Lightweight Plastering Compound Using Volcanic Tuff

Abstract

Lightweight reinforced plaster coatings include a group of special types of textile concrete, which also includes concrete sheets, reinforced plaster coatings, including lightweight and heat-insulating ones. The basis for any type of textile concrete is a modified binder, the formulation of which is currently being developed by foreign and domestic research centers. active mineral additives (both natural and by-products of other industries) can be used in the binder, and it is also possible to use construction waste prepared accordingly. Development of the scientific basis for selecting the composition and the formation of a methodology for selecting the composition of the modified binder as the main component of textile concrete, including the use of finely ground construction waste obtained during the dismantling of construction projects, including within the framework of the housing renovation program. The purpose of the research outlined in the article was to develop a methodology for selecting the composition of the binder, predicting the properties and optimizing light plaster coatings based on a modified hydraulic binder, volcanic tuff and construction waste. The use of a composite binder will expand the possibilities of using these materials, and the introduction of finely ground waste will reduce the consumption of Portland cement clinker, which also increases the energy efficiency of such materials.
