High-Strength Concrete - Portland Cement Association

High-strength concrete is specified where reduced weight is important or where architectural considerations call for small support elements. By carrying loads more efficiently than normal-strength concrete, high-strength concrete also reduces the total amount of material placed and lowers the overall cost of the structure.

Tensile Strength of Cement Determine the Tensile ...

Jun 04, 2012  Importance: Cement is usually subjected to compressive stresses when used in the form of concrete or mortar. The most comprehensive test for cement or for a mixture of it with sand is done by determining its crushing strength.Unfortunately, it requires a very costly machine and, therefore, the usual practice is to use the tensile test instead which can be carried out very cheaply.

Compressive strength - Wikipedia

Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to Tensile strength which withstands loads tending to elongate. In other words, compressive strength resists being pushed together, whereas tensile strength resists tension (being pulled apart). In the study of strength of materials, tensile strength ...

Compare the Strength Of Cement Mortar vs Lime Mortar

There are so many number of cement available, but there is only wrong application on it.Lime and Portland cement are equally useful. For workability condition, water is added more there is only density of concrete is higher not the strength. So concrete mortar is high strength when compared lime concrete. 4. REFERENCES [1].
