curing shrinkage 中文意思是什麼
curing shrinkage
解釋
加工損耗-
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。 -

With the very low water to cement ratio, rpc has ultra - high strength high ductility and low permeability. in this paper, the compressive strength of rpc can reach to a high point with the number approximately 135mpa. as illustrated from the study results, we can approve some fundamental conclusions : there are big effects on rpc with deferent kinds and properties of raw materials and deferent curing conditions ; stress - strain curve shows the process of destroy with rpc samples ; x - ray diffraction analysis indicates that heat treatment at temperatures 90 accelerate the hydration of rpc sharply, therefore, mechanical and microstructural properties of rpc are highly dependent on heat treatment ; it is believed that rpc materials have excellent resistance to chloride permeability ; during the heat treatment, the shrinkage of rpc developed quickly because of chemical reactions ; the rpc with slag mostly has the advantage of rpc without slag about resistance to solutions corrosion
研究結果表明：通過對rpc各組分摻量變化的研究，可以找到rpc的最優配合比；試件成型后的熱養護制度對rpc的性能影響巨大； rpc的抗壓應力?應變曲線可以反映出試件受破壞時微裂紋的擴展情況，剛纖維的摻入可以大幅改善rpc的韌性； rpc在成型后存在較大的收縮，而其中的化學收縮要遠遠大於乾燥收縮； rpc具有很強的抗氯離子滲透性能，漿體的密實度很高；通過x射線衍射實驗，可以發現rpc的膠凝體中ch晶體已經幾乎不存在，膠凝體主要由c - s - h凝膠和未水化水泥顆粒組成；在抗溶液侵蝕的實驗中，摻礦渣rpc的抗溶液侵蝕性能在絕大多數情況下要好於不摻礦渣試件，酸、堿溶液和浙江工業大學碩士學位論文摘要一些鹽溶液都會對rpc的結構產生侵蝕作用，但是機理各有不同。 -

From the research on hpec we can know that expansion property of high strength superplasticized expansive concrete shows obvious particularity compared with ordinary expansive concrete. when bfs is not put in, high strength superplasticized expansive concrete shows autogenous shrinkage in 1 day standard curing. and in 14 day ' s age e2 is less than half of middle strength superplasticized expansive concrete ' s with same csa dosage, and this shows expansion effect is confined more
對hpec混凝土的研究發現，與普通膨脹混凝土相比，高強流態膨脹混凝土的膨脹性能表現出明顯的特殊性，在不摻超細礦物質摻合料（磨細礦渣）時，高強流態膨脹混凝土標準養護1天時出現自收縮， 14天時其限制膨脹率不到相同csa摻量的中強流態膨脹混凝土限制膨脹率的一半，表現為膨脹效應受到更大限制。 -
