The following formula is used to find the quantity of coarse aggregate in 1m 3 of concrete Volume of Aggregate Aggregate CementSandAggregate x 157 Density of aggregate may go higher if void spaces decreases 5mm aggregate has more density when compared with 20mm size of aggregate Hence We require 1326Kg of 20mm aggregate for 1m 3 of
Coarse aggregate means the aggregate which is retained on 4.75mm sieve when it is sieved through 4.75mm. To find fineness modulus of coarse aggregate we need sieve sizes of 80mm, 40mm, 20mm, 10mm, 4.75mm, 2.36mm, 1.18mm, 0.6mm, 0.3mm and 0.15mm. Fineness modulus is the number at which the average size of particle is known when we counted from ...

Cement density- generally density of cement is around 1440kgm3 or it is measured in other unit- their density is 1.440 in gcm3, 94 in lbft3 and 14.40 in knm3. The cement mixed with fine aggregate produces cement mortar for masonry, or with sand and gravel produces concrete. Ans. 1440 kgm3 is density of cement.

5.3.3 Separate the extracted aggregates on a 4.75 mm sieve into coarse and fine aggregate fractions. Do ... Calculate the density of the coarse aggregate in the asphalt mixture by using a calculation based on the ... Coarse aggregate density and absorption values are
The bulk density is more in compacted state as compared to the loose which shows that the bulk density greatly depends on the degree of compaction or how densely it is packed. Usually increase in bulk density should be above 15 for coarse aggregate and should be below 15 for fine aggregate, But in our results it is 11.20 for fine aggregate and 11.48 for coarse aggregate.

For example, consider a concrete mix design that calls for 282-pounds of water i.e. free-water and contains 1100 pounds of fine aggregate and 2000 pounds of coarse aggregate. The mix design shows fine aggregate absorption to be 2 and coarse aggregate absorption to be 1. The batch plant operator measures the aggregate moisture and finds
