水胶比和粉煤灰对砼层面砂浆抗折抗压强度影响

摘要

通过实验对比分析了在相同水胶比下,粉煤灰掺量对层面处理砂浆抗压、抗折强度的影响,以及在相同粉煤灰掺量下,不同水胶比对层面处理砂浆的抗压、抗折强度的影响.通过对实验数据进行分析,得出了不同水胶比、不同粉煤灰掺量对碾压混凝土坝层面处理砂浆抗折和抗压强度的影响规律.%Through the comparison and analysis of the experiment,we find out the effect of fly ash content on compressive strength and flexural strength of layer-treated materials in the same water to binder ratio.We then compare the effect of wa-ter-binder ratio(0.39,0.42,0.45)on compression and flexural strength of layer-treated materials in the same amount of fly ash.After analyzing the experimental data,the influence of different water-binder ratio and different fly ash content on the mechanical properties of the RCC dam material was obtained.
