Abstract 
         An experimental study was conducted to investigate the effect of total sulfates in the mix on the properties of terrazzo tiles . These properties are modulus of rupture , ultrasonic pulse velocity , surface absorption and total absorption .Four levels of total SO3 content in the mix were investigated , namely 4 , 6 , 8 and 10 % by weight of cement .
           Test results indicate that there is an optimum SO3 content in which the ultrasonic pulse velocity is maximum and total absorption is minimum for all ages considered in this research .This optimum SO3content was found to be 6 % by weight of cement giving increase in ultrasonic pulse velocity ranging from 4.65 to 13.96 % and a decrease in total absorption from 0.163 to 3.17 % . On the other hand , increasing the percentage of  SO3has the effect of decreasing the modulus of rupture .For example , at the 6 % sulfate content , the decrease in modulus of rupture is varied from 12.7 to 39 % .
The analysis of the test results also shows that the properties of terrazzo tiles are deteriorated by increasing the period of curing for mixes of high  SO3content .
