This study aims at characterizing cement panels reinforced with mosso bamboo biomass (Phyllostachys pubescens) and biomass of sugarcane bagasse (Saccharum officinarum) with addition of blast furnace charcoal slag to the mix. The physical and chemical characterization of the materials were carried out. Afterwards, an inhibition test was performed to analyze the compatibility of the powders with Portland cement. The treatments adopted were: immersion in cold water, immersion in hot water, sodium hydroxide, sodium silicate, silane and calcium chloride. The composites compressive strength was analyzed with the addition of different mixes of blast furnace charcoal slag. Finally, the physical and mechanical properties of the panels made of vegetal biomass, Portland cement and blast furnace slag were determined. The results of the inhibition test, made with plant biomass shows that the addition of calcium chloride to the blend is the most efficient treatment to reduce the inhibition rate of the biomass of mosso bamboo and biomass of sugarcane. For composites with blast furnace slag, the inhibition test showed that the addition of 50% blast furnace slag proved effective in increasing compatibility, thus improving compressive strength. In this case, the treatment with 40% slag content presented superior resistance to the other traces. For the cement-vegetal biomass panels the study found out that the mosso bamboo biomass presents total feasibility for the preparation of panels whereas the sugar cane biomass is not feasible. The relevance of this study is the use of industrial waste, such as vegetal biomass and slag, for the production of new construction materials. |
