expansion admixture 中文意思是什麼
expansion admixture
解釋
膨脹劑-
The results indicate that the strength of mortar with early - strength admixture and uea expansion admixture will improve largely
結果表明，摻有早強型減水劑和uea膨脹劑的砂漿的強度有了較大程度的提高。 -
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
將摻加了u型微膨脹劑的砂將作為錨桿水下膠結物，由錨桿齡期10天的抗拔試驗結果可以看出，這種膠結物的握裹效果很好。 -
Some problems on the application of expansion admixture and compensated shrinkage concrete
耐磨抗沖擊補償收縮混凝土的研究 -
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
在實際使用中，膨脹劑類型、摻量及其使用條件對混凝土的主要性能影響很大，現有的膨脹劑存在著實際摻量較大、混凝土強度及耐久性發展與膨脹劑的膨脹速率不協調、膨脹效能如何評價、鈣礬石aft相延遲性反應（ def ）等一系列問題，而目前國內外這方面的研究成果較少。 -
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
本文試圖從膨脹劑不同摻量研究其對混凝土和砂漿主要性能的影響，進行了一系列宏觀力學性能試驗研究；利用差熱分析（ dta ） 、掃描電子顯微鏡（ sem ）等分析手段對鈣礬石等水化產物的結晶和生成量、形貌特徵進行微觀分析；並採用復合方法摻加新型膨脹組分對硫鋁酸鹽類膨脹劑（ uea ）進行了改性試驗研究，根據多因素模糊綜合評價方法就各類膨脹劑的主要性能進行綜合評價，得出摻加新型膨脹組分pt的膨脹劑性能較優，取得了明顯的效果。 -
It has a good compensation to shrinkage, and can improve the anti - cracking and anti - penetrating performance of concrete. it is often added to concrete to produce expanding concrete or the anti - cracking and anti - penetrating concrete, which are widely used in such engineering as waterproofing, anti - penetrating, mending etc. the expansion admixture include at present sulphoaluminate such as uea, ea - l etc ), calcium oxide, and some composite expansion admixtures
混凝土膨脹劑在普通混凝土中可抵消干縮或溫度降低引起的拉應力，起到良好的補償收縮作用，能提高混凝土的抗裂防滲能力，常用於配製膨脹混凝土或抗裂防滲混凝土，廣泛地應用於防水、抗滲、修補等工程中。
