durability index中文什么意思
例句与用法
- Standard test method for aggregate durability index
集料耐久性指数的标准测试方法 - As we know , concrete structures in reality are always under various stresses or with microcracks of different width . so in this paper , compressive stress tensile stress and microcracks are introduced into water permeability and carbonation experiment , with the object to study the relationship between those factors and durability indexes . sem xrd and mip methods were also used to study the relevant mechanisms
由于实际工程中的混凝土结构均承受不同类型的荷载和带有不同宽度的微裂缝，故本文考虑选取外荷载引起的压应力对普通混凝土渗透性的影响，弯曲应力对砂浆、净浆碳化深度的的影响以及在带有裂缝状态下水泥基材料的渗透和自愈现象开展了部分实验研究，同时通过对混凝土、砂浆及净浆系列水泥基试件的碳化和渗透实验比较，从微观角度对碳化和渗透、自愈现象的一些机理也做了初步研究。
