Concrete release agents are coating added on the surface of the formwork before pouring concrete. It helps to allow quick removal of formwork. The concrete releasing agent provides a smooth finished surface. Make sure that there should not be no debris in the mixed concrete. Concrete release agents comprise a mix of mineral oil, ester/plant … Read more
In this type of footing, at least two columns are supported in a row and a common foundation is provided. A combined footing is provided when the bearing capacity of the soil is low and required more surface area. Basically, It is made of reinforced cement concrete (R.C.C). Combined footing distributes the load from the superstructure to … Read more
What is Flyover? A flyover is an overpass, a high-level road bridge that crosses over a highway interchange or intersection. In this type of structure, one road carries over another. Flyovers are constructed to provide passage over an obstacle without blocking the path below. The passage needed maybe a road, highway, or railway. The development … Read more
The concrete block which has a core-zero area of more than 25% of the total surface area is known as a hollow block. Hollow blocks are lighter than conventional concrete blocks. These types of blocks are used for partition walls. Hollow blocks took less material which is why they are very light in weight. One … Read more
The bricks that have holes are known as hollow bricks. These bricks are also known as porotherm bricks. Hollow bricks are perforated either horizontally or vertically. Hollow brick is very light in weight and it reduced the dead load on the structure. Hollow bricks are very cheap because they took less material to manufacture. Hollow bricks provide a … Read more
What is Spandrel Beam? Spandrel beam is built along the circumferences of the slab. It is built along the external wall. Spandrel beam is also known as edge beam. Why Spandrel Beam is Provided in the Slab? A spandrel beam is provided in the slab when walls are not able to bear the weight of … Read more
A slab is a very important component of a structure. In ancient times, people used natural materials like mud, clay, bamboo to construct slabs. But the problem was that these slabs were not much durable or people did not have technical knowledge about materials. As civilization grew, peoples start innovating different materials to construct slabs. … Read more
Concrete is the mixture of water, cement, and aggregate in a suitable proportion. It possesses very high compressive strength. Concrete is combined with reinforcement to make it suitable for structural works. In this article, we will discuss the following properties of concrete. Workability of Concrete Segregation of concrete Bleeding in Concrete Compressive Strength of Concrete … Read more
Introduction: The rapid chloride permeability test of concrete is an in-situ test to check concrete permeability. This test is very simple and gives results very fast. Rapid Chloride Permeability test is powered by AASHTO T 277 or ASTM C 1202. The rapid chloride permeability test of concrete is conducted to check the Concrete’s Ability to Resist Chloride … Read more
The consistency test of cement is performed to calculate the amount of water content that is to be added to cement to attain Standard consistency or normal consistency of cement. In this standard or normal consistency test of cement, we will discuss the VICAT apparatus. So we will define it according to the Vicat apparatus. … Read more
