Badano zaprawy zawierające jako spoiwo mieszaninę cement, wapna i popiołu lotnego wapiennego oraz perlit i mielony piasek. Zmieniano udziały składników spoiwa i warunki dojrzewania zapraw, które obejmowały dojrzewanie w wodzie w temperaturze 20°C przez 28 dni i krótkie w 35°C oraz suszenie w 110°C. Badano wytrzymałość na ściskanie i zginanie gęstość pozorną oraz nasiąkliwość. Wyniki doświadczalne pokazały, że stosowanie wapna i popiołu lotnego zapewnia dobre właściwości zapraw, aczkolwiek najlepsze właściwości miały zaprawy zawierające w składzie spoiwa 50% cementu. Suszenie w 110°C zapewniało najlepsze właściwości zapraw.

The mortars from cement, lime and fly ash as binder and with pearlite and sand used as aggregate were produced. The varied combinations of binders were studied under different curing conditions. The samples of mortar stored in three different curing conditions (water curing of 28 days, water curing of 35°C, drying oven curing of 110°C) were tested for density, water absorption, compressive and flexural strength determination. Experimental results have shown that the use of lime and fly ash is providing positive results in terms of workability, density, water absorption and strength of mortars. However, the mortars containing 50% by mass of cement and 50% of lime and fly ash were showing generally the highest properties. The best curing condition in terms of mortars performance and time of production was oven drying at 110°C.
