  • Abstract:
  • This experimental deals with floating concrete precast slab with addition of vermiculite and pumice. Buoyancy plays major role on floating objects. In order to design a floating concrete slab Light Weight Concrete (LWC) plays a prominent role in reducing the density and to increase the thermal insulation. Light weight concrete (LWC) is formed by Natural aggregate, synthetic light weight aggregate. Vermiculite is a light weight and cheap product because of its thermal resistance has become a valuable insulating material. The density of these concrete varies from 750 Kg/m³ to 2050 Kg/m³. Pumice is a natural graded light weight coarse aggregate which has a dry density of 1200 Kg/m³ to 1450 Kg/m.The light Weight Concrete (LWC) M20 using the light weight coarse aggregate as Pumice stone as a full replacement to 100%, light weight fine aggregate as Vermiculite as a replacement of fine aggregate to 75 %. The Cement (Ordinary Portland cement) is partially replaced by Fly Ash up to 50 % and some other mineral admixture are added which are Steel Fibre and Super plasticizer (SP 430) are added. An experimental work concludes in which the compression strength of conventional mix has higher strength and weight. Due to floating condition the specimen must have less density so, specific proportion has low density while comparing to other mix. Even though the mix 4 has low strength but it has low density and it is used in precast floating slab. The slab isdesigned to float above the datum line and with a load carrying capacity of 1.5 kN. The mix also yields on compressive and split tensile strength of 5.07 N/mm2 and 2.17 N/mm2.
