Cement - Wikipedia

Portland cement, the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-speciality grout, was developed in England in the mid 19th century, and usually originates from limestone. James Frost produced what he called "British cement" in a similar manner around the same time, but did not obtain a patent until 1822.

Clinker Production - an overview | ScienceDirect Topics

This conclusion was drawn from a series of tests in which Portland cement was ground either conventionally in a ball mill or in high-pressure grinding rolls. The water demand of the ball milled cement was 27 per cent and of the high-pressure ground cement was 32.5 per cent, at the same specific surface area (350 m 2 /kg).

Cement Types, Composition, Uses and Advantages of

There are several different types of cements of which Portland cement, Siliceous (ASTM C618 Class F) Fly Ash, Calcareous (ASTM C618 Class C) Fly Ash, slag cement, and silica fume are the major types [9, 10].They differ from their chemical composition. Table 2 gives the compositions of the above cement types in terms of SiO 2, Al 2 O 3, Fe 2 O 3, CaO, MgO, and SO 3, and the remaining can be

The clay in a finely crushed state is mixed with a definite amount of water in a pug mill. The mixture is then pressed into moulds, dried and finally burnt. To control the shrinkage, and accelerate the rate of production about 20 to 80% of burnt or calcined clay called Grog is mixed in the clay, while using flint clay, plastic clay is employed as binder.
