Water) x (1 / 1000)

d) Volume of Admixture = (Mass of Admixture / Sp. Gr. of Admixture) x (1 / 1000)

e) Volume of All in aggregates = {a - (b + c + d )}

f) Vol of Coarse Aggregate = e x Proportion of Coarse Agg

g) Vol of Fine Aggregate = e x Proportion of Fine Agg

h) Mass of 20mm Aggregate = f x Proportion of 20 mm xSp. Gr. of 20 mm x 1000

i) Mass of 12.5mm Aggregate = f x Proportion of 12.5 mm x Sp. Gr. of 12.5mm x 1000
