gravel‚ or crushed stone that‚ along with water and Portland cement. Aggregates are essential ingredient in concrete. For a good concrete mix‚ aggregates need to be clean‚ hard‚ strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete. Aggregates‚ which account for 60 to 75 percent of the total volume of concrete‚ are divided into two distinct categories - fine and coarse. Fine aggregates generally consist of natural sand

What are the differences between Concrete structure and Steel structure? And for what purposes is it better to use concrete or steel structures? Concrete is the second most used material for construction after water in the world. Concrete is widely used in today construction industry because of its durability and compatibility. It can be mounded in any shape which makes it a very useful. In addition to the unique aesthetics achieved with concrete construction. Steel has the highest strength-to-weight

aggregate particles improve the workability of fresh concrete during mixing so they are good for preparing portland cement concrete. * Angular and rough particles are good for asphalt concrete and base courses because they increase increase the stability of the materials in the field and reduce rutting. * Flaky and elongated aggregates are difficult to compact during construction and are easy to break so they are should not be used for asphal concrete. * Soundness and Durability: * Soundness
