Original Abstract

The paper deals with the possibilities of preparation, processing and basic properties of silicate mass - cement paste using superabsorbent polymer (SAP). SAP is a relatively new additive, which is used in silicate mixtures, where in the early stages of hydration it absorbs excess mixing water and then releases it in the later hydration stages and thus contributes to the elimination of shrinkage cracks. The article deals mainly with the influence of recipe modification with regard to the use of energy by-product of high-temperature fly ash from brown coal combustion and the effects of its use on basic physical and mechanical properties, such as compressive strength, flexural tensile strength and bulk density.
