Possibilities of Using Waste Diatomaceous Earth for Polymer-Modified Mortar

Article Preview

Abstract:

The paper focuses on results obtained in solving the research and development project of lightweight Polymer-Modified Mortars (PMM). With regard to the currently on-going repairs and reconstructions of panel houses in the Czech Republic approaching the end of their expected lifetime, attention is paid to PMM (Polymer-Modified Mortars) intended for surface treatment such as screed or adhesive materials. For the design of adhesive and screeding substances (recommended for ETICS – External Thermal Insulation Composite Systems) use the alternative raw material sources, waste diatomaceous earth is used from the production at the firm LB MINERALS, s.r.o. (Czech Republic). This raw material is delivered in moist, therefore, it is necessary to dry it before the use and consequently mill it so to be able to replace milled limestone by the modified diatomaceous earth in the original formula.
