Preparation method of pre-wrapped toughened coral aggregate and seawater and sea sand coral aggregate concrete
The invention discloses a preparation method of pre-wrapped toughened coral aggregate and seawater sea sand coral aggregate concrete, and belongs to the technical field of building material application and concrete. Comprising the following steps: pre-wetting a proper amount of coral aggregate; dividing the pretreated aggregate into two parts, and performing reinforcement treatment on the two parts of the aggregate by using a reinforcement material A and a reinforcement aggregate B respectively; the reinforced coral aggregate, seawater, sea sand and cement are used as raw materials to prepare the seawater sea sand coral aggregate concrete. According to the invention, a hole-plugging shell-making strengthening method is adopted to fill the pores of the coral aggregate and form a compact wrapping layer outside the aggregate, so that the effects of reducing the overall porosity of the coral aggregate concrete and optimizing an interface transition area between the aggregate and a cementing material are achieved, in addition, the transverse deformation of the concrete is effectively improved, and the ductility of the concrete is increased; the concrete compressive strength, the axial compressive strength and the splitting tensile strength are improved, and the engineering applicability of the coral aggregate concrete in ocean island reef and coast construction is improved.
本发明公开了一种预裹增韧珊瑚骨料及海水海砂珊瑚骨料混凝土的制备方法，属于建筑材料应用与混凝土技术领域。包括下列步骤：取适量珊瑚骨料预湿；将预处理的骨料分为两部分，分别使用强化材料A以及强化骨料B对两部分骨料进行强化处理；以强化珊瑚骨料与海水、海砂、水泥为原料制备海水海砂珊瑚骨料混凝土。本发明采用堵孔造壳的强化方法，填充珊瑚骨料孔隙，并在骨料外部形成致密包裹层，达到减少珊瑚骨料混凝土整体孔隙率，优化骨料与胶凝材料之间界面过渡区的效果，此外还有效改善混凝土的横向变形，增加混凝土的延性，提高混凝土抗压强度、轴心抗压强度及劈裂抗拉强度，提升珊瑚骨料混凝土在海洋岛礁及海岸建设的工程适用性。
