Permeable concrete "TK Tomicon" places emphasis on "consideration for the natural environment" in product development, using an inorganic calcium carbonate-based solidifying agent as an admixture. The admixture reacts with Portland cement to produce smooth and dense hydration products, thereby minimizing the leaching of cement components into water after application. Furthermore, the cement paste after the addition of the admixture exhibits excellent adhesion, firmly bonding the aggregates together, and its high viscosity controls clogging due to drooping, resulting in significantly enhanced permeability. During construction, the admixture is added to the ready-mix concrete truck upon arrival at the site, mixed, and then discharged for pouring, allowing for easy application without the need for special machinery. 【Features】 ○ Available in 12 color variations, allowing for harmony with various residential exteriors and gardens. ○ Can be installed without worrying about water gradients. ○ By increasing the permeable layer (including the underlying crushed stone), it can reduce the need for drainage facilities such as U-shaped gutters.
