Therefore, the chemical, physical and mechanical characteristics of the aggregates used in the mixing greatly affect the properties of the resulting concrete (such as compressive strength, strength, durability, weight, production costs and others). The aggregate weight used will determine the weight of the concrete produced. In general, a good aggregate must be an aggregate that has a cuboid or round shape, clean, hard, strong, well graded and chemically stable. The aggregate is divided into two groups, namely as follows.
The characteristics of the shape and outer texture of the exposed aggregate play an important role in the properties of concrete. Particles with a high surface area to volume ratio can reduce the workability of the concrete mixture. Flaky aggregates can be detrimental to the durability of the concrete because it tends to be … Read More
