Recycled brick aggregate concrete and preparation method thereof
The invention belongs to the technical field of building materials, and particularly relates to recycled brick aggregate concrete and a preparation method thereof. According to the regenerated brick aggregate concrete provided by the invention, the polypropylene fibers are used as reinforcing fibers to prepare the regenerated brick aggregate concrete, so that the bonding strength of a matrix can be improved, the mechanical property of the regenerated brick aggregate concrete is further improved, and the compressive strength and the splitting tensile strength are improved. According to the invention, the silicon powder is doped, so that the impermeability of the concrete can be improved, the high-molecular polymer styrene-butadiene latex is added to prevent further expansion of cracks, the integrity of the structure is ensured, the flexibility of the concrete material is improved, and meanwhile, the defect that the concrete is shrunk and cracked due to the addition of the silicon powder is also avoided. The mechanical property of the recycled brick aggregate concrete is guaranteed, meanwhile, good anti-permeability performance and flexibility of the concrete are guaranteed, and application and popularization of the recycled brick aggregate concrete can be promoted.
本发明属于建筑材料技术领域，具体涉及一种再生砖骨料混凝土及其制备方法。本发明提供了一种再生砖骨料混凝土，将聚丙烯纤维作为增强纤维制备再生砖骨料混凝土，能够提高基体的粘结强度，进而提升再生砖骨料混凝土的力学性能，使抗压强度和劈裂抗拉强度得到提高。本发明掺加硅粉，能够提高混凝土的抗渗能力，加入高分子聚合物丁苯胶乳阻止裂缝进一步扩展，保证结构的完整性，提升了混凝土材料的柔韧性，同时也避免了因硅粉的加入带来的混凝土干缩开裂的缺陷。本发明在保证再生砖骨料混凝土力学性能的同时，保证了混凝土良好的抗渗性能及柔韧性，能够推动再生砖骨料混凝土的应用和推广。
