Various types of concrete waterproofing are used such as Bitumen Membrane waterproofing, Cementitious Waterproofing, Liquid Membrane Coating, Bitumen Coating, etc. Concrete waterproofing is needed to provide an impervious layer and to avoid seepage in the concrete structure. Concrete waterproofing is the use of an impervious material layer on concrete that keeps water from penetrating the … Read more
In this article, I will describe why we test concrete strength after 28 days. As we know the strength of concrete is normally tested after 28 days. As time passes concrete gains strength but it is still unknown how much time concrete takes to gain 100 % strength. In the first 28 days, concrete gains … Read more
What Is Concrete Spalling? Concrete spalling is an incident in which concrete breaks itself and is free from structure. In concrete spalling, reinforcement bars are exposed to the atmosphere. The initial phase of the spalling problem does not look much serious but when bigger parts break and are free from structure then it creates a … Read more
What Is Foam Concrete? Foam Concrete is also known as Cellular Light Weight Concrete. Do not confuse with some other names like Lightweight concrete, Aircrete, Foamcrete, Low-density concrete. Foam concrete consists of fly ash, sand, and water. Sometimes Cement is used instead of fly ash. Further, Slurry is mixed with aerated foams in a concrete … Read more
Water-cement ratio is very crucial for the perspective of strength. Proper water-cement ratio is used to make concrete durable. In this article, I will discuss water cement ratio in detail. Let’s start! Have your senior boss on the construction site told you that “Add some water, the concrete looks extremely hard”? What do you think? … Read more
What Is Ready Mix Concrete? In Ready Mix Concrete, all concrete ingredients like cement, aggregates, and water are batched in the batching plant and then transported to the construction site with the help of a transit mixer in the truck. Concrete has a restricted lifespan between batching/mixing and curing. This means that ready-mixed concrete should … Read more
Definition The separation of Concrete ingredients from mixed concrete is known as Segregation. What Is Segregation Of Concrete? Separating concrete ingredients from each other refers to concrete segregation. Concrete segregation can reduce the strength of the concrete significantly. Concrete segregation may even cause leakage in a structure. Segregation occurs during the handling and placement of … Read more
Introduction Self Consolidating Concrete (SCC) is perceived as probably the best development in the concrete industry. Utilizing new admixtures and some mix changes, we can now create concrete that flows easily without segregating. Mixed concrete that segregates loses strength and creates honeycombed areas next to the formwork. Self-consolidating nature makes it very valuable because there … Read more
Concrete Mix Design is the procedure of selecting suitable proportions of cement, sand, and aggregates for concrete to achieve the desired strength in structures. In the Concrete Mix Design process each and every ingredient of concrete is tested in the laboratory. The Mix Design process is normally implemented for the structure that needs higher grades … Read more
What Is Honeycomb In Concrete? Honeycomb define as rough, pitted surfaces or voids in concrete resulting from the incomplete filling of the concrete against the Formwork. The surface looks very rough with a void and gap between concrete and reinforcement. It resembles the Honeycomb. Honeycomb is a very serious problem that not only decreases the … Read more
