Mar 18, 2018· ix ratio of M25 grade is 1:1:2 (cement:sand:coarse aggregates) Assuming volume of concrete as 1 m^3 Therefore, Dry volume of concrete =1 x = m^3 cement = ( x 1)/(1+1+2) =/4 = m^3 since, Density of cement = 1440 kg/m^3 cement...
M25 mix has a ratio of 1 cement to 1 sand and 2 stone 1:1:2. This means cement volume is half of stone jelly prepare of concrete we need of jelly. So we need /2= of sand. So weight of cement required = =648 kg of 13 bags.
How can such a poorly expressed question be answered? How about working with the person who submitted the question to help him/her express it coherently. I was an editor once, and, particularly if English was not the person''s native language, I wo...
Allow the sand in the container to settle for 10 minutes, now measure the distance above the sand and upto the top of the container say Y. Now we can get the percentage of voids with this simple formula (100/X)*Y. Once we get the voids percentage we can calculate the cement and sand required for various cement mortars.
Concrete is basically a mixture of aggregates and paste. The aggregates are sand and gravel or crushed stone; the paste is water and Portland cement. Portland cement is not a brand name, but the generic term for the type of cement used in virtually all concrete. Cement comprises from 10 to 15 percent of the concrete mix, by volume.
Jun 11, 2010· At 30 minutes old, a yard of 4inch slump 123 concrete will typically contain about 6½ sacks of cement, 1850 pounds of stone, 1220 pounds of sand, and 300 pounds (36 gallons) of water. At 28 days, its w/c will deliver a compressive strength of 4500 psi.

To calculate a cubic yard of concrete, multiply the length, width, and depth of the concrete you need. The depth, as mentioned, is 4 inches, and the length and width are determined by measuring the area that needs to be filled.
Base preparation. For all types of bonded screeds (both sand/cement screeds and calcium sulphate screed) preparation of the base is of paramount importance. The structural concrete base should be at least C28/35 concrete with a minimum cement of 300kg/m 3. For precast units the surface of the units should be left rough during production and ...
Concrete is a material comprised of a number of coarse aggregates (particulate materials such as sand, gravel, crushed stone, and slag) bonded with cement. Cement is a substance that is used to bind materials, such as aggregate, by adhering to said materials, then hardening over time.
