In order to determine the level of destructions caused by the two chemically
aggressive environments; H2SO4 and Na2SO4, specimens were removed from the
curing mediums at the end of each observation period followed by compressive
strength test. The entire compressive strength tests were in conformity with BS
12390-3:2002. An average compressive strength of three cubes is considered as
the strength value of a particular batch. Indeed, during the process of compression
tests, it was observed that there was no significant aggressive destruction from the
chemical agents to cause an abrupt termination in the tests.
