Recycled Aggregate Concrete (RAC) | Uses & Properties of Recycled Concrete | Steps involved

Requirement for coarse recycled concrete aggregate (RCA) as per BS8500

Recycled Aggregate Concrete Recycled Aggregate Concrete (RAC) is basically concrete mix that is prepared from crushed aggregates and concrete which has already been used in construction works. In the sector of construction engineering the key role of an engineer is to provide adequate quality products with the available materials. The products should be economical and … Read more

Admixture in Concrete & Admixture Types in Brief

Admixture in Concrete An Admixture is a compound which is usually a liquid that is added to a batch of concrete during mixing in order to adjust the properties of fresh or hardened concrete in a required manner. Most admixtures benefit concrete by decreasing the quantity of free water required for a given level of … Read more

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

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

Foundation-Protection-System-that-Keeps-Basements-DryFoundation-Protection-System-that-Keeps-Basements-Dry

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.
