Resumo


Current research evaluated the use of Pinus sp. wood dust from lumber industries wastes on the composition of wood-cement panels. The experiment comprised the manufacture and characterization of wood-cement panels with granulometry-controled wood dust, without any previous treatment, and four chemical accelerating admixtures (calcium chloride, magnesium chloride, aluminum sulfate and sodium silicate). Results showed that chloride admixtures had excellent behavior and the highest performance. The combination of wood dust and calcium chloride admixture had the best performance for the properties under analysis within the chloride admixtures.
