Abstract
This paper presents the effects of pozzolanic additives on the properties of Portland cement containing clay waste. Twelve different types of cement mortars were produced by adding fly ash and natural pozzolan (in the range of 5 % - 20 %) to ordinary CEM I 42.5 Portland cement containing 10 % and 15 % of clay waste. The cement mortars were subjected to compression and flexural tests. The durability of mortars were also evaluated by the measurements of the weight losses of the samples exposed to sodium sulfate or magnesium sulfate solutions. The scanning electron microscopy (SEM) analysis of the samples exposed to the sulfate solutions was also performed. The results showed that the clay waste could be used as cement additive up 15 % with the use of 20- 30 % pozzolanic material. Fly ash and natural pozzolan addition improved the resistance of mortars to sulfate attack.
