How Concrete is Made

In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.

Portland Blast-furnace Slag Cement / ASO CEMENT

Portland Blast-furnace Slag Cement. A Portland cement mixed with a designated amount of ground granulated blast-furnace slag. The latent hydraulic property of the blast-furnace slag gives excellent long-term strength. Properties Significant chemoresistance, and Suppression of alkali-aggregate reaction (type B and C). Applications

Rapid Hardening Cement| Concrete Construction Magazine

Portland cement concrete is prone to drying shrinkage cracking. It is susceptible to attack by sulphates and has an undesirable reaction with certain aggregates (ASR). Generally, when one accelerates the gain in strength of portland cement concrete through finer grinding or chemical additives, there is a significant increase in drying shrinkage.

53 Grade Cement, OPC 53 Grade Cement– Jklakshmi

For 53 Grade OPC Cement, the minimum compressive strength achieved by the cement at the end of the 28th day shouldn't be less than 53MPa or 530 kg/sqcm. Interesting Fact. OPC 53 Grade and OPC 43 Grade Cement are similar in chemical composition but different in the grinding process. During the final stages of the grinding work, the higher .

Bogue calculation - Understanding Cement

The standard Bogue calculation refers to cement clinker, rather than cement, but it can be adjusted for use with cement. Although the result is only approximate, the calculation is an extremely useful and widely-used calculation in the cement industry. The calculation assumes that the four main clinker minerals are pure minerals with compositions:

Concrete: Scientific Principles

Table 2: Composition of portland cement with chemical composition and weight percent. When water is added to cement, each of the compounds undergoes hydration and contributes to the final concrete product. Only the calcium silicates contribute to strength. Tricalcium silicate is responsible for most of the early strength (first 7 days).

Chemical Demolition of Concrete (Expansive, Non-Explosive)

When you think concrete demolition, sights and sounds of big, whirring saws and blades come to mind. While it is often the case that heavy equipment has to be brought out to accomplish demolition, there is an increasing demand for the use of chemical demolition agents on construction sites.

Properties of Cement

Mar 02, 2017 · Setting Time • Cement paste setting time is affected by a number of items including: cement fineness, water-cement ratio, chemical content (especially gypsum content) and admixtures. • For construction purposes, the initial set must not be too soon and the final set must not be too late. Normally, two setting times are defined: • Initial set.

Other additives sometimes used are ethylene glycol, oleic acid, and dodecyl-benzene sulphonate. The most notable type of cement produced is Portland cement, but certain active ingredients of chemical admixtures may be added to clinker to produce other types of cement, such as: ground granulated blast furnace slag cement; pozzolana cement

Chemical Composition of Cements

In considering the value of a cement or fireclay, it must be remembered that the mere chemical composition is by no means the sole guiding point. In the case of a cement the degree of fineness, tensile strength, and other points also require determination ; therefore the necessary tests may be subdivided into two classes — chemical and .
