Recycled coarse aggregate seawater sea sand concrete as well as preparation method and application thereof
The invention provides recycled coarse aggregate seawater and sea sand concrete as well as a preparation method and an application thereof, and the recycled coarse aggregate seawater and sea sand concrete is prepared from cement, natural coarse aggregate, sea sand, recycled coarse aggregate, seawater, fly ash, silica fume, additional water and a water reducing agent, by using a certain proportionof fly ash and taking the fly ash as mineral admixtures to replace part of the cement, the durability, compression strength and breaking strength of the recycled coarse aggregate concrete can be improved, the recycled coarse aggregate is adopted to replace part of natural coarse aggregate, building waste can be fully recycled, the preparation method is simple and easy to operate, the durability and mechanical properties of the prepared recycled coarse aggregate seawater sea sand concrete are improved, and the application prospect is wide. The product can be well applied to constructional engineering.
本发明提供了一种再生粗骨料海水海砂混凝土及其制备方法和应用，包括一定配比的水泥、天然粗骨料、海砂、再生粗骨料、海水、粉煤灰、硅灰、附加水、减水剂制成，通过在采用一定配比的粉煤灰和粉煤灰作为矿物掺合料，替代部分水泥，可以提高再生粗骨料混凝土的耐久性和抗压、抗折强度，采用再生粗骨料代替部分天然粗骨料，可充分回收利用建筑废料，并且，本发明的制备方法简单易操作，所制备的再生粗骨料海水海砂混凝土耐久性和力学性能都得到了提高，可很好地应用于建筑工程中。
