Non-Destructive Testing of Concrete (NDT)

April 26, 2017 TeamCivil Concrete, Tests

In this article “Non-Destructive Testing of Concrete” brief description is given for methods used to assess concrete strength and durability without damage. Non destructive test is a method of testing existing concrete structures to assess

Cement Setting and False Set

April 1, 2017 TeamCivil Concrete, Materials, Properties

Cement Setting Setting of Cement, or cement setting, is a term used to describe the stiffening of the cement paste. Setting refers to a change from a fluid to a rigid stage. Although, during setting, the

Splitting Tensile Strength of Concrete

March 27, 2017 TeamCivil Concrete, Tests

One of the important properties of concrete is “tensile strength” as structural loads make concrete vulnerable to tensile cracking. Tensile strength of concrete is much lower than its compressive strength (that’s why steel is used

In a previous post about cement and its components, we mentioned that there are four compounds of cement. They are: Silicates Alite, C3S Belite, C2S Aluminates Tricalcium aluminate, C3A Calcium alumino ferrite, C4AF Portland Cement Hydration

How Concrete is Made

March 10, 2017 TeamCivil Concrete, Materials

This post gives a basic outline on how the concrete is made. Simply, concrete is a mix of paste and aggregates. The paste, which consists of portland cement and water, coats the surface of the

Freezing and Thawing Damage to Concrete

March 9, 2017 TeamCivil Concrete, Durability

In this article, the damage caused by freezing and thawing cycles to concrete is described. Freezing-thawing damage results from the fact that when water freezes to ice, it expands by about 9 percent. When the water in

Compressive Strength Test of Concrete

March 6, 2017 TeamCivil Concrete, Tests

This test is considered as the most popular test performed on concrete in construction as it gives a general idea on the all the characteristics of concrete. Based on this test, one can either accept
