灰粘作用 的英文怎麼說
中文拼音 [huīniánzuòyòng]
灰粘作用
英文
gleization-
The expansion agents can only make up the shrinkage to some extent, and the compensation effects would be reduced when the retardener and fly - ash are used. the expansion agents are not panaceas to avoid the shrinkage cracking as expansion can also reduce the concrete soundness. under bad curing condition, the polypropylene fibrillated film fiber can improve concrete ' s anti - crarking property, while the nominal steels have very unobvious effects. to reduce the concrete shrinkage thus avoid the cracking, the former factors must all be taken into account in concrete proportion design to develop sound concrete
研究結果表明，水泥的品種和用量是影響混凝土收縮值的主要因素之一，當混凝土中水泥用量超過470kg / m ~ 3時，混凝土的收縮值超過400 10 ~ （ - 6 ） ，在約束狀態下存在高開裂風險；採用細砂使混凝土單位用水量顯著提高，收縮值也大幅增加；優質粉煤灰總體上能抑制混凝土的收縮，以超量方式摻入其抑制作用更加明顯，但粉煤灰混凝土早期的粘聚性較差，應注意養護，以免失水產生龜裂；早強減水劑和緩凝減水劑都會使混凝土收縮值增加；膨脹劑只能補償混凝土部分收縮，同時受緩凝劑和粉煤灰的抑制，而且膨脹使混凝土的體積安定性增加了不確定因素，膨脹劑不是解決混凝土收縮裂縫的良方。On the basis of analysis on the pairwise action of cement paste, nanometer silica fume and clay, the paper proposes the reinforcement mechanism of the cemented soil stabilized with nanometer silica fume. the reinforcement mechanism includes cementation action of cement hydrate, ionic exchange and quadrate reaction of clay particle, pozzolanic effect, filling effect and cementation action of nanometer silica fume

用於內外墻抹灰、飾面磚板粘貼、水泥或石膏膩子批刮，並可作為粘接劑、界面劑使用，也可配製成細石混凝土用於結構加固和維修工程。It is made of sand, cement and lightweight aggregate, etc. some of the lightweight aggregates include pumice, stuff, expanded clays ( haydite ), etc. lightweight aggregate concrete can provide the same strength as the normal concrete with less weight
輕骨料混凝土是一種用量較大的新型混凝土，其密度在850kg m ~ 3至1950kg m ~ 3之間，由粘土陶粒，粉煤灰陶粒等粗骨料以及常用的砂，水泥，水等材料製作而成。Based on the principles of designs of self - compacting and light aggregate concrete mix, sclc of lc30 - lc50 was developed by using absolute volume method. the main factors affecting the workability of sclc were studied by adopting the modified l - 800 fluidity instrument. the results indicate that the key techniques insuring good workability of sclc are about 30 % first - grade fly ash, about 50 % volume sand ratio, 2 % ~ 6 % dosages of silicon fume and compounded superplasticicizers with viscous ingredient
採用改進l - 800流動儀，研究了影響lc40自密實輕骨料高性能混凝土工作性的主要因素，結果表明：粉煤灰摻量保持30左右，硅灰摻量為2 6 ，體積砂率為50左右和摻加具有粘塑組分的復合高效減水劑是保證sclc拌合物具有較好工作性的關鍵。Soils : investigation and testing - soil treated with hydraulic binder, possibly combined with lime, for use as a selected fill - part 1 : definition - composition - classification
