Effect of Sulfates on the
Properties of Terrazzo Tiles
Abbass Salim Abbass Ali Hasson Nahhab
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 .
