Polyester fiber reinforced recycled concrete product and preparation method thereof
The invention relates to a polyester fiber reinforced recycled concrete product and a preparation method thereof. The polyester fiber reinforced recycled concrete product comprises the following raw materials: 487.5 kg/m<3> of cement, 631 kg/m<3> of sand, 804.3 kg/m<3> of natural aggregate, 344.7 kg/m<3> of recycled aggregate, 9.75 kg/m<3> of a water reducing agent, 198.5 kg/m<3> of water and 0.6-0.9 kg/m<3> of polyester fibers. The preparation method comprises the following steps: (1) crushing recycled aggregate, namely crushing the recycled aggregate and screening the aggregate; (2) preparing a polyester fiber reinforced recycled concrete product, namely mixing and molding the recycled aggregate, cement, sand, stones, water, a water reducing agent and polyester fibers to obtain the recycled concrete product; and (3) curing the recycled concrete. According to the concrete product, the water absorption rate is reduced, the tensile strength and the compressive strength are improved, thecrack resistance is obviously improved, and waste building materials are reasonably utilized.
本发明涉及一种聚酯纤维增强再生混凝土制品及其制备方法，其原料包括水泥487.5kg/m3，砂子631kg/m3，天然骨料804.3kg/m3，再生骨料344.7kg/m3，减水剂9.75kg/m3，水198.5kg/m3，聚酯纤维0.6‑0.9kg/m3；按照以下方法制成：(1)再生骨料的破碎：对再生骨料进行破碎并对骨料进行筛分；(2)聚酯纤维增强再生混凝土制品制备：将再生骨料、水泥、砂子、石子、水、减水剂与聚酯纤维一起拌合成型，得到再生混凝土制品；(3)对再生混凝土进行养护。本发明的混凝土制品吸水率降低，抗拉和抗压强度得到提高，抗裂性能得到明显改善，且使废旧建筑材料得到合理利用。
