Self-compacting concrete mix proportion design method
The invention provides a self-compacting concrete mix proportion design method. The method comprises the following steps: S1, measuring and/or calculating performance parameters of raw materials; s2, an excess sand layer model and an excess slurry model are constructed, a parameter ts is determined through the excess sand layer model, the ts represents the thickness of an excess filling sand layer on the surface of the coarse aggregate and is used for reflecting the rolling effect of a solid-phase material under different fine aggregate proportions, and correlation between the coarse aggregate volume proportion and the fine aggregate volume proportion is achieved; a parameter tp is determined through an excess slurry model, and tp represents the thickness of an excess slurry filling layer on the surfaces of the coarse aggregate and the fine aggregate and is used for reflecting the lubricating effect of the self-compacting concrete under different slurry material proportions, so that correlation among the volume proportions of the coarse aggregate, the fine aggregate and the slurry is achieved; and S3, determining the mix proportion of the self-compacting concrete. According to the invention, the mix proportion of the self-compacting concrete can be dynamically adjusted, so that the requirements on raw materials and construction environment changes in different regions are met.
本发明提供了一种自密实混凝土配合比设计方法，包括步骤S1、测定和/或计算原材料的性能参数；步骤S2、构建过剩砂层模型以及过剩浆体模型，利用过剩砂层模型确定参数ts，所述ts表示粗骨料表面的过剩填充砂层厚度，用于反映固相材料在不同细骨料占比下的滚动效应，实现对粗骨料和细骨料体积比例间的关联；利用过剩浆体模型确定参数tp，所述tp表示粗骨料和细骨料表面的过剩浆体填充层厚度，用于反映自密实混凝土在不同浆体材料占比下的润滑效应，实现对粗骨料、细骨料和浆体体积比例间的关联；步骤S3、确定自密实混凝土配合比。本发明能够实现动态调整自密实混凝土配合比，进而适应了对不同地域原材料和施工环境变化的需求。
