Usages of by-products in concrete production are
important subjects for sustainable development and industrial
ecology concepts. The usages as mineral admixtures or fine
aggregates improve durability properties of concrete and thus,
increase economical and environmental advantages for concrete
industry. Gains such as reducing the consumption of natural
resources and energy, increasing economical values of the byproducts
or wastes and preventing the waste depots are very
important for the world future. In recent years, for this reason, the
usages of by-products and wastes in concrete or cement industry have
become more important day by day. Thus, the production of
environmental friendly, durable and economical concrete has also
become the main target. In this study, the sulfate and high
temperature resistances of concrete mortar specimens produced with
ground granulated blast-furnace slag (GGBFS) and fly ash (FA)
replacing cement are investigated. Compressive strength test results
for all series related to types of cure types and materials, exposure
times for these cure types, temperatures and replacement ratios
(pozzolan content) are discussed. Consequently, the optimum
pozzolan contents are determined for producing sulfate and high
temperature resistant mortars.
