Quick-setting and quick-hardening early-strength and high-strength pavement patching material and preparation method thereof
The invention discloses a quick-setting and quick-hardening early-strength pavement patching material, which is prepared from the following components in parts by mass: 2.4 to 33.7 parts of ordinary Portland cement, 9.6 to 38.4 parts of quick-hardening sulphoaluminate cement, 0 to 10.8 parts of mineral powder, 0 to 7.1 parts of fly ash, 0.2 to 0.5 part of dispersible latex powder, 0.2 to 0.5 part of modified fiber, 1.1 to 1.4 parts of water reducing agent, 11.1 to 12.3 parts of water and 37.9 to 38.6 parts of sand. The invention also discloses a method for preparing the quick-setting, quick-hardening, early-strength and high-strength pavement patching material, which comprises the following steps: stirring a part of raw materials, adding water and a water reducing agent, adding modified fibers, and stirring to obtain the quick-setting, quick-hardening, early-strength and high-strength pavement patching material. According to the invention, the advantages of the components are integrated, the respective defects are made up, rapid setting, rapid hardening and high strength are realized, and the requirement of rapid pavement repair is met; the preparation process is simple, and rapid construction is realized.
本发明公开了一种快凝快硬早高强路面修补材料，按质量份数计由以下成分制得：普通硅酸盐水泥2.4～33.7份，快硬硫铝酸盐水泥9.6～38.4份，矿粉0～10.8份，粉煤灰0～7.1份，可分散乳胶粉0.2～0.5份，改性纤维0.2～0.5份，减水剂1.1～1.4份，水11.1～12.3份，砂37.9～38.6份；本发明还公开了一种制备上述快凝快硬早高强路面修补材料的方法，该方法将部分原料搅拌后加入水及减水剂，再加入改性纤维搅拌得到快凝快硬早高强路面修补材料。本发明综合各成分优点的同时弥补各自的不足，实现了快凝快硬和高强度，满足了路面快速修补的需求；本发明的制备工艺简单，实现了快速施工。
