Mix Design and Pumped Concrete - Civil Engineering Portal

Note: When coarse and fine aggregate of different types are used, the free-water content is estimated by the expression 2/3 W f + 1/3 W c. where W f = free-water content appropriate to type of fine aggregate. and W c = free-water content appropriate to type of coarse aggregate. Table 5 Estimated wet density of fully compacted concrete, (kg/m3).

Concrete Rated Source Quality Catalog

Fine Aggregate = 880 . We know that total fines less than 0.25 mm for pumpable concrete should be 350 to 400 kg per cubic metre of concrete. As the fine aggregate passes 0.3 mm sieve is 19%, the sand particles passing through 0.25 mm sieve = 19 x 25/30 = 16% app. ∴ Fine particles in sand = [(16 x 880)/100] = 140.8 = 141 kg.
