Contractors that handle municipal projects requiring the mass pouring of concrete have their work cut out for them. From construction delays to compliance issues, there are a lot of things that can go wrong, and that’s a big problem for dam construction. These structures must be perfectly engineered and can’t afford to sustain any kind … Read more
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 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, 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
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
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
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
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 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) 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
