Improvement of physical and chemical properties of concrete with brazilian silica rice husk (SRH)
The use of industrial and agricultural waste substitutions for Portland cement has greatly contributed to sustainable development practices. The increase in cement demand will be met by the use of supplementary cementing materials, in order to minimize the clinker consumption. In this study, the eff...
