Bamboo reinforced concrete slab with styrofoam lamina filler as solution of lightweight concrete application

Abstract

Energy resilience is becoming more important nowadays especially in the field of building sustainability. Some implementations can be carried out including using recycled materials instead of nonrenewable materials such as steel. Hence, one of the investigation conducted in this paper is replacing steel reinforcement with bamboo bars and using recycled materials such as Styrofoam with the aim of producing a concrete element structure that is lighter and more economical. In this research stage, flexural strength test on bamboo reinforced concrete slab with Styrofoam lamination filler was conducted. The results showed that the flexural strength of specimens decreased by 15% but with the weight advantage of 20% less compared with those of normal reinforced concrete slab with the same dimension. It is considered good performance in practical design context, since the nominal flexural capacity of RC slab when designed with minimum reinforcement are usually much higher than the required moment.
