An Experimental Investigation of Lightweight Self Compacting Concrete with Replacement of Coarse Aggregate as Pumice Stone- A Review

Abstract. Due to its unique properties as compared ordinary concrete, lightweight concrete play a major role in construction sector. Here, this research explain the development of self-compact by replacing coarse aggregate together pumice stone, which is used material various proportions. An investigation on effect partially replaced with stone carried out. The fresh and hard property self-compacting have been studied results normal concrete. Pumice due special such unit weight, heat insulation property, resistance against fire when we combined coating substance has improved. Several concretes flow diameter, diameter after an hour, V-funnel L-box tests, 28 days split- tensile strength, dry test, water absorption 7- 28-day compressive ultrasonic pulse velocity test was investigated. According study, include segregation resistance, filling capability natural aggregate, at levels 20%, 40%, 60%, 80% volume fly ash blast furnace slag minerals constant rate 40%. weights, thermal conductivity addition ultra-sonic were obtained. compression, flexural, split strengths cubes, cylinders, along prisms are tested for 7, 14, days. Results shows that met requirements structural applications.
