Treatment method of ceramsite for concrete, and pervious concrete taking ceramsite as coarse aggregate
The invention provides a treatment method of ceramsite for concrete, and a pervious concrete taking the ceramsite as coarse aggregate. The ceramsite obtained by adopting the treatment method can effectively reduce the water absorption of the ceramsite and improve the cylinder compressive strength of the ceramsite, and when the ceramsite is used as coarse aggregate for pervious concrete, the strength of the pervious concrete and the anti-stripping performance of the ceramsite in the pervious concrete can be remarkably improved. The treatment method comprises the following steps: 1) putting 1 m<3> of ceramsite into a treatment container, and vacuumizing under the vacuum degree of 0.2-0.5 MPa; 2) dissolving 108 rubber powder in water to prepare an aqueous latex solution, adding ordinary Portland cement, a first water reducing agent and a first water retention thickening agent to prepare 0.3-0.5 m<3> of a self-leveling cement paste, injecting the self-leveling cement paste into the treatment container, stirring for 180-240 s under the condition that the vacuum degree is kept at 0.2-0.5 MPa, separating out and naturally airing after ceramsite, and preserving moisture and maintaining for28 d for later use.
本发明提供一种混凝土用陶粒的处理方法及以所述陶粒作为粗骨料的透水混凝土，采用所述处理方法得到的陶粒可有效降低陶粒的吸水率、提高其筒压强度，所述陶粒作为粗骨料用于透水混凝土可显著改善所述透水混凝土的强度、以及其中陶粒的抗剥落性能。所述处理方法包括以下步骤：1)把1m陶粒放入处理容器内于真空度为0.2‑0.5MPa下抽真空；2)108胶粉溶于水制得乳胶水溶液；加入普通硅酸盐水泥、第一减水剂以及第一保水增稠剂，制备出自流平水泥浆体0.3‑0.5m，注入所述处理容器内，保持真空度为0.2‑0.5MPa的状态下搅拌180‑240s，分离出陶粒后自然晾干，保湿养护28d后备用。
