Figure gone, so we will look at the text under it
首先,很显然九种样品的延迟效应相当的小(图四)。2%含量样品的氢氧钙石沉淀时间比0.5%含量的氢氧钙石沉淀时间多一点点。相比于不加外加剂的水泥样品来说,2% 、C3的延迟时间也不过35min而已。此外, 2% 的C1到C4样品的热导率测量结果表明,不管引入什么外加剂,测量到的热导率的曲线走势是相似的,即对水泥水化的总体影响是一样的(图五)。
First, it is clear that nine kinds of samples delayed effects rather small (Figure IV). 2% calcium hydroxide content of the sample stone settling time less than 0.5% of the content of calcium hydroxide precipitate stone a little more time. Compared to the samples without admixture for cement, 2%, C3 35min delay time but also it. In addition, 2% of the samples C1 to C4 thermal conductivity measurements showed that no matter what the admixture introduced, the measured thermal conductivity trend curve is similar to that of cement hydration is the same as the overall impact (Figure 5 ).
在这个研究中,所用的每个外加剂有不同的分子量和独特的化学结构(如自然属性和取代基的内容)。研究表明,在研究的分子量范围内,分子量对水化的影响较小,不同分子量间最大的差距只有10min(图六)。因此,分子量不是控制水泥水化的关键参数。
In this study, the use of each additive with different molecular weights and unique chemical structure (such as natural attributes and content of substituents). Studies have shown that the molecular weight in the range of molecular weight less impact on the hydration of different molecular weights of the largest gap is only 10min (Figure VI). Therefore, the molecular weight is not the key parameters controlling cement hydration.
