Title: Mechanical Properties of Light Weight Concrete using Lightweight Expanded Clay Aggregate
Abstract: Abstract: This research investigates the impact of partially substituting coarse aggregate with light weight coarse material (LECA). In numerous aspects, LECA mirrors the properties of coarse aggregate. Because self-weight accounts for a major amount of the total load applied to the structure, LECA is utilized in concrete to lower the need for coarse aggregate and in the design of concrete buildings. This is crucial in circumstances like poor soils and tall constructions. It also offers significant advantages in terms of lowering concrete density, which improves labour efficiency. Lightweight concrete has a lower density than standard concrete and provides better thermal insulation. The main purpose of this study is to examine the weight and strength characteristics of concrete, such as cube compressive strength, split tensile strength cylinders, and flexural strength of light weight concrete versus conventional concrete by substituting LECA for natural aggregates by 25%, 50%, 75%, and 100%, respectively. For far over two millennia, lightweight aggregate has been used successfully. Keywords: Lightweight Expanded Clay Aggregate (LECA), Light-weight concrete, Flyash, Compressive Strength, Density.
