Aggregate is commonly considered inert filler which accounts for 60 to 80 percent of the volume and 70 to 85 percent of the weight of concrete. Although aggregate is considered inert filler it is a necessary component that defines the concretes thermal and elastic properties and dimensional stability.
Strength of RCC is defined as compressive strength after 28 days expressed as M15 M20 where M stands for Mix and 15 stands for 15 Nmm 2 nmm 2 must be read as Newtons per millimeter Cubed compressive strength at 28 days. The proportions of materials cement sand coarse aggregate for nominal mixdesign mix concrete that are normally used are 136 or 148.

The apparent density or unit weight of an aggregate is the Mass or weight of the aggregate needed to fill a container with a specified unit volume. Density of aggregate in kgm3 - the approximate apparent density of the aggregate that is commonly used in normal-weight concrete work is between 1200-1750 kgm3 but for estimating purpose it .

Weight of aggregate required 1450 X 0.88 1276 Kgs. . As the units of Sand amp; Aggregate seem to be in Kgsm3 therefore multiplication with Bulk Density Kgsm3 the result will be unit less. . Tell me how if i need to calculate quantities of aggregate size 10 mm and 20 mm for 1 bag of cement and also the quantity of admixture. Hamza Ali.
The fine aggregate is natural sand that has been washed and sieved to remove particles larger than 5 mm and the coarse aggregate is a gravel that has been crushed washed and sieved so that the particles vary from 5 to 50 mm in size.The fine and coarse aggregate is delivered separately. As they need to be sieved a prepared mixture of fine and coarse aggregate is more expensive than the .
