Cement Ingredients Percentage | Cement Chemical Composition What is Cement? Cement may be defined as the adhesive substance that unites the different fragments or masses together. The different types of concrete are mostly made through variations in cement. Who invented cement First? Joseph Aspdin first invented cement and named it Portland Cement. Portland cement is […]
History of Concrete | Concrete Origin | Oldest Concrete Structure Introduction to Concrete Civil engineering is the oldest type of engineering, which has influenced any civilization’s foundations ever lived. Civil Engineers have defined the standards of living. By applying its theories and methodologies, Civil engineering has revolutionized the world without any doubt. The Coliseum, […]
How to Break Up Concrete with Chemicals | Concrete Demolition Methods Concrete Demolition Methods Concrete is an exceedingly durable mixture. Their strength is designed to last for centuries. The need to demolish or remove concrete slab or structure often arises for many different reasons that may be due to a defect to it or undertaking a […]
Does Rain Affect Concrete Curing? | Concrete Curing Process. Concrete Curing Process For the hardening of concrete through the setting of constituent components and to promote the reactions in the concrete, curing is carried out. Curing is needed for three main reasons, i.e., for the dissipation of heat, reducing the moisture loss due to evaporation, and […]
Construction Joints | Control Joints | Expansion Joints Provision Construction Joints Construction movement joints are one of the most misunderstood and unappreciated technical issues in the masonry industry. Joints are used in brickwork to accommodate such movements and to avoid cracking. Masonry move because of temperature causes brick to expand and contract, moisture movement, and […]
Plastering in Construction and Pointing in Masonry Elements What is Plastering in Construction? Plastering is the application of a thin layer of mortar or concrete mix over the masonry wall surface. Plastering work covers the uneven surfaces and rough walls in the construction of houses with lime or cement mortar. A plaster acts as a […]
Cohesive Soil and Cohesionless Soil | Soil Liquefaction Cohesive Soil and Cohesionless Soil Generally, the soils are categorized in very different combinations, and the collapse of soil during excavation work depends on their properties. Mainly two types of soil which can be categorized are: Cohesive Soil Cohesionless Soil Cohesive Soil. Cohesive soils can be defined […]
What is Concrete?| Concrete Mix | Concrete Workability What is Concrete? A building material obtained by the mixture of cement, water, fine aggregate, and coarse aggregate is known as concrete. There are primarily four concrete types namely; Plain Cement Concrete Known as PCC. Reinforcement Cement Concrete Known As RCC. Pre-Cast Concrete. Pre-Stressed Concrete Plain Cement […]
Fine Aggregates | Specific Gravity of Sand / Fine Aggregate Fine Aggregates for Concrete Aggregates consist of sand, gravel, and stones, either crushed or and crushed or a suitable combination of them. Aggregate should be strong, hard, dense, durable, and free from injurious amounts of alkali. They should comply with the local Standard Code. Aggregates containing harmful material […]
Batching of Concrete | Weigh Batching | Volume Batching of Concrete What is Batching of Concrete? Batching is a process of measuring the ingredients in batches for mixing and is done either by weight or by volume. Volume batching is based on nominal mix and weight batching is based on design mix. The two common […]
