홈페이지논문 초록 (Abstract)
As the construction industry developed, the area of green area was reduced and the pavement was increased. As a result, the rainwater flow changes and problems occur. As a method of controlling the permeability of the permeable block, the permeability can be controlled according to the gradin of the upper layer aggregate. The properties of the upper aggregate grading were compared and analyzed. We also tried to improve the permeability by using the artificial permeable tube. The artificial permeable tube was used as the artificial aggregate, and the experiment was carried out according to the addition ratio. Density, water uptake, porosity, coefficient of permeability and flexural strength were selected as test items. The comparison of the aggregate grading of the upper layer and the properties of the addition of the artificial permeable tube were analyzed. As a result, the density decreased and the water absorption decreased as the aggregate grading increased. Also, porosity increased, permeability increased, and flexural strength increased. As the addition rate of artificial permeable tube increased, the density and water absorption decreased. Porosity and coefficient of permeability increased and flexural strength decreased. If the addition rate of the artificial permeable tube is adjusted according to the environment in which the permeable block is installed, a permeable block having a function suitable for the environment may be installed. The use of artificial permable tubes reduced the strength of the binder and cementing power. In addition, if waste plastics are recycled, they can be used as environmentally friendly materials.
