ACTIVITY OF HIGHLY PERFECT FILLERS FOR THERMAL INSULATING DRY BUILDING MIXTURES
The effectiveness of the use of four materials as a high-porosity filler in a heat-insulating calcareous dry mortar mix: glass hollow microspheres, ash microspheres of aluminosilicate, expanded vermiculite sand, expanded perlite sand. The pozzolanic activity of the test excipients was determined. It was revealed that on the surface of the glass hollow microspheres, the formation of the reaction with lime formed neoplasms -calcium hydrosilicates. The high efficiency of using hollow glass microspheres as a filler in heat-insulating plaster solutions has been confirmed.
