Utilization of cassava trunk waste mixed with cement to particle board wall for thermal resistance in building

Abstract

This research aims to study the properties of cement bonded particle boards mixed with cassava trunk wastes. The Portland cement type1: fine sand: tap water ratio was equal to 1: 0.5: 0.416 by weight. The ratios of cassava trunk waste to cement were added following: 0.05, 0.06, 0.07, 0.08, 0.09, and 0.10 by weight. The cassava trunk wastes were crushed by the wood grinder with sieve no.4. The casting of particle board walls used the compression machine in room temperature (30 – 35 degree of Celsius) and control 0.75 g/cm³ of density. The TIS 878-2537 standard (cement bonded particle board: high density) was cited to the property tests of cement bonded particle boards. Resulting, the ratio 0.08 of cement board mixed with cassava trunk can use as the particle board walls which have good thermal insulation property.
