Flexural Strength of Concrete

One-point loading test and the Two-point loading test For Flexural Strength of Concrete

Flexural strength of Concrete, also known as Modulus of rupture, is an indirect measure of the tensile strength of unreinforced concrete. Modulus of rupture can also be defined as the measure of the extreme fibre stresses when a member is subjected to bending. Apart from external loading, tensile stresses can also be caused by warping, … Read more

Self-healing Concrete | How Self Healing Concrete Works

Self-healing Concrete

What is Self-healing Concrete? Self-healing Concrete is defined as a type of concrete that exhibits self-healing properties. Self-healing or self-repairing of concrete is that property by which concrete undergoes crack repair and rectification, either by autonomous or by autogenous methods. The characteristics of concrete that defines all of these activities is it’s durability. Durability is … Read more

clouds cold freezing frost

Cold Weather Concreting As per ACI 306-R10, Cold Weather Concreting is defined as a concreting process – mixing, pouring and curing, below atmospheric temperature of 4o Celsius (40 o F) over the recommended protection period as per the specifications. Protection period is defined as the time required for the concrete to develop early strength of … Read more

All about Concrete Admixtures | Dosage & Cost | Admixture Market in India


Concrete Admixtures Concrete Admixtures are those ingredients or additives (other than aggregates, cement, water) added to the concrete during the time of mixing to enhance or alter its mechanical and material properties. The desired characteristics such as high workability, high compressive strength, setting time, and durability parameters can be altered by the addition of admixtures. … Read more

Effects of Capillary Water on Structures and Foundation | Preventing damage


What is meant by Capillary water in buildings? Construction materials, like concrete, aggregates and sand, are porous and allows water molecules to rise due to capillary action. This creates a ring of dampness in base of buildings or structure including lateral walls due to accumulation of capillary water. The principle behind the capillary rise is … Read more

Cracks in Concrete | Types & Causes of Concrete Cracking

Flexural cracks on pavement slab due to lack of reinforcement or expansion of subgrage - EngineeringCivil.org

Cracks in concrete are quite common phenomena. But unforeseen cracking in concrete that are not anticipated in design stage, affects the durability and integrity of structure. This in-turn results in poor performance on the structure over its service life.

Reinforced Cement Concrete (RCC) | Simple Explanation | Significance

Reinforced Cement Concrete (RCC) Definition of Reinforced Cement Concrete    Reinforced Cement Concrete (RCC) is a composite building material consisting of structural concrete reinforced with a reinforcing material like steel. The most common reinforcement used is steel, due to its complimentary properties and it is called steel reinforced cement concrete or simply Reinforced Cement Concrete. … Read more
