Establishment and application of construction standard and quality assurance system for porous concrete considering performance-based design

本研究的目的是提出多孔混凝土的施工标准，并建立一个质量控制系统。 除了施工标准的建议，多孔混凝土的耐久性进行了检查，即除冰盐（CaCl 2）的化学降解和汽车运行磨损的影响进行了研究。为了实现质量保证体系，对试件取芯方法、孔隙比和渗透率的测定方法以及养护方法进行了试验研究。 此外，作为其在防灾领域的应用，多孔混凝土排水路面被开发用于减轻城市中的洪水。

Purposes of the present study are to propose a construction standard and to establish a quality control system for porous concrete. In addition to a proposal of construction standard, durability of porous concrete was examined, i.e. the effects of chemical degradation by deicing salt (CaCl2) and wearing by run of car were investigated. In order to realize a quality assurance system, coring method of specimen, measuring method of void ratio and permeability, and curing method were experimentally investigated. Further, as its application to disaster prevention field, porous concrete drain pavement was developed for mitigating a flood in cities.
