Strength Properties of Self Curing Concrete using Light Weight Aggregates

Abstract

The effectiveness of conventional compaction methods may be hampered in projects that have a high density of reinforcement, resulting in increased labor and construction time requirements. The inclusion of self-compacting qualities is crucial for improving the surface smoothness, strength, and durability of concrete. In addition to compaction, the process of curing has similar significance in achieving the desired strength and durability of concrete. Traditional curing methods are often associated with a substantial need on human effort, extended time periods, and notable expenses. Furthermore, the development of self-curing concrete may be attributed to other causes, including the inadequate curing process and limited water availability in arid locations. The workability properties of self-compacting concrete (SCC) mixtures, which incorporate up to 15% prewetted lightweight expanded clay aggregate (LECA) and fine aggregate admixture (FAA), satisfy the workability requirements outlined by the European Federation for Specialist Construction Chemicals and Concrete Systems (EFNARC). The objective of this research was to examine the influence of prewetted lightweight aggregates as self-curing agents on the mechanical properties of the self-cured hardened selfcompacting concrete (SCC). The primary objective of the study was to evaluate the impact of several factors on many mechanical properties, including compressive strength, split tensile strength, modulus of rupture, modulus of elasticity, pullout behavior, and flexural behavior. The experimental findings have consistently shown that the SCSCC mixes exhibit improved mechanical properties in comparison to the control mix.
