Portland cement - Wikipedia
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
Cement Replacement Material - an overview | ScienceDirect,
Reduce cost of raw materials (assuming CSF is used to save cement). • Increase cost of production and possibility of errors in mix proportions. • May improve durability. • Require better curing, and therefore increase cost of placing. GGBS can cause bleeding, but PFA generally improves cohesion. • PFA and CSF produce a darker colour mix.
Calculate Cement Sand & Aggregate - M20, M15, M10, M5,
Hence, to prepare 1 cubic meter of M20, M15 and M10 concrete, 1.57 cubic meters of “total dry volume” of cement, sand and aggregate are needed, whereas to prepare 1 cubic meter of M7.5 and M5 concrete, 1.52 cubic meters of “total dry volume” of cement, sand and aggregate are needed. Many websites are giving different values for the “total dry volume” of the ingredients.

Concrete: Cement Substitutes - GGBS, PFA and more
Concrete made with GGBS cement sets more slowly than concrete made with ordinary Portland cement, depending on the amount of GGBS in the cement mix, but also continues to gain strength over a longer period leading to improved overall durability and life expectancy. Silica fume. Silica fume is a by-product from the manufacture of silicon.
Soundness Of Cement | Soundness Test Of Cement | Le,
The soundness test of cement determines the expansion of cement after it starts setting. Certain cement has been found to undergo a large expansion after setting causing disruption of the set and hardened mass. This expansion of cement can cause serious problems for the durability of structures when such cement is used.
