Flexural Behaviour of the Two-Way Spanning Reinforced Concrete Slab Using Spherical Plastic Bubble Balls

Abstract The use of conventional reinforced concrete in the construction industry increases each year, especially developing countries. However, content, particularly cement production contributed to greenhouse gas emission subsequently increase climate change. Thus, slab containing high-density polyethene (HDPE) hollow spherical plastic bubble balls also known as deck slabs were introduced for sustainable construction. This type forms a that has less volume compared normal solid slab. Although this unique system can facilitate up 50% longer span slab, yet, it cause performance structure such flexural and shear capacity may be affected due thirty forty per cent fewer volumes. Hence, paper studies comparison two-way supported slabs; after being subjected area loading. square are 1200mm by width length with thickness 235mm. investigations experiments included strength, bending stiffness load-deflection behaviour impact Also, crack propagation pattern which differs was shown system, strength.
