Alkali-activated green superfine high-performance composite admixture as well as preparation method and application thereof
The invention provides an alkali-activated green superfine high-performance composite admixture as well as a preparation method and application thereof, and belongs to the technical field of building materials. The alkali-activated green superfine high-performance composite admixture is obtained by selecting the superfine converter slag as a main component, adopting a specific alkali activator for excitation and matching with the use of a surfactant. When the alkali-activated green superfine high-performance composite admixture provided by the invention is used for replacing cement to prepare concrete, not only can the early and later compressive strength of the concrete be ensured, but also the alkali-activated green superfine high-performance composite admixture has the advantage of lower heavy metal dissolution amount, and meets the green and environment-friendly requirements of the contemporary industry on concrete admixtures.
本发明提供了一种碱激发绿色超细高性能复合掺和料及制备方法和应用，属于建筑材料技术领域。本发明通过选择超细转炉渣作为主要成分，采用特定的碱激发剂进行激发，同时配合表面活性剂的使用，获得了一种碱激发绿色超细高性能复合掺和料。将本发明提供的碱激发绿色超细高性能复合掺和料替换水泥制备混凝土时，不但可以保证混凝土的早期和后期抗压强度，而且还具有更低的重金属溶出量的优点，符合当代工业对混凝土掺合料绿色环保要求。
