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

本研究的目的在于提出多孔混凝土的施工标准，并建立一套质量控制体系。在提出施工标准的基础上，考察了多孔混凝土的耐久性，即考察了除冰盐（CaCl2）化学降解和汽车磨耗对多孔混凝土耐久性的影响。为实现质量保证体系，对试样取心方法、孔隙率和渗透率测量方法、养护方法进行了试验研究。此外，随着多孔混凝土排水路面在防灾领域的应用，多孔混凝土排水路面在城市防洪中得到了广泛的应用。

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.
