Damping-adjustable recycled aggregate concrete and preparation method thereof
The invention provides damping-adjustable recycled aggregate concrete which comprises the following components in parts by mass: 4-7 parts of recycled coarse aggregate; 0.5 to 3.5 parts of a micro damper; 0-2 parts of natural fine aggregate; 1.5 to 3.0 parts of cement; 0-1.5 parts of a mineral admixture; 0.005 to 0.025 part of a water reducing agent; and 1 part of water. The invention further provides a preparation method and application of the damping-adjustable recycled aggregate concrete. According to the damping-adjustable recycled aggregate concrete, the damping performance of the concrete can be effectively improved by 80-200%, the energy-dissipating capacity of the concrete is obviously improved, the cubic compressive strength can reach C30-C50, and the concrete has the same strength and similar elastic modulus as common concrete and can be used for vibration reduction of track traffic ballast beds and road beds, vibration isolation of building foundations and equipment foundations, vibration reduction of upper building structures and other projects.
本发明提供一种阻尼可调控再生骨料混凝土，按质量份计，包括以下组分：再生粗骨料4‑7份；微型阻尼器0.5‑3.5份；天然细骨料0‑2份；水泥1.5‑3.0份；矿物掺合料0‑1.5份；减水剂0.005‑0.025份；水1份。本发明进一步提供一种阻尼可调控再生骨料混凝土的制备方法及其应用。本发明提供的一种阻尼可调控再生骨料混凝土能够有效提高混凝土的阻尼性能80‑200％，明显改善混凝土的耗能能力，且立方体抗压强度可达到C30‑C50，具有与普通混凝土相同的强度和相近的弹性模量，可用于轨道交通道床和道路路基的减振、建筑基础和设备基础的隔振、上部建筑结构的减振等工程。
