Portland cement

Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout.It was developed from other types of hydraulic lime in England in the early 19th century by Joseph Aspdin, and is usually made from limestone.It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker

ESTIMATING CONCRETE MASONRY MATERIALS

For common batching proportions, 1 ton (2,000 lb, 907 kg) of masonry sand is required for every 8 bags of masonry cement. If more than 3 tons (2,721 kg) of sand is used, addton (454 kg) to account for waste. For smaller sand amounts, simply round up to account for waste. This equates to about 240 concrete masonry units per ton of sand.

Concrete Mix Ratio

2. Standard Mix Concrete Ratio. Nominal admixtures of fixed cement-aggregate ratios (by volume) vary widely in strength and may result in more or less rich admixtures. For this reason, minimum compressive strength is included in many specifications. These mixtures are called standard mixtures.. IS 456-2021 designates concrete mixes in several grades as M10, M15, M20, M25, M30, M35, and M40.
