Rubber recycled concrete and preparation method thereof
The invention relates to rubber recycled concrete and a preparation method thereof. The mass ratio of cement to natural coarse aggregate to recycled coarse aggregate to natural fine aggregate to recycled fine aggregate to water to rubber powder to nano silicon dioxide to a polycarboxylic acid water reducing agent is 1: (2.03-2.12): (0.87-0.91): (1.04-1.14): (0.47-0.49): (0.46-0.52): (0.011-0.057): (0.005-0.031): (0.011-0.026), the water-binder ratio of the rubber recycled concrete is 1: (2-2.17), the recycled fine aggregate and the recycled coarse aggregate are waste gas concrete, the natural fine aggregate is natural river sand, the natural coarse aggregate is limestone gravel, the particle size of the recycled fine aggregate is 0.075-4.75 mm, the particle size of the recycled coarse aggregate is 5-20 mm, the particle size of the natural fine aggregate is 0.075-4.75 mm, and the particle size of the natural coarse aggregate is 5-25 mm. According to the rubber recycled concrete disclosed by the invention, waste gas concrete and rubber can be utilized, the rubber recycled concrete has excellent mechanical properties, and the problem of poor compression resistance of recycled concrete in the prior art is solved.
本发明涉及一种橡胶再生混凝土及其制备方法，水泥、天然粗骨料、再生粗骨料、天然细骨料、再生细骨料、水、橡胶粉、纳米二氧化硅和聚羧酸减水剂的质量比为：1:(2.03～2.12):(0.87～0.91):(1.04～1.14):(0.47～0.49):(0.46～0.52):(0.011～0.057):(0.005～0.031):(0.011～0.026)，橡胶再生混凝土的水胶比为1:(2～2.17)，再生细骨料和再生粗骨料分别为废气混凝土，天然细骨料为天然河砂，天然粗骨料为石灰岩碎石，再生细骨料的粒径为0.075～4.75mm，再生粗骨料的粒径为5～20mm，天然细骨料的粒径为0.075～4.75mm，天然粗骨料的粒径为5～25mm。基于本发明的橡胶再生混凝土，不仅可以利用废气混凝土和橡胶，且具有优异力学性能，解决了现在技术中再生混凝土抗压性能差的问题。
