The invention provides a preparation process of a light high-strength UHPC sphere material, and relates to the field of preparation processes of light high-strength UHPC sphere materials. The preparation process of the light-weight high-strength UHPC sphere material comprises the following steps: S1, preparing materials: mixing 736g of cement, 212g of silica fume, 160g of steel fiber, 28g of an additive, 1050g of quartz sand, 174g of water and 130g of fine filler, weighing by adopting an electronic balance, and weighing the required materials in advance in two times, S2, stirring by adopting a cement mortar stirrer for the light-weight high-strength UHPC sphere, and stirring by adopting a stirrer for stirring, thereby obtaining the light-weight high-strength UHPC sphere. The method comprises the following steps: firstly, carrying out medium-speed dry mixing on cement and other powder for 2 minutes; uHPC with higher strength is adopted for preparation, so that high bounce is guaranteed, a hollow structure is selected according to a sphere structure, on the premise that the weight limitation of the sphere is guaranteed, if a hollow structure system is adopted, the thickness of the shell must be controlled within 2.5 cm, and the existing technical basis of the technical center is combined according to the forming process.
本发明提供一种轻质高强UHPC球体材料制备工艺，涉及轻质高强UHPC球体材料制备工艺领域。该一种轻质高强UHPC球体材料制备工艺，包括以下步骤，S1：配料，所述轻质高强UHPC球体选用水泥736g、硅灰212g、钢纤维160g、外加剂28g、石英砂1050g、水174g、细填料130g进行混合而成，采用电子天平进行称量，分两次提前称取好所需材料，S2：搅拌，所述轻质高强UHPC球体采用水泥胶砂搅拌机，使用变速强制搅拌：首先中速干拌水泥和其他粉料2min。本发明采用更高强度的UHPC来制备，从而保证较高弹起，针对球体构造，选择了空心构造，在保证球体重量限制的前提下，若采用空心构造体系，则壳体厚度必须控制在2.5cm以内，针对成型工艺，结合技术中心现有的技术基础。
