Alkali-activated slag mortar mixed material and preparation method thereof
The invention belongs to the technical field of cement-based composite materials, and particularly relates to an alkali-activated slag mortar mixed material and a preparation method thereof. The alkali-activated slag mortar mixed material comprises alkali-activated slag mortar and a mixture of rigid fibers and tetrasodium hydroxyethylidene diphosphonate. The rigid fibers have the effects of crack resistance, reinforcement and toughening, and are beneficial to improving the mechanical properties of the alkali-activated slag mortar. Meanwhile, the tetrasodium hydroxyethylidene diphosphonate can delay the setting time of the alkali-activated slag mortar and improve the flowing property and rheological property of the alkali-activated slag mortar, and the improvement of the rheological property can further improve the distribution and orientation of the rigid fibers in the alkali-activated slag mortar, so that the promotion effect of the rigid fibers is better exerted. Therefore, the alkali-activated slag mortar mixed material provided by the invention has good working performance and mechanical properties, can meet the requirements of actual construction and the requirements on material strength, and has a good application prospect.
本发明属于水泥基复合材料技术领域，具体涉及一种碱激发矿渣砂浆混合材料及其制备方法。本发明碱激发矿渣砂浆混合材料包括碱激发矿渣砂浆与刚性纤维和羟基亚乙基二膦酸四钠的混合物。刚性纤维具有阻裂、增强增韧的作用，有助于改善碱激发矿渣砂浆的力学性能。同时，羟基亚乙基二膦酸四钠可以延缓碱激发矿渣砂浆的凝结时间，改善碱激发矿渣砂浆的流动性能和流变性能，而流变性能的改善又能进一步改善刚性纤维在碱激发矿渣砂浆中的分布和取向，从而更好地发挥刚性纤维的促进作用。因此，本发明碱激发矿渣砂浆混合材料具有良好的工作性能和力学性能，可满足实际施工的需求和对材料强度的需求，应用前景良好。
