expansion admixture meaning in Chinese
膨胀剂
Examples
- Some problems on the application of expansion admixture and compensated shrinkage concrete
耐磨抗冲击补偿收缩混凝土的研究 - The results indicate that the strength of mortar with early - strength admixture and uea expansion admixture will improve largely
结果表明，掺有早强型减水剂和uea膨胀剂的砂浆的强度有了较大程度的提高。 - This kind of adglutinate mixed with u expansion admixture can grip anchor bolts tightly even underwater , as can be seen from the pull - out type tests for anchor bolts when the mortar age is over 10 days . ( 2 ) the author lays the supporting piles as a arched shape
将掺加了u型微膨胀剂的砂将作为锚杆水下胶结物，由锚杆龄期10天的抗拔试验结果可以看出，这种胶结物的握裹效果很好。 - In practical uses , the major performances of concrete are associated with the quantities , types and the service conditions of the expansion - admixture . the expansion admixtures of concrete available at present still have many shortcomings , such as the greater quantities required , the non - relevance between developments of concrete strength and durability and expanding speeds of expansion admixture , the evaluation of expanding effects , the def of aft etc . unfortunately , few achievements in these aspects have been obtained all over the world
在实际使用中，膨胀剂类型、掺量及其使用条件对混凝土的主要性能影响很大，现有的膨胀剂存在着实际掺量较大、混凝土强度及耐久性发展与膨胀剂的膨胀速率不协调、膨胀效能如何评价、钙矾石aft相延迟性反应（ def ）等一系列问题，而目前国内外这方面的研究成果较少。 - 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。
