Calculate cement and sand requirements for construction projects. Supports various mix ratios, volume calculations, and material cost estimation.
Common ratios include: 1:3 for plastering, 1:4 for brickwork, 1:5 for general masonry, and 1:6 for foundation work. The ratio represents cement:sand by volume.
Multiply the total volume by the ratio components. For example, with 1:4 ratio and 1 cubic meter, you need 0.2 cubic meters of cement and 0.8 cubic meters of sand.
Factors include the type of work (plastering, masonry, foundation), exposure conditions, strength requirements, and local building codes and standards.
Multiply the volume ratio by the density of each material. Cement typically has a density of 1440 kg/m³, while sand density varies from 1500-1700 kg/m³ depending on moisture content.
