However , the setting and hardening time of the concrete , the mortar influences the test results obviously 混凝土?水泥砂浆?环氧树脂砂浆的凝结硬化时间长短对测试结果有比较显著的影响。
The influence of different technological conditions including ph . mass ratio of gelation , the time of gelation , as well as the hardening time on yields of microcapsulation the efficiency of encapsulation were studied respectively . the microencapsulation condition were also optimized 采用光学显微镜、 tem 、 sem 、激光粒度分析仪研究了微胶囊的表面形态、包覆效果和粒径分布;采用tg和dsc研究了微胶囊的热稳定性和储热调温效果。
3 . based on the bond test for 33 concrete specimens and gfrp and bending test for 15 beams strengthening with gfrp , surface preparation of concrete , type of epoxy adhesives , thickness of adhesives , hardening time of adhesives , cure condition after strengthening are considered , and the effect on concrete structures strengthening with gfrp causing by construction behavior was analyzed . 4 根据gfrp片材加固混凝土结构在施工中常涉及到的一些相关因素,如混凝土基层表面处理情况、所选用的粘结剂类型、涂抹粘结剂的厚度、加固的方式以及养护状况,进行了33个混凝土试件与gfrp片材的剪切粘结试验,并进行了采用gfrp片材加固的15根混凝土梁的抗弯试验,分析了与施工性能相关的因素对gfrp片材加固混凝土结构效果的影响。
