Abstract
The world's cement demand is anticipated to increase about 2.558$\%$ every year until the first half of the 21st century. To be closed the increase of cenment damand and simultaneously comply with the Kyoto Protocal, cement that gives less carbon dioxide(Co2) discharge should be urgently developed. If cement can be manufactured with industrial byproducts such as granulated blast furnace slag(GBFS), phosphogypsum(PG), and waste lime(WL) instead of clinker as its counterproposal, there would be many advantages including maximum use of these industrial byproducts for high value-added resources, conservation of natural resources and energy by omitting the use of clinker, minimized environmental pollution problems caused by Co2 discharge and reduction of the cost. So this study aims to solve the problems by manufacturing non-sintered cement.
