| Summary: | Concrete is one of the oldest manufactured construction aterial used in construction of various structures around the world. Due to its high demand the material used for concrete production depleting every year. Thus, around the world new construction materials are being investigated. In this study local laterite aggregate was used as replacement of coarse aggregate. In this study, a total of three mixes were made of crushed granite aggregate as control mix, crushed granite aggregate replaced with 25% laterite aggregate and 25% laterite aggregate with the combination of 2.5% silica fume, and 30% slag replacing part of cement content, respectively. The scope of study includes the investigation on the compressive strength, flexural strength and splitting tensile strength. The main objective of the research is to study the mechanical properties of laterite aggregate concrete compared with crushed granite aggregate. However, before all of those tests were conducted the samples were tested using Ultrasonic Pulse Velocity (UPV) equipment to determine the pulse velocity. The method of study to be carried out is through the appropriate test of aggregates. The types of test done were sieve analysis, flakiness index and elongation index, and aggregate crushing value test. All the tests have been carried out and the results had been recorded and analyzed in appropriate table and graph. The experimental results show that the strength of normal laterite concrete is lower than the normal crushed granite concrete. |
