Machine-sprayable dry-mixed mortar composition, machine-sprayable dry-mixed mortar as well as preparation method, application and use method of machine-sprayable dry-mixed mortar
The invention relates to the technical field of dry-mixed mortar, and discloses a machine-sprayable dry-mixed mortar composition, machine-sprayable dry-mixed mortar as well as a preparation method, application and a use method of the machine-sprayable dry-mixed mortar. The composition contains a first component of which the particle size is not greater than 0.075 mm and a second component of which the particle size is greater than 0.075 mm, the content mass ratio of the first component to the second component is 1: (1-3), and based on the total mass of the second component, the content of the second component with the particle size not smaller than 1.18 mm is 13-50 wt%. The dry-mixed mortar composition provided by the invention can be used for preparing a dry-mixed mortar product with good pneumatic conveying stability, and wet mortar prepared from the dry-mixed mortar has excellent pumping performance and is not easy to separate in the pumping process, so that the purpose of continuous pumping can be achieved.
本发明涉及干混砂浆技术领域，公开了一种可机喷干混砂浆组合物、可机喷干混砂浆及其制备方法、应用和使用方法。该组合物中含有粒径不大于0.075mm的第一组分和粒径大于0.075mm的第二组分；所述第一组分与所述第二组分的含量质量比为1:1‑3，且以所述第二组分的总质量为基准，粒径不小于1.18mm的第二组分的含量为13‑50wt％。采用本发明提供的干混砂浆组合物能够制备得到的气送稳定性良好的干混砂浆产品，将该干混砂浆制成湿砂浆后具有优异的泵送性能，泵送过程不易离析，能够实现连续泵送的目的。
