Preparation method and processing device of recycled fine aggregate high-strength self-compacting concrete
The invention relates to the technical field of concrete, and particularly discloses a preparation method and processing device of recycled fine aggregate high-strength self-compacting concrete. The method comprises the following steps: S1, putting a recycled aggregate raw material into a raw aggregate feeding hopper (203), and adding Portland cement, slag and a thickening agent into a feeding box(302); S2, starting a servo motor (2041) and a high-speed motor (210), and feeding the recycled aggregate raw material in the raw aggregate feeding hopper (203) into a coarse aggregate crushing box (202) at a constant speed for crushing treatment; S3, simultaneously starting a second auger feeding machine (301) and a first auger feeding machine (4) to discharge all the raw material components into a mixing barrel (101) after a certain amount of fine aggregate is collected in a fine aggregate collecting box (201), simultaneously starting a water suction pump (116) to add a proper amount of water into the mixing barrel (101), and then starting a stirring motor (107); and S4, after the stirring motor (107) carries out stirring for 15-20 min, turning off the stirring motor (107), and pullingout a baffle plate (104), so that the recycled fine aggregate high-strength self-compacting concrete is obtained.
本发明涉及混凝土的技术领域，具体公开一种再生细骨料高强自密实混凝土的制备方法及加工设备；包括如下步骤：S1：将再生骨料原料放入原骨料加料斗(203)中，同时将硅酸盐水泥、矿渣和增稠剂加入加料箱(302)；S2：启动伺服电机(2041)和高速电机(210)，将原骨料加料斗(203)中的再生骨料原料匀速投入粗骨料破碎箱(202)中进行破碎处理；S3：待细骨料收集箱(201)中细骨料一定量后同时启动第二绞龙上料机(301)和第一绞龙上料机(4)将原料组分全部排入混料筒体(101)中，同时启动抽水泵(116)向混料筒体(101)加入适量水后在启动搅拌电机(107)；S4：待搅拌电机(107)搅拌15～20min后，关闭搅拌电机(107)，并抽出挡料板(104)即得一种再生细骨料高强自密实混凝土。
