Abstract

The objective of this research is developed the building envelope mixed with coconut fiber. The 6 ratios of Portland cement type 1 mixing of fine sand: coconut fiber: waterproofed liquid: tap water were designed which proportion to 1: 3: 0: 0.02: 0.5, 1: 3: 0.05: 0.02: 0.5, 1: 3: 0.1: 0.02: 0.5, 1: 3: 0.15: 0.02: 0.5, 1: 3: 0.2: 0.02: 0.5, and 1: 3: 0.25: 0.02: 0.5 by weight. The samples were tested to find engineering properties at 28 days of curing in ambient. According to the results, the suitable amount of coconut fiber can reduce the density and thermal conductivity, and increase the bending strength of building envelope mixed with coconut fiber. The 1: 3: 0.1: 0.02: 0.5 of ratio was the suitable ratio to use as the building envelope, and it had the properties as following: density 1,582 kg/m3, thermal conductivity coefficient 0.371 watt/m.Kelvin, water absorption 17.31 %, compressive strength 118 ksc, and bending strength 29 ksc. This developed building envelope can apply to cast and plaster as the walls in the building.
