ADVANCES IN CONCRETE SLABS: A REVIEW
Main Article Content
Abstract
Conventional slab is a simple method of construction in which top and bottom reinforcement has been provided & concrete has been poured. The pre-stress slabs are the method of construction in which the tendons have been provided with their curved profile and internal stresses have been developed. Bubble deck slab is a method of producing the gaps between concrete portions, so as to reduce the overall weight of slab. HDPEhollow spheres replace the concreteportionin the centerof the slab, which decreases theweightof slab and increasesthe efficiency of the floor. By introducing the gapsin the middle floor of slab , itreduces30 to 50% lighter slabas compared to solid conventional slab,which reduces the loads on the columns, walls and foundations and of course of the entire building. The aim of this paperis to discuss about the various properties of various types ofslab.The current study gives a brief idea about the different types ofslabs, their production and advantages. There are a number of green attributes of bubble deck slab and pre-stress slab over solid conventional slab including; reduction in total
