Novel high-durability traditional composite cementing material and preparation method thereof
The invention discloses a novel high-durability traditional composite cementing material, and a preparation method thereof. The preparation method comprises the following steps: I, weighing lime powder and metakaolin according to a ratio of 1: 1, and weighing cellulose fibers according to a ratio of cellulose fibers to ash of 1: 50; boiling glutinous rice slurry according to the requirement of concentration of 5%, slowly boiling the glutinous rice slurry with slow fire for not less than 4 hours, and stirring while boiling in the boiling process to ensure that glutinous rice mortar cannot be burnt until no lumps or other impurities exist; 2, cooling a cooked glutinous rice pulp to room temperature, then putting cellulose fibers into the glutinous rice pulp, and performing uniform stirring;and 3, pouring weighed lime and metakaolin into a container, firstly performing dry stirring uniformly, then pouring the glutinous rice slurry in the step 2, and performing stirring for at least 5 minutes until the mortar state is uniform. The novel high-durability traditional composite cementing material has the characteristics of high freeze-thaw resistance, high sodium salt corrosion resistanceand relatively high compression resistance.
一种新型高耐久性能传统复合胶凝材料及制备方法，步骤I：按照配比设计1：1称量石灰粉末和偏高岭土，按照纤维素纤维：灰＝1:50称量纤维素纤维；按照浓度为5％的要求熬制糯米浆，在熬制糯米浆时用文火慢熬不小于4小时，熬制过程中要求边熬边搅拌保证糯米灰浆不能糊锅，直至没有疙瘩或者其他杂质；步骤Ⅱ：将熬制好的糯米浆凉至常温然后将纤维素纤维放入其中搅拌均匀；步骤Ⅲ：将称量好的石灰和偏高岭土倒入容器先干搅拌均匀，然后将步骤Ⅱ中所述的糯米浆倒入搅拌至少5分钟至灰浆状态均匀即可。本发明具有高抗冻融性能、高抗钠盐侵蚀性能和较高抗压性能的特点。
