Long-service-life low-carbon iron aluminate cement concrete and preparation method of duct piece prepared from long-service-life low-carbon iron aluminate cement concrete
The invention belongs to the field of concrete products, and particularly relates to long-life low-carbon iron aluminate cement concrete and a preparation method of a duct piece prepared from the concrete. The preparation method comprises the following steps: spraying an oily release agent on a concrete duct piece mold for 12 hours in advance, spraying a water-based release agent on the concrete duct piece mold after 2 hours, and adding the aluminoferrite cement, the steam-curing-free functional material, the corrosion-resistant and wear-resistant reinforcing material, the fiber, the water reducing agent, the fine aggregate, the coarse aggregate and the water into a stirrer according to the formula ratio to obtain the aluminoferrite cement concrete for the duct piece. The stirred aluminoferrite cement concrete is poured into a mold in three times, then the duct piece concrete is cured with a curing agent, and finally the duct piece concrete is demolded and put into water for normal-temperature curing. According to the concrete duct piece, the wear resistance of concrete is improved, the duct piece is endowed with better washing resistance, the compactness of the duct piece is improved, the hydration rate of aluminoferrite water cement is regulated and controlled, the compactness of the concrete duct piece is improved, the corrosion resistance of the concrete is improved, and the durability of the concrete is improved.
本发明属于混凝土制品领域，具体涉及一种长寿命低碳铁铝酸盐水泥混凝土及所制管片的制备方法。先将混凝土管片模具提前12h先喷涂一道油性脱模剂，间隔2h后再喷涂一道水性脱模剂，将铁铝酸盐水泥、免蒸养功能材料、耐蚀耐磨增强材料、纤维、减水剂、细骨料、粗骨料及水按配方量投入搅拌机内，得到管片用铁铝酸盐水泥混凝土，将搅拌好的铁铝酸盐水泥混凝土分三次浇筑入模，再对管片混凝土用养护剂养护，最后脱模放入水中进行常温养护。本发明的混凝土管片提升了混凝土耐磨性，赋予管片更好的耐冲刷性，增加管片密实性，调控铁铝酸盐水泥水化速率，提高混凝土管片的密实性，提升混凝土耐蚀性能，改善混凝土耐久性。
