홈페이지논문 초록 (Abstract)
According to the test results, the principle conclusions are summarized as follows 1) When the replacement ratio of blast-furnace slag powder is increasing, slump flow become higher. but, high-range water reducer becomes less. generally, the more declining tendency the funneling time of type O shows, the more increasing replacement ratio of blast-furnace slag powder there is. 2) On one hand, at initial age, compressive strength is declined when replacement ratio of blast-furnace slag powder is increased; it shows same or higher values at age 28. on the other hand, when replacement ratio of blast-furnace slag powder is 70%, it shows lower level at age 28 comparing to plain concrete. also, elastic modulus generally shows similar level without the relation to replacement ratio of blast-furnace slag powder. 3) The durability of concrete using blast-furnace slag powder tends to be superior, but the carbonation of high performance concrete is no problem in this study scope in spite of depth of carbonation, as the replacement ratio increases.
