· Cement manufacturers mine and process raw materials and put them through a chemical reaction process to create cement. They need to understand the chemical composition of the raw materials so that the reaction in their process takes place correctly and they make good, high quality cement that will eventually be used to make concrete by contractors and "ready-mix" companies.

The results of shaft lining monitoring gave rise to an investigation of cracks observed in the structure. An hypothesis was made that the cracks might be due to stresses caused by energy wave propagation, triggered during blasting or by the rock falls. However, it could not be excluded that the cracks had their origin in the rheologic changes taking place in the concrete. To prove the ...
Sprayed concrete as a construction process for conventional tunneling presents different advantages, such as: It provides an immediate support. It permits adoption of non-circular shapes. It allows rapid installation of structural support through the shell lining, without the use of any formwork.

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.
