To calculate how much gravel you need to cover a rectangular area you need to multiply the volume by the gravel density. The volume formula for a rectangular (or square) box in cubic feet is height (ft) x width (ft) x length (ft), as seen in the figure below: For example, to fill a box with a width of 3ft and a length of 6ft, to a depth of 1ft ...
Coarse‐grained soils have particles with a diameter larger than 0.075 mm (the mesh size of a #200 sieve). Fine‐grained soils have particles smaller than 0.075 mm. The four basic grain sizes are indicated in Figure 1 below: Gravel, Sand, Silt and Clay.
40 mm size aggregate wieght per cum depends upon the type of rock of which the aggregate is made of. But in general, the 40 mm size aggregate may have 1.6 MT to 1.8 MT of wieght in 1 CUM volume. 1.8 is for the high density rocks such as granite e...

In the step 3 of "How To Calculate Quantities Of Cement, Sand And Aggregate For Nominal Concrete Mix (1:2:4)" you have calculated that: 01 cum of concrete will require Cement required = 1/0.167 = 5.98 Bags ~ 6 Bags Sand required = 115/0.167 = 688 Kgs or 14.98 cft Aggregate required = 209/0.167 = 1251 kgs or 29.96 cft
Aggregates comprise as much as 60% to 80% of a typical concrete mix, so they must be properly selected to be durable, blended for optimum efficiency, and properly controlled to produce consistent concrete strength, workability, finishability, and durability (Photo 1). The ingredients in conventional concrete mixes usually fall within these ...
Both coarse aggregates (particle sizes of 20 mm to 4 mm) and fine aggregates (particle sizes less than 4 mm) are required but the proportions of different sizes of coarse aggregate will vary depending on the particular mix required for each individual end use.
Feb 07, 2019· The size of the aggregate used for PCC varies from 10-12 mm to 40 mm depending on where they are to be used. If the size of the aggregate is more, it results in the reduction of cement consumption. Coarse aggregate shall be clean and free from elongated, flaky or laminated pieces.

University of Central Florida. The molarity of 30% H2O2 solution is 9.8 M. To make 40 mM solution, you should dilute 30% solution 245 times, i.e. mixing of 1 mL of 30% H2O2 with 244 ml of H2O will ...
Thus, the quantity of cement required for 1 cubic meter of concrete = 0.98/0.1345 = 7.29 bags of cement. The quantities of materials for 1 m3 of concrete production can be calculated as follows: The weight of cement required = 7.29 x 50 = 364.5 kg. Weight of fine aggregate (sand) = 1.5 x 364.5 = 546.75 kg.
You would usually lay a 10mm aggregate at a depth of 30-40mm, but on a driveway this would need to be at least 50mm. A 20mm aggregate would need to be at least 40-50mm deep, and at least 50-60mm on driveways. A larger aggregate will settle and bond together better than smaller ones. The depth you will need to select for your gravel or slate ...
The two types of aggregates are given below. Fine aggregates. Coarse aggregates. 1) Fine aggregates:- The aggregates whose size is less than 4.75 mm are known as fine aggregates. Fine aggregate is also known as sand. 2) Coarse aggregate:- The aggregate whose size is greater than 4.75 mm is known as coarse aggregate.
