FINENESS OF CEMENT iricen.gov

FINENESS OF CEMENT 1. Objective The fineness of cement has an important bearing on the rate of hydration and hence on the rate of gain of strength and also on the rate of evolution of heat. Finer cement offers a greater surface area for hydration and hence faster the development of strength. The fineness of grinding has increased over the years. But now it has got nearly stabilized.

Manufacturing of Portland Cement Process and Materials

The manufacture of Portland cement is a complex process and done in the following steps grinding the raw materials, mixing them in certain proportions depending upon their purity and composition, and burning them to sintering in a kiln at a temperature of about 1350 to 1500 ⁰C. During this process, these materials partially fuse to form nodular shaped clinker by broking of chemical bonds of

Rawmill Wikipedia

A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill.The raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a large effect upon the

Ground granulated blast-furnace slag Wikipedia

Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.Ground-granulated blast furnace slag is highly cementitious and high in CSH (calcium silicate hydrates) which is a strength enhancing

Fineness of cement curiouscivileng

High fineness cement will rapidly hydrate, which can generate a high heat of hydration. The high heat of hydration can adversely affect the fresh concrete by causing tensile stress more than the strength of fresh concrete, which can create cracks. Also, the fineness of cement should not be low because this will result in a low rate of hydration and a low rate of gaining strength. Therefore it
