Aggregates are used in concrete for several reasons. First, they reduce the amount of cement and water required to make the concrete mixture. This lowers the cost and environmental impact of concrete production. Second, they improve the strength and durability of concrete by resisting compression and preventing cracking. Third, they enhance the workability and appearance…
Aggregates also provide strength, durability, stability and resistance to various environmental factors. However, not all aggregates are suitable for every purpose. Some aggregates may have defects or impurities that can affect their performance and quality. Therefore, it is important to test aggregates before using them in construction projects. Testing aggregates can help to determine their…
Before getting straight to the topic, let’s have a small discussion regarding aggregates. Did you ever wonder, why aggregates are typically used in construction and engineering projects? Have you asked yourself why is it necessary to use aggregates and what is their importance? What happens if at all aggregates are not available in a particular…
RCC stands for reinforced cement concrete, which means that concrete is reinforced with steel bars to increase its strength and durability. Concrete is strong in compression while a minimum longitudinal reinforcement is provided in the column to assist tensile stress. Column is an important component of RC structure. It may be defined as a member…
In civil engineering, tests on aggregates are crucial to ensure the quality and suitability of materials used in construction projects. Aggregate is defined as a granular material, typically consisting of sand, gravel, or crushed stone, used in construction as a key ingredient in concrete and bituminous mixes. The properties and quality of the aggregate significantly…
Specific gravity is defined as the ratio of weight of the aggregate to the weight of an equal volume of water at a specified temperature. Procedure Where, A = Weight in gm of the saturated aggregate in water (A1- A2) B = Weight in gm of the saturated surface dry aggregate in air C =…
