An Experimental Analysis and Comparison of Properties of Concrete with Recycled Aggregates and Partial Replacement of Cement with Alccofine

Abstract

Increase in construction activities necessitates the utilization of raw materials in Concrete, particularly coarse aggregates which creates a threat to the untimely depletion of natural resources. Possible replacement materials would assist to slow down the risk of early exhaustion of natural resources. Recycled coarse aggregates (RCA) can supplement the natural coarse aggregates (NCA) which plays a crucial part in concrete. Past examinations demonstrates that the properties of RCA concrete are substandard in quality in contrasted with NCA concrete. This article endeavors to ponder the change in properties of RCA concrete with the expansion of mineral admixture named Alccofine. The exploratory examination was done to assess the change of the compressive quality of RCA concrete joining Alccofne. The Experimental investigation was carried out on six concrete mixes with a target characteristic strength of 30 MPa.Natural Coarse Aggregates were replaced by 25% and 50% of recycled Coarse Aggregates and Cement by 10% Alccofine. Compressive strength and Flexural Tensile Strength was found out. It was concluded that use of alccofine was advantageous in concrete made with recycled aggregates. Increase in compressive strength was observed by replacing cement with 10% Alccofine.
