省煤器膨脹板沖壓開裂原因分析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。Abstract : the result of experiment shows that und er the conditions of proper ai r - entraining, concrete with 20 % fly ash has excellent frost - resistance. the frost - resistance of concrete with 55 % fly - ash which is admixed with united expansive agent ( uea ) has been improved greatly. the frost - resistance of sulfate aluminate cement concrete with high volume of fly - ash is dramatically lower than that of silicate cement concrete with the same volume of fly - ash
