Grillage Foundation Grillage foundation is used to bear heavy structural loads from the columns, and beams. Heavy loads are needed to transfer over large areas. Grillage foundation avoids deep soil excavation because of load transfer over the large area. The typical depth of the grillage foundation is restricted from 1 meter to 1.5 meters. Grillage … Read more
RCC beam can be classified as balanced, under-reinforced, and over-reinforced sections based on the percentage of reinforcement it has. In this post, I have discussed the balanced, under-reinforced, and over-reinforced beam sections. Balanced Beam Section Reinforced concrete beam (RCC) sections in which the tension steel also reaches yield strain at the same time as the … Read more
In a doubly reinforced beam, reinforcement is provided in the tension zone and compression zone. (as shown in the above figure). The moment of resistance can not be increased by increasing the amount of steel in the tension zone. It can be increased by making the beam over-reinforced but not more than 25 percent on … Read more
Ferrocement is a thin reinforced concrete in which the cement mortar is reinforced with small diameters of steel wire meshes spaced closely. Mortar provides the mass and the steel wire mesh gives tensile strength and ductility to the structure. This system shows high tensile strength to weight ratio and good cracking performance. It is also … Read more
Underpinning is a procedure used to repair, strengthen, or increase the depth of an existing foundation by lowering the footing to permit it to rest on more supportive soil. In this technique, a new foundation is built under the old foundation, or the old foundation is repaired. Methods of Underpinning Pit Method Cantilever needle beam method Pier and beam … Read more
In this article, we have covered the difference between Singly Reinforced Beam and Doubly Reinforced Beam based on reinforcement in tension and compression zones of the RCC beam. Singly reinforced beam and double reinforced beam are two common types of reinforced concrete beams widely used in construction. These beams resist bending and shear forces to … Read more
This blog post is related advantages of thermal insulation in buildings. Let us get started. Thermal insulation is used to separate the building temperature from the external environment. Due to thermal insulation building interior is less affected by external temperature. Warm protection helps safeguard a structure’s inside so that it’s less impacted by the outside … Read more
High alumina cement or HAC is a unique concrete, fabricated by blending bauxite (aluminum ore) and lime at a specific temperature. This Cement is also known as Calcium Aluminum Cement (CAC). It is determined that the complete alumina substance should not be less than 32% and the proportion by weight of alumina to the lime … Read more
Waterproof Cement: Introduction Waterproof cement is manufactured by mixing a small percentage of metal stearates (Al, Ca) with ordinary cement, during the grinding period. Waterproof cement, also known as waterproof concrete or hydrophobic cement, is a specialized building material designed to resist the penetration of water. So it has only one difference that it contains … Read more
A machine foundation is used to transmit the dynamic and static load to the soil due to the weight of the rotating vibrating machine. The dynamic load is little compared to the static weight of the machine. It basically comprises a mass of concrete. In a Machine Foundation, the dynamic load is applied monotonously over … Read more
