摘要
本文着重讨论了试件脱模时间、不同水泥对砂浆限制膨胀率试验结果的影响 ,试验表明 ,不同的脱模时间 ,不同的水泥及其出厂时间 ,试件的限制膨胀率亦不同。在现有的标准规定下 ,找出一个脱模的时间范围 ,文中对造成这一结果的原因进行了初步分析 ,供读者共同讨论。
? This text discasses mainly about the influence of the stripping time of test specimen and different cement on experimental result of confined expansion ratio of mortar. Tests indicate that different stripping time, different cement and different manufacture date makes different confined expansion ratio of test specimen. According to present standard this paper finds out the range of stripping time and makes a initial analysis of the reasons about this result.This article is offered to readers for discussing together. 〔
