Cement & concrete blocks
Cement and concrete blocks are alternative materials for masonry construction. Concrete blocks have a glossier finish and higher strength than cement blocks but are more expensive with greater dead weight. Blocks come in solid, hollow, and cellular forms and various dimensions. Using blocks requires less mortar and construction time than other materials like bricks, resulting in lower costs. Proper storage, testing of strength and dimensions, and reinforcement of the blocks can improve durability. Aluminium is also used for partitions and has an aesthetic appearance while being light, durable, and reusable.

- 11. Determination of BlockDensity Three blocks shall be dried to constant mass in a suitable oven heated to approximately 1000C. After cooling the blocks to room temperature, the dimensions of each block shall be measured in centimetres to the nearest millimetre and the overall volume computed in cubic centimetres. The blocks shall then be weighted in kilograms to the nearest 10 gm. Density in kg/m3 = Mass of block in kg/Mass of block in cm2 * 106
