Corrosion-resistant reinforced concrete pipe and preparation method thereof
The invention discloses a corrosion-resistant reinforced concrete pipe and a preparation method thereof. The corrosion-resistant reinforced concrete pipe comprises the following raw materials in partsby weight, 10-20 parts of sand grains, 20-30 parts of Portland cement, 10-20 parts of yellow sand, 5-10 parts of inorganic silicon waterproof anti-crack mortar, 5-10 parts of a waterproof anti-crackcement enhancer, 5-10 parts of rock powder, 5-10 parts of polyacrylamide, 10-20 parts of redispersible latex powder, 5-10 parts of alkali-resistant glass fibers and 5-10 parts of ultra-strong silica fume. Based on the fact that a traditional steam pool is used for moistening and is not influenced by external temperature, the operation difficulty of a steam curing process is reduced, and the qualification rate of the reinforced concrete pipe is improved, namely, the reinforced concrete pipe with the specification of inner diameter * wall thickness * length (phi 500 * 50 * 200) mm is obtained, the water pressure in the compressive strength of the obtained reinforced concrete pipe is inspected to be larger than or equal to 0.03MPa, water tightness is achieved, the strength of concrete is larger than or equal to C30, and the crack load is grade-2 and larger than or equal to 75KN/m.
本发明公开了一种抗腐蚀型钢筋混泥土管材及其制备方法，包括以下重量份原料：沙粒10‑20份、硅酸盐水泥20‑30份、黄沙10‑20份、无机硅防水抗裂砂浆5‑10份、防水抗裂水泥增强剂5‑10份、岩石粉5‑10份、聚丙烯酰胺5‑10份、可再分散乳胶粉10‑20份、抗碱玻璃纤维5‑10份和超强微硅粉5‑10份，利用传统蒸汽池温润、不受外界温度影响，减少了蒸汽养护工艺的作业难度，提高了钢筋混凝土管材的合格率，即规格内径*壁厚*长度(φ500*50*200)mm的钢筋混凝土管材,检验所得该钢筋混凝土管材抗压强度内水压力≥0.03MPa不透水，混凝土的强度≥C30，裂缝载荷为二级≥75KN/m。
