Preparation method of mortar for highways in mountainous areas, forest areas and debris flow high-risk areas
The invention discloses a preparation method of mortar for highways in mountainous areas, forest areas and debris flow high-risk areas. The preparation method comprises the following steps: step 1, batching: weighing cement, silica fume, hydroxypropyl methyl cellulose, coal gasification fly ash, quartz sand, gypsum, high-strength fibers and a water reducing agent; 2, premixing cement, silica fume, hydroxypropyl methyl cellulose, coal gasification fly ash, quartz sand, gypsum and high-strength fibers, adding water, stirring, adding a water reducing agent, stirring at a low speed for 3-5 minutes, and stirring at a high speed for 6-8 minutes; pouring into a mold for solidification; 3, curing: performing steam curing, and obtaining a finished product after the curing is finished. According to the manufacturing method of the mortar, the mortar has very high compressive strength, so that even if a roadbed collapses, a road surface also has relatively strong supporting force, and the mortar is suitable for highways in mountainous areas, forest areas and debris flow high-risk areas.
本发明公开了一种用于山区、林区、泥石流高风险区公路的砂浆制备方法，包括如下步骤：步骤一、配料：称量水泥、硅灰、羟丙基甲基纤维素、煤气化飞灰、石英砂、石膏、高强度纤维和减水剂；步骤二、预先混合水泥、硅灰、羟丙基甲基纤维素、煤气化飞灰、石英砂、石膏、高强度纤维，加水搅拌，然后再加入减水剂低速搅拌3‑5min，再高速搅拌6‑8min；浇筑到模具中凝固；步骤三、养护：进行蒸汽养护，养护完毕得到成品。本发明的砂浆的制作方法，具有很高的抗压强度，因此即使路基出现坍塌，路面也还具有较强的支撑力，适用于山区、林区、泥石流高风险区的公路。
