1)  electrical resistivity
水化电阻率
1.
The results show that when 30% cement are replaced by CFBA,in the earlier hydration period,the electrical resistivity increase,and it is directly proportional to the fineness of CFBA;CFBA retard the setting time of cement,but grinded CFBA curtail it;CFBA increase the hydration heat of early age pastes of cement,and grinded CFBA are higher than original ones.
为了探讨固硫灰作水泥掺和料的水化行为,本文研究了不同细度固硫灰替代部分水泥时胶凝体系1d水化电阻率和水化放热的变化,分析了不同细度固硫灰对水泥早期水化行为的影响。

产水电阻率
4)  relative change of resistance
电阻变化率
5)  ratio of resistance variety
电阻率变化
6)  fractional change in electrical resistivity
电阻率变化率
1.
The fractional change in electrical resistivity of cement-based materials with vol 25% nickel powder goes up to 40% and 35% under single compressive loading and within elastic regime respectively,which indicates these materials possess favorable piezoresistivity.
掺量25%的镍粉复合水泥基材料一次加载至破坏,电阻率变化率最大可达40%,弹性阶段电阻率变化率可达35%以上,具有良好的压敏性;且其压敏性基本不受加载速率和试件偏压的影响。

性质:水分子的正、负电荷中心并不重合,是偶极子。它又有很强的氢键作用,故水有特殊的结构。电解质溶解时其离子的静电力破坏了水的结构,在离子周围形成水化层。这是一种溶剂化过程,物质的溶解过程必定伴随有溶剂化。许多物质能溶于水,是与水有很强的水化能力分不开的。
