The purpose of this study is to identify the possibility of developing the 100% Recycled-resources Absorbent-Pervious Alkali-activated Blocks using both the alkalli-binder and the recycled aggregate. In addition, It established a test method such as Void ratio, compressive strength, coefficient permeability, absorption, and evaporation. As a result, an alkali-activated using recycled aggregate block was able to manufacture an 24 MPa class absorbent-pervious blocks with a liquid type sodium silicate and early high temperature curing. In this case, water-holding capacity, absorption and relative absorption were more effective than the natural aggregates. In conclusion, Absorbent-pervious alkali-activated Block Using recycled aggregate has a surface temperature reducing effect of approximately 10 % compared to ordinary concrete block.
