Lightweight high-strength hydraulic engineering concrete and preparation method thereof
The invention discloses a preparation method of lightweight high-strength hydraulic engineering concrete. The preparation method comprises the following steps: preparing a pretreated cement base material; adding water into sepiolite powder in a stirring state, adding octadecyl trimethyl ammonium chloride and nanometer titanium dioxide, carrying out an oscillation reaction under microwave irradiation, performing centrifuging, washing and drying successively, adjusting a temperature, keeping the temperature, and conducting crushing to obtain pretreated sepiolite powder; carrying out vacuum melting on a thermoplastic polyurethane elastomer, adding the pretreated sepiolite powder, performing uniform mixing, conducting spinning, and performing blending with high silica glass fibers to obtain inner-layer fibers; blending the inner-layer fibers and functional medical stone fibers to coat the outer sides of the inner-layer fibers with the functional medical stone fibers, and carrying out cutting off to obtain outer-layer fibers; and adding water, performing uniform stirring, adding the pretreated cement base material, and performing uniform stirring to obtain the lightweight high-strengthhydraulic engineering concrete.
本发明公开了一种轻质高强度水利工程混凝土制备方法，包括如下步骤：制备预处理水泥基料；搅拌状态下向海泡石粉中加入水，加入十八烷基三甲基氯化铵、纳米二氧化钛，微波照射下震荡反应，离心，洗涤，干燥，调节温度，保温，粉碎得到预处理海泡石粉；将热塑性聚氨酯弹性体真空熔融，加入预处理海泡石粉混合均匀，纺丝后与高硅氧玻璃纤维混纺得到内层纤维；将内层纤维、麦饭石功能纤维混纺使麦饭石功能纤维包覆于内层纤维外侧，截断得到外层纤维；再加入水搅拌均匀，再加入预处理水泥基料搅拌均匀得到轻质高强度水利工程混凝土。
