  1. 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。
  2. The characteristic of chemical grouting material should combind with construstion method directed by the theories, it is necessity guarantee for the good result in some special cases. by cw series material, various complicated engineerings have been successfully handled, such as the treatment of concrete fine cracks in three gorges project ( tgp ), foundation reinforcement to the fault in in three gorges project ( tgp ), and the seepage control and reinforcement for the dam base of jiangya hydropower - station. these illustrations are provided to proof the advantages of modified epoxy resin and its technique

  3. Cause and repair of cracks occured in cement concrete pavement slabs

    水泥混凝土路面板裂縫產生的原因與修補技術
  4. To significantly improve both strength and durability of repair interfacial layer between old and new concrete, two attempts were firstly put forward in this thesis : ( 1 ) a kind of new modified primer would be produced by introducing shrinkage reducing admixture into cement mortar, which may both reduce the shrinkage of the interfacial layer, and lessen the content of large crystal in the repaired interface layer, accordingly, remarkably increase the van der waals force of interfacial layer

    為大幅度提高新老混凝土修補界面層的強度和耐久性，本文首次提出並實現兩個設想： （ 1 ）以國產減縮劑為外加劑，配製新型改性水泥砂漿界面劑。該界面劑既能減少界面層宏觀干縮裂縫，又不增加大晶體，使界面層形成密實的微細觀結構，顯著提高粘結界面層內晶體間的范德華力。
