The effort spent on careful grading, mixing and compaction of concrete will be largely wasted if the concrete is badly cured.
如果混凝土養護得很差,那麼在精心選定混凝土的級配、拌和和密實成型上所耗費的精力將是徒勞無益的。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。Slow, careful curing of the concrete improves the hydration of the cement.
混凝土的緩慢而精心的養護可以改善水泥的水化作用。Shotcrete - rock bolt support and concrete lining are important parts of timbering structures in modern tunnel construction, and there are also essentials for natm. the intensity difference of concrete is big because of the big randomicity at the aspects of material, metage of additive, mix round, ratio of water and lime, spray construct and water maintain
由於噴射混凝土和二次襯砌在拌和料、外加速凝劑的稱量、拌勻以及水灰比的配比、在噴射作業及灑水養護上都存在著很大的隨機性,其強度的差異也較大。Ill 6. regularity of concrete petrography changing with temperature, standing time, cooling and curing process was studied by x - ray diffraction analysis. microscopic mechanics relative to macroscopic phenomenon after fire was discussed

對自然養護的製品水化過程分析的研究表明,尾礦和石英砂表面對於水化產物的主要影響是利於晶胚生成的「基底作用」 ,基本不參與化學反應,而蒸壓溫度和壓力對低硅尾礦加氣混凝土水化產物的結構、形態有著明顯的影響,導致兩種製品的抗壓強度有明顯差別。After bfs is put into high strength superplasticized expansive concrete ( substituted for cement ), autogenous shrinkage does n ' t appear in 1 day standard curing, and e2 in 14 day ' s age is higher than that of high strength superplasticized expansive concrete without bfs in the same age
