Performance assessment of water hyacinth-cement composite.
Water hyacinth (WH) is an invasive aquatic with an extensive, rapid growth. Nowadays, the considerable amount of WH biomass generated is a waste management challenge for those areas where WH is present. In this paper, a new insulation building material based on WH's petioles (WHP) and mixed with cement was analysed. Different WHPs particle sizes were processes (pulp WHPs and staple WHPs). As a consequence, two type of panel were studied. Both panels used different WHP content ranging from 40:60 (WHP:cement) to 100:0. According to the results, self-supporting WHP-cement board could be used as an alternative insulation material. The optimum percentage (WHP:cement) was 80:20 for panels made with pulp WHP and 75:35 for panels made with staple WHPs. Their thermal conductivity values were 0.63-0.45 W/mK respectively.
