Abstract
Now, the carbon dioxide discharged from the cement industry in our country forms about 4％ of total amount of discharge. So, as part of the steps to deal with the global warming issue, it is a very effective measure to reduce the amount of the cement clinker which discharges a lot of carbon dioxide at the time of manufacturing it. This study aims to reduce environmental load and new blast furnace cement type A with low shrinkage property was developed. The performances of this new blast furnace cement type A is equal or superior to conventional ordinary portland cement.
In this paper, the compressive strength and crack resistance of concrete using this new cement were studied.
As a result, it is showed that concrete using this new cement has equally compressive strength as compared with concrete using ordinary portland cement, and it is found that crack resistance of the concrete is improved.
