The present invention provides a method for producing a permeation block using non-fired cement, which is mainly composed of blast furnace slag, which is an industrial by-product, and the permeation block thus manufactured. By using the by-product blast furnace slag as a main raw material, it is possible not only to prevent the environmental pollution caused by this, but also to manufacture the permeation block using such non-plastic cement, so that the permeability performance is kept constant even after elapse of time and the water permeability is improved. It can provide a manufacturing method of. |
