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;采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。

This is true as the brain and the fibrillating heart continue to consume atp and other energy sources 而腦和纖顫心臟繼續消耗atp和其他能源,這是確定的。
