Thereby, lots of cement consumption for brickwork is required. Depending on the quality of bricks, the brickwork is classified into three categories. First Class Brickwork, it is perfect for load bearing walls as the minimum crushing strength of the bricks used is 105 Kg per sq The cement sand ratio for brick masonry is 13 to 16.

These blocks were made of cement 1.25 parts, lime 0.5 part, sand and gravel 6 parts, and were tamped from damp mixture. it is probably safe to assume that the minimum crushing strength of well-made blocks, 1 to 5, is 1,000 pounds per square inch at 1 month and 2,000 pounds at 1 year.
Density of concrete masonry block. as said above, 3 blocks shall be taken to conduct this test. to determine the density of block, first heat the block in the oven to 100 o c and then cooled it to room temperature. now take the dimensions of block and from that find out the volume and weigh the block.
Cement. these blocks are normally made out of local sand, cement and water. the cement performance seems to be particularly low in this type of applications. the performance indicator studied was the block compressive strength in mpa nmm2,
Take 200gm of cement and 600gm of standard sand in the proportion 13 by weight in a pan. the standard sand shall be of quartz, of light, gray or whitish variety and shall be free from silt. the sand grains shall be angular, the shape of grains approximating to the spherical form, elongated and flattened grains being present only in very small quantities.
