膨胀组分 meaning in English
expansion component
Examples
- The major performances of concrete and mortars , which are mixed with different quantities of expansion admixtures under the same mix proportions , are studied systematically and deeply in this work . sulphoaluminate mixed with a type of new expanding component by use of the composite methods are studied in the laboratory , and some achievements have been obtained . the service conditions , the characteristics and the shortcomings of expansion admixture in the concrete engineering are analyzed and summarized based on literatures , and the expanding mechanism of concrete is discussed
本文试图从膨胀剂不同掺量研究其对混凝土和砂浆主要性能的影响，进行了一系列宏观力学性能试验研究；利用差热分析（ dta ） 、扫描电子显微镜（ sem ）等分析手段对钙矾石等水化产物的结晶和生成量、形貌特征进行微观分析；并采用复合方法掺加新型膨胀组分对硫铝酸盐类膨胀剂（ uea ）进行了改性试验研究，根据多因素模糊综合评价方法就各类膨胀剂的主要性能进行综合评价，得出掺加新型膨胀组分pt的膨胀剂性能较优，取得了明显的效果。
