چکیده انگلیسی
Frost resistance of self-consolidating concrete (SCC) is very important in structures exposed to cold weather. On the other hand, Ground granulated blast-furnace slag (GGBS) as a waste material of industries can be replaced by cement in order to reduce cost of concrete production and also decreases the environmental Pollution. In this study, freeze-thaw resistance of SCC mixture prepared with w/c ratio of 0.44 and having cement as 418â¯kg/m3 was investigated in accordance with ASTM C 666 standard. In These Experiments Cement is replaced with 0%, 30%, 50%, 65% and 80% GGBS. Another SCC mixtures combining 50% GGBS with 5%, 10% and 15% silica fume were tested for Freezing-thawing resistance evaluation. Results of Experiments have shown that the more GGBS replaced with Cement, the lower frost resistance concrete has. It is also seen that increasing GGBS percentage in SCC reduces Compressive strength.
