High-activity stone powder-based concrete admixture
The invention discloses a high-activity stone powder-based concrete admixture which comprises a mixture A, a mixture B and a mixture C. The mixture A comprises a water reducing agent, activated clay powder or montmorillonite powder and a surfactant, the mixture B comprises an early strength agent and a thickening agent, and the mixture C comprises a cosolvent and a defoaming agent. Free water is reduced by utilizing the moisture absorption effect of the activated clay powder or montmorillonite powder, so that the influence of a humid environment on the humidity of the concrete mixture is reduced. The strength of the concrete is improved by adding the water reducing agent, the early strength agent and the defoaming agent, and meanwhile, by adding the components such as the surfactant, the thickening agent and the cosolvent, the fusion effect of all the components of the admixture is improved, the stirring and mixing time is shortened, the concrete is more viscous and easy to form, bubbles are reduced, and the strength is further improved.
本发明公开了一种高活性石粉基混凝土外加剂，包括混合物A、混合物B和混合物C，所述混合物A包括减水剂、活性白土粉末或蒙脱土粉末、表面活性剂，所述混合物B包括早强剂和增稠剂，所述混合物C包括助溶剂和消泡剂。本发明利用活性白土粉末或蒙脱土粉末的吸湿作用减少游离水，从而起到降低潮湿环境对混凝土混合料湿度的影响。本发明通过添加减水剂、早强剂和消泡剂，提高混凝土的强度，同时通过加入表面活性剂、增稠剂、助溶剂等成分，增加了外加剂各组分之间溶合的效果，缩短了搅拌混合的时间，使混凝土更加粘稠，易于成型，鼓泡减少，强度得到进一步的增加。
