Title:
LIGHTWEIGHT POROUS BASE-LAYER BLOCK AND GROUND PAVEMENT STRUCTURE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2019/216711
Kind Code:
A1
Abstract:
The present invention relates to a lightweight porous base-layer block and a ground pavement structure comprising same. A porous base-layer block according to the present invention comprises: a synthetic resin structure having a mesh structure comprising multiple pores; and a porous concrete composition contained in the multiple pores of the synthetic resin structure, the porous concrete composition being formed by mixing bottom ash, recycled aggregate, cement, fly ash, and water and then agitating same. The porous base-layer block comprises a lightweight porous concrete composition inside the base-layer block and thus has improved rainwater permeability and temporary water-retaining capacity compared with the prior art. By using same, it is possible to store rainwater in the lower space of a ground pavement structure and to maintain underground water. Accordingly, it is possible to solve problems such as an urban heat island caused by an increasing non-water-permeable area inside an urban development space, degradation of urban water management environments resulting therefrom, and degradation of water quality.
