水泥粉煤灰混合砂浆应用技术研究

Mixed fly ash cement mortar applied technology research

利用粉煤灰替代石灰膏配置混合砂浆,通过大量的试验数据对比,找出满足砂浆和易性和强度满足要求的合理掺加比例,并在标准养护和自然养护条件下,分别检测砌筑砂浆的保水性、流动性和不同龄期的强度,符合规范和使用要求,得出粉煤灰替代石灰膏后对混合砂浆抗压强度的影响,总结了水泥粉煤灰砂浆的强度增长规律。另外,找出在混合砂浆中粉煤灰最适宜的掺加比例和强度变化的规律。

Alternative use of fly ash mortar of lime paste mixed configuration, a large number of experimental data by contrast,mortar and easy to identify and meet the strength to meet the reasonable requirements of mixing ratio, and the standard conservation and the conservation of natural conditions, were detected Mortar retention and mobility of the strength of the same age period, in line with norms and use requirements, lime paste substitute fly ash obtained after the compressive strength of mortar mixed, summed up the fly ash cement mortar strength of growth.In addition, in the mixed mortar to identify the most suitable fly ash mixing ratio and the change of intensity.
