Dry-mixed interface mortar
The invention provides dry-mixed interface mortar and a preparation method thereof. Hectorite and halloysite are added into a self-made machine-made sand to increase the viscosity of the sand, thereby having viscosity while forming a mortar framework, and enhancing the overall viscosity of the mortar. Fly ash is doped, so that the mortar has crack resistance. The hardness of the nano silicon oxide is high, and meanwhile, attachment points are increased. Silica sol is added into machine-made sand particles and cured to form a firm gel structure, and the viscosity is generated. The modified latex powder improves the adhesive property, has certain thickening property and permeability, and can permeate into two adhered wall bodies to shrink pores and cracks, thereby improving various properties such as surface hardness, impermeability, wear resistance and the like, and effectively preventing dry shrinkage and cracking of the mortar. Nano glass fibers improve the curing effect of the mortar. The coagulant adjusts the coagulation speed of the mortar, so that the density of the mortar is increased, and the strength is improved; The mortar is prevented from cracking due to the existence of a water-retaining agent component.
本发明提供了一种干混界面砂浆及其制备方法。其中，自制机制砂中添加了锂皂石、埃洛石用于增加砂的粘性，使其在构成砂浆骨架的同时，本身也具备粘性，增强砂浆的整体粘性。掺入粉煤灰使砂浆具有抗裂性。纳米氧化硅硬度大，同时增加附着点。硅溶胶加入到机制砂颗粒中，固化可成为坚固的凝胶结构，产生粘结性。改性乳胶粉使其粘结性能提高，同时有一定的增稠性和渗透性，通过渗透到黏连两面墙体内部，收缩其毛孔和裂缝，提高了表面硬度、抗渗、耐磨等各种性能，有效防止砂浆干缩开裂。纳米玻璃纤维，提高砂浆的固化效果。凝结剂调节砂浆的凝结速度，使砂浆的密度增大，强度提高；其中存在保水剂成分，防止砂浆开裂。
