To Study the Effect of Addition of Lightweight Expanded Clay Aggregate on fresh and hardened properties of Concrete
Keywords:Lightweight Expanded Clay Aggregate Concrete, Lightweight Concrete, Compressive Strength, Spilt Tensile Strength, Flexural Strength
An attempt is made in this study to evaluate the behavior of partially replaced coarse aggregate with light weight expanded clay aggregate (LECA) on various properties of the concrete. The performance of the concrete using LECA is not known much. The main goal of this study is to examine the compressive strength, split tensile strength and flexural strength of the concrete using LECA with replacing normal aggregate by 0- 100% in the increment of 25%. The result indicated that maximum reduction of weight is about 28% and strength reduced by 17% for 100% Replacement. The optimum dosage of replacement without affecting strength is 25%. This study shows that the performance of the developed LECA mixed concrete helps to reduce the weight of structure if a suitable mix design are provided.
