PCE掺量与人工砂MB值的关系发布时间:2018/10/12 10:37:19 浏览次数:2043 | |
粘土类物质的层状结构对具有梳状结构的PCE分子具有强列的吸附,MB值超标会导致PCE掺量急剧上升。某些搅拌站对人工砂MB值操控不严,MB值忽高忽低,当MB值升高时,加大PCE掺量保持生产,当MB值下降时,PCE掺量回调不急时,导致混凝土离析、板结。导致堵管或质量事故的发作。
经多年的实践和实验研讨,以为亚甲蓝实验可有效地检测石粉中吸附功能力的凹凸。因此影响混凝土功能的不仅有石粉的含量,更有 MB 值,合理操控MB 值才是机制砂石粉用量操控的关键因素。配制亚甲蓝溶液要求用蒸留水,不然影响MB值准确性。
The layered structure of clay has strong adsorption on the comb-like PCE molecules, and the excessive MB value will lead to the sharp increase of PCE content. Some mixing stations do not strictly control the MB value of artificial sand, MB value suddenly high or low, when MB value rises, increase PCE dosage to maintain production, when MB value falls, PCE dosage adjustment is not urgent, resulting in concrete segregation and slagging. Cause blockage or quality accidents.
After years of practice and experimental study, it is considered that methylene blue test can effectively detect the concavity and convexity of adsorption function in stone powder. Therefore, not only the content of stone powder but also the value of MB affect the function of concrete. Reasonable control of MB is the key factor to control the amount of manufactured sand powder. The preparation of methylene blue solution requires steam water, otherwise it will affect the accuracy of MB value. 安徽泡沫混凝土官方网站:http://www.ahzjcl.com 最新内容:
