The vermiculite lightweight concretes and prospects for their use in energy-efficient buildings

This article discusses the determination of the optimal consumption of vermiculite for residential buildings, as well as the concrete composition with high strength and other preferred properties at the same water and cement consumption. The main properties of local materials, namely vermiculite gravel, quartz sand and wollastonite mineral, were studied and their optimal composition for concrete was determined. Based on the experiments, it was found that lightweight concrete made from these raw materials has high strength and deformation properties, and recommendations were made for the use of such lightweight concrete in residential buildings.
