Role of Water in Concrete Water is the most important & least expensive ingredient of concrete. It plays an important role in mixing, laying, compaction, setting & hardening of concrete. The strength of concrete depends on the quality & quantity of water used in the mix. The functions of water in the concrete mix are … Continue reading Role and Quality of Mixing Water in Concrete
The following 15 precautions should be taken during the preparation of good-quality concrete: 1. The cement and aggregates should be adequate in quality and it should ensure that they meet the required specifications to achieve the desired strength and durability of concrete. 2. The aggregate should be hard and durable. And, it shall be properly … Continue reading 15 Precaution To be taken To Prepare a Good Quality of Concrete
Definition Of Curing Of Concrete The process of keeping the concrete surface moist for a certain period after its finishing is called curing. Necessity of curing Curing prompts continuous hydration of cement and thereby helps in acquiring full strength. Curing also helps in improving: The durability, Impermeability, Weather-resisting qualities, And reduces shrinkage. If curing is … Continue reading Define Curing Of Concrete || Necessity of Curing
The concrete is cured by any of the following methods, depending upon the type of construction work, Following are the 9 methods for curing of concrete. 1. Covering In this method of concrete curing, the newly laid concrete surface is covered by wet gunny bags or hessian, which are wetted periodically. This curing method is … Continue reading 9 Methods for Curing of Concrete – Know Before Concreting
What is Concrete? When a binding material (cement or lime), fine aggregate (sand or surkhi), coarse aggregate such as crushed stone, broken bricks, etc. and water are mixed in suitable proportion, they form an easily workable mix, known as plastic or green concrete. When this plastic concrete becomes hard like a stone, this is termed … Continue reading 15 Types Of Concrete Classification- According to specification | level of control | binding materials | design | purpose
Grade Of Concrete Concrete is generally graded according to its compressive strength as per IS-156,2000, there are fifteen grades (M10 to M80) of concrete in the designation of concrete mix, the letter M refers to the concrete mix and the number refers to the specified characteristic strength of concrete at 28 days expressed in MPa. … Continue reading Grade Of Concrete
Fiber Reinforced Concrete Fiber reinforced concrete is a composite material consist of conventional concrete reinforced with fine fibers. The commonly used fibers are steel fibers, glass fibers, organic polymers fiber etc. Plain concrete is weak in tension and has a low resistance to cracking. This weakness can be removed by the inclusion of fibers in … Continue reading Fiber Reinforced Concrete
