Rapid Hardening Cement – Manufacture, Properties and Uses
Rapid hardening cement is a special type of cement that achieves high strength in less time. Normally the strength achieved by conventional cements in 7 days is same as the strength achieved in 3 days. This type of cement is also ...
CHEMICAL AND PHYSICAL REQUIREMENT OF CEMENT
Cement is defined as the product manufactured by burning and crushing to powder an intimate and well-proportioned mixture of calcareous and argillaceous materials. The cement, which is generally used for preparing concrete, is the Ordinary Portland Cement. But for special ...
What is the Right Water-Cement Ratio for Mix Design?
A right water-cement ratio for concrete design will influence the compressive strength, permeability and the overall durability of the concrete structure. The idea of w/c ratio is that more the value, greater is the water content in the concrete and ...
Inhibitors Admixed Cement for Durable Concrete Construction
Inhibitors added cement is used for construction of durable concrete structures for longer life. The crack formation in concrete structure occurs due to the corrosion of rebar inside the concrete. This occurs because of the surface oxidization of iron rod ...
Properties of Various Grades of Ordinary Portland Cement
Properties of 33, 43 and 53 grades of Ordinary Portland Cement such as fineness, setting times, soundness, expansion, compressive strength based on Indian, American and Eurocodes. Ordinary Portland Cement(OPC) is the most widely used cement in the world for producing ...
Determination of Soundness of Cement by Le-Chatlier’s Principle
Soundness of cement can be defined as its ability to retain its volume after it gets hardened. This means that a properly sound cement will undergo minimum volume change after it converts into the hardened state. In the soundness test ...
Determination of Specific Gravity of Cement and Its Importance
The specific gravity is normally defined as the ratio between the weight of a given volume of material and weight of an equal volume of water. The portland cement have a specific gravity of value around 3.15. When it comes to ...
