| Summary: | 碩士 === 正修科技大學 === 營建工程研究所 === 98 === Course of the study found, adding the proper amount of furnace slag, fly ash, limestone and other reference material, the compressive strength at early ages (3 to 7 days age) of the performance driven by the rapid upgrade of furnace slag. After the age of the overall strength of the performance also in the sustainable maintenance ,served with an appropriate amount of limestone powder, not only can reduce the bleeding of concrete water and increase the performance of concrete ,the overall strength in early age can also be micro-upgrade ,compressive strength will not allow to add limestone powder while lost from changes；Late age at the time of the pozzolanic effect of fly ash is generated there, so the durability of concrete will substantially improve.
In terms of cement consumption for the whole 50% of cement weight ,the best ratio of the compressive strength is [Cement50%: Slag37.5%: FA6.25%: LSP6.25%].Cement consumption for the whole 75% of cement weight,the best performance ratio of compressive strength is [Cement75%: Slag18.75%: FA3.13%: LSP3.13%] .
