6 Special Cements for Concrete and Masonry Construction
Special cements are used to serve some specific functions in concrete and masonry construction. These functions can be altering the setting or hardening behavior of concrete, produce different architectural effects, enhance workability, impart water retention and plasticity of masonry, resist ...
What are the Products of Cement Hydration? [PDF]
The chemical reaction which takes place between cement and water is known as hydration of cement. This reaction is exothermic in nature, which means heat is released during the reaction, and the evolved heat is called as heat of hydration. ...
How to Develop High-Early-Strength Concrete? [PDF]
High-early-strength concrete can be developed using ordinary concrete constituents, special admixtures, and certain concreting practices. The high-early-strength concrete, which is also called fast track concrete, gains its specified strength at an early age compared to ordinary concrete. The time during ...
Applications of Rice Husk Ash in Building Constructions
Rice husk ash (RHA) plays two roles in concrete constructions. The first role is using rice husk as a substitute for Portland cement which leads to the reduction of the cost of concrete, and the other role is as an ...
Green Cement: Definition, Types, Advantages, and Applications
Green cement is an environmentally friendly product that minimizes carbon footprint of cement production. Many attempts have been made to produce green cements and several green cement types have been produced. The majority of these are based on technological advances ...
Test for Setting Times of Concrete Mixture Based on ASTM C403M-16
The penetration resistance test used for the determination of initial and final setting time of concrete mixture in laboratory and project site, and the effects of variables, such as water content; type and amount of cementitious material; or admixtures, upon ...
Grades of Ordinary Portland Cement Based on IS Codes
Ordinary Portland Cement(OPC) is the most widely used cement in the construction world. It is the basic ingredient for producing concrete, mortar, stucco, and non-specialty grouts. Ordinary Portland Cement is graded based on its strength. The grade indicates the compressive ...
