Waterproof protection material for surface layer of prefabricated outer wall and manufacturing method of waterproof protection material
The invention relates to a waterproof protection material for a surface layer of a prefabricated outer wall and a manufacturing method of the waterproof protection material. The waterproof protection material comprises the following components in parts by weight: 200-300 parts of cement, 15-30 parts of silica fume, 50-80 parts of mineral powder, 500-800 parts of machine-made sand and 15-35 parts of an additive. The manufacturing method comprises the following steps: firstly, automatically metering and proportioning all the components; sequentially adding the machine-made sand, the cement, the silica fume, the mineral powder and the additive into a stirrer; conducting stirring at low speed at first and then at high speed; after the stirring is completed, detecting uniformity, consistency and fluidity, and manufacturing a test block for testing waterproof effect, the shrinkage of mortar and bonding strength; and applying the obtained product to practical use after detection is qualified. According to the invention, erosion of water vapor to concrete is effectively blocked, the carbonization speed of the concrete is reduced, failure phenomena such as cracking, peeling and falling off in a later period are avoided; and thus, multiple brushing in the later period is effectively avoided or reduced, operation and maintenance cost is reduced, and the service life of a prefabricated concrete component is prolonged.
本发明涉及一种装配式预制外墙面层防水保护材料及制作方法，包括如下重量份的组份：水泥200～300份，硅灰15～30份，矿粉50～80份，机制砂500～800份，添加剂15～35份；该制作方法包括先对各组份自动计量配料；向搅拌机内依次加入机制砂、水泥、硅灰、矿粉、添加剂；先慢速后高速搅拌；搅拌完成后，进行均匀度、稠度、流动度的检测，并制作试块进行防水效果、砂浆的收缩性、粘结强度的测试；检测合格后方可使用；本发明有效阻隔水汽对混凝土的侵蚀，降低了混凝土的碳化速度，没有后期的开裂，起皮脱落等失效现象发生，一方面，有效避免或减少了后期的多次涂刷，降低运维成本，另一方面，提高了混凝土预制构件的寿命。
