Autoclave Synthesis of Composite Cements on Magnesium Silicates
Abstract The use of various mineral additives in the production of cements and concretes is one of the urgent tasks of building materials science, as it reduces the consumption of Portland cement clinker, the production of which is accompanied by a large consumption of electricity and the release of...
