一、引言近年来,为了满足建筑工业化的需要,浮石混凝土发展很快,除用做砌块以外,比较广泛应用在钢筋混凝土构件中,其中有民用和工业墙板、楼板、屋面板以及门窗过梁等.一般反映良好,但人们对浮石混凝土的耐久性,特别是碳化和钢筋锈蚀方面的问题比较关注.众所周知,对钢筋混凝土构件,除应在结构上具有一定的安全度外,还要考虑耐久性的要求,才能保证建筑物达到予期 I. INTRODUCTION In recent years, in order to meet the needs of building industrialization, pumice stone concrete has developed rapidly. Apart from being used as a block, it is widely used in reinforced concrete components, including civil and industrial wall panels, floors, roof panels and doors and windows. Liang et al. generally reflect well, but people are more concerned about the durability of pumice stone concrete, especially carbonization and corrosion of steel bars. It is known that for reinforced concrete structures, in addition to the structure should have a certain degree of safety, but also to consider Durability requirements ensure that the building will reach its expected date
