Product development of light weight concrete wall board mixed with coconut leaf waste for small community enterprise

Abstract

The objectives of this research are to study the product development of light weight concrete wall board mixed with coconut leaf waste for small community enterprise to find the suitable coconut leaf waste mixed ratio with cement, river sand, coconut leaf waste, water and catalyst accelerator at 1:0.4:0.13:0.33:0.03 ratio. CC13 (1:0.13) at 28 days has density 2,266 kg/m3, bending resistance 3.05 MPa, heat conduction efficiency 0.236 W/m-K. The coconut leaf waste can absorb water inside and the cement board can attach to the concrete wall easily. Suitability to make the big concrete wall.
