Preparation method of precoated coarse aggregate/steel fiber reinforced concrete
The invention discloses a preparation method of precoated coarse aggregate/steel fiber concrete, which comprises the following steps: spraying a sizing material on coarse aggregate/steel fiber, and mixing with other raw materials of the concrete after the sizing material forms an adhesive film layer which is not completely cured and has certain deformability and cohesive force on the surface of the coarse aggregate/steel fiber; before mixing, a sizing material is sprayed on the coarse aggregate/steel fiber, and the coarse aggregate/steel fiber is mixed with other materials of the concrete when a sizing material layer is cured until the surface is dry, has certain adhesive force and plasticity and has subsequent bonding capacity, so that the purpose of enhancing an interface between the aggregate and a hydrate in the concrete is achieved; therefore, the mechanical property and durability of the concrete are improved.
本发明公开了一种预涂层粗骨料/钢纤维混凝土的制备方法，包括以下步骤：在粗骨料/钢纤维上喷洒胶料，待胶料在粗骨料/钢纤维表面形成未完全固化且具有一定变形能力和粘结力的胶膜层后再与混凝土其他原材料拌合；拌合前通过在粗骨料/钢纤维喷洒胶料，待胶料层固化至表干具有一定附着力和可塑性且具有后续可粘结能力的状态下与混凝土其他材料拌合，以达到增强混凝土中骨料和水化物之间的界面的目的，从而提高混凝土力学性和耐久性的目的。
