Comparative Study on Light Weight Concrete by using Light Expanded Clay Aggregate and Pumice Stone

In order to increase compressive strength while decreasing thickness and weight, lightweight concrete is crucial to the construction of concrete. By including clay and pumice into the composite, the study focuses on analyzing the qualities of the composite sample (M20) both when it is fresh and when it has hardened. Our unique mixes, which each have three cubes and three cylinders, are made to measure compressive and bending strength in addition to mix control. This study also looks into adding different mineral admixtures to the concrete mixture. The test results showed that across several trials, strength and weight loss improved concurrently. Thus, it can be said that lightweight aggregates have greater qualities than pumice stone and regular concrete, particularly lightweight expanded clay aggregate stone.
