Marble has been effectively used as a
building material since the early civilization. The construction sector needs
to effectively utilize wastes that cause serious environmental problems around
the world. Structure of cementitious composites can be classified into micro,
meso, and macro levels. For cementitious matrix subjected to high temperature,
with the increase in temperature, physical and mechanical properties tend to
decrease at macro-level, internal structures deteriorate, and micro-defects
develop at micro and meso-levels. Studying the physical and mechanical
properties of cementitious matrix at elevated temperature helps us understand
the mechanisms of such deterioration or reduction in both physical and
mechanical properties. At elevated temperature, the compressive strength loss
of hardened cement paste composites comprising 80% of marble dust was 81% at
the end of 28-day curing period, and the reduction increased to 84% for the
hardened cement paste composites comprising 60% of marble dust. Its seems that
300 0C was optimum temperature for hardened marble cement paste
composites in that physical and mechanical properties above this level were
adversely affected.
