Roof anti-cracking protection layer and construction method
The invention discloses a roof anti-cracking protective layer and a construction method, and solves the technical problems that roof concrete in the prior art is easy to crack and deform in dry and wet, temperature and structural changes and is transmitted to a flexible waterproof layer, and meanwhile, sunlight and air oxidation can intensify the destructive effect of a flexible waterproof material. The high-strength concrete comprises the following components: 150-250 parts of cement; 50 to 80 parts of fly ash; 20 to 50 parts of mineral powder; 220 to 350 parts of broken stone; 5-10 parts of a water reducing agent; 5-8 parts of polypropylene fiber; and 60 to 120 parts of water. When the high-impermeability and anti-cracking protective layer is poured, an interface strengthening process, namely an impressing process, is adopted, so that an interface strengthening effect can be generated, the problem that the interface bonding strength of the functional gradient concrete functional layer is reduced can be effectively solved, and inhabitation places which are continuously damaged and expanded by an erosion medium in the using process due to the weak interface area are reduced.
本发明公开了一种屋面抗渗裂保护层及施工方法，解决了现有技术中屋面混凝土在干湿、温度和结构变化中易开裂变形并传递到柔性防水层中，同时日照和空气氧化会加剧柔性防水材料的破坏作用的技术问题。它包括水泥：150～250份；粉煤灰：50～80份；矿粉：20～50份；碎石：220～350份；减水剂：5～10份；聚丙烯纤维：5～8份；水：60～120份。本发明浇筑高抗渗抗裂保护层时，采用界面强化工艺一压印工艺，可产生界面增强效应，能有效地解决功能梯度混凝土功能层界面粘结强度降低的问题，减少界面区薄弱造成的使用过程中成为侵蚀介质不断破坏、扩容的栖身场所。
