Preparation process of high-toughness self-compacting bridge deck pavement concrete
The invention provides a preparation process of high-toughness self-compacting bridge deck pavement concrete, and relates to the field of concrete preparation. The preparation process of the high-toughness self-compacting bridge deck pavement concrete comprises the following steps: S1, proportioning the cement, the sand, the stones, the water and the additive, S2, adding the raw materials into a concrete mixer, and fully stirring until the concrete reaches the specified flowability and uniformity, and S3, pouring the stirred concrete into a position, needing to be paved, of a bridge deck, so as to obtain the high-toughness self-compacting bridge deck pavement concrete. And S4, a self-compacting agent is used for treating the surface of the concrete, a micro-pore structure is generated, and the surface of the concrete is made to have self-compacting performance and high toughness. The problem that the strength is reduced due to the diameter of the aggregate is avoided by detecting the quality of the concrete aggregate, the quality of the concrete is ensured by controlling the diameter of the silica fume, and the self-compacting stability is improved through good curing under the control of the self-compacting agent and the corresponding temperature and humidity.
本发明提供高韧性自密实桥面铺装混凝土制备工艺，涉及混凝土制备领域。该基于高韧性自密实桥面铺装混凝土制备工艺，包括，S1、将水泥、沙子、石子、水和添加剂进行配比，S2、将原材料加入混凝土搅拌机中，进行充分搅拌，直到混凝土达到规定的流动性和均匀性，S3、将搅拌好的混凝土倒入桥面需要铺装的位置，用振动器将混凝土均匀压实，S4、使用自密实化剂处理混凝土表面，生成微细孔隙结构，使混凝土表面具有自密实性和高韧性。通过对混凝土骨料进行质量检测，避免骨料直径造成强度下降的问题，并通过微硅粉直径的控制保证混凝土的质量，通过自密实化剂，以及在对应的温度与湿度控制下，通过良好的养护增加自密实稳定性。
