AB [EN] One of the growing demands in concrete manufacture is the availability of natural fineaggregates, which account for 35% to 45% of the total concrete. An alternative method of disposal offine recycled concrete aggregates (FRCA) generated from demolition and construction waste (C&DW)is their usage in mortar and the development of recycled mortar. The main aim of this researchwork is to evaluate the viability of incorporating FRCA from urban C&DW for the manufactureof cement-based mortars. Simple processing techniques like washing and sieving are adopted toimprove the FRCA quality. Physical and chemical characterization of ingredients is carried out.In total four mixes of 1:3 (cement: sand) mortar with partial replacement of normalized sand withFRCA (0%, 25%, 50%, and 100%) are evaluated for mechanical properties. Water to cement ratio forall four mortar mixes are determined by fixed consistency. Mechanical and physical properties likedensity, compressive strength, and flexural strength are studied for various curing periods, and theresult is that the optimum usage of FRCA is 25% based on a 90-day curing period.
