Zusammenfassung:In the smoothing of floors and walls with a smoothing plaster it has been a problem that extensive shrinking occurs on drying to such an extent that cracking and detachment of the smoothing layer from the base surface occurs. To counteract this problem, the invention provides a composition comprising hydrated calcium sulphate, especially CaSO4.1/2 H2O, cement and fly ash, in a weight ratio of 1:5-25:5-20 respectively, as bonding agents, aggregate, especially fine sand, and an agent for retarding reaction of the bonding agent. The invention includes this composition in dry and wet forms and its application to floors and walls.
