1)  CBR expansive rate
CBR膨胀率
1.
On the base of practical data in concrete project,conclusions have drawn as follows:CBR expansive rate has definite correlativity with total rate of swelling-shrinkage,and in engineering practice,CBR expansive rate could be used to determine the expansive behavior and classification index instead of total rate of swelling-shrinkage in the project of expressway.
通过具体工程的实际资料分析认为,对一特定地区的膨胀性土作为路基填料时,在一定条件下CBR膨胀率与胀缩总率存在一定的相关关系,在工程实践中可以用CBR膨胀率代替胀缩总率,作为高速公路路基填料膨胀性判别和分类指标。

膨胀率,膨胀系数
4)  expansivity [,ikspæn'siviti]
膨胀系数,膨胀率
5)  swelling number
膨胀指数;膨胀率
6)  expansion rate

Effects of salt crystallization of Na_2SO_4 and NaCl on concrete exposed to drying-wetting cycles were investigated by using index including concrete scaling amount,concrete expansion rate and strength loss rate,and chemical attack of concrete soaked in Na_2SO_4 and NaCl solutions was also measured.
以混凝土剥落量、膨胀率和强度损失率为评价指标,研究了干湿循环条件下Na2SO4和NaCl盐结晶对混凝土的破坏,并与在Na2SO4和NaCl盐溶液中浸泡的混凝土的化学侵蚀破坏结果进行对比。

CAS号:

性质:材料在发泡前的密度除以发泡制品的表观密度所得的比值。用以表示发泡材料的膨胀程度。特别是在二次发泡中,可表示出预发泡珠粒在发泡成型时所得制品的体积膨胀倍数。
