Lithium slag recycled concrete
The invention relates to the technical field of building materials, and particularly discloses lithium slag recycled concrete which comprises the following components in parts by mass: 100 parts of water; 140 to 145 parts of cement; 140 to 145 parts of modified lithium slag; 450 to 460 parts of fine aggregate; 625 to 635 parts of recycled coarse aggregate; 4.5 to 4.7 parts of a water reducing agent; the modification method of the modified lithium slag comprises the following steps: 1) grinding the lithium slag to 200-230 meshes to obtain lithium slag powder; the method comprises the following steps of 1, mixing lithium slag powder with a modification liquid, soaking the lithium slag powder in the modification liquid, and carrying out ultrasonic oscillation for 15-25min, and 2, filtering and drying to obtain the modified lithium slag, in the step 2, the modification liquid is a compound of secondary alkyl sodium sulfonate, coconut oil diethanolamide, nonyl ethylene glycol monomethyl ether and water.The method has the advantage that the influence on the concrete strength is reduced when a large amount of lithium slag is doped.
本发明涉及建筑材料技术领域，具体公开了一种锂渣再生混凝土,锂渣再生混凝土包括以下质量份数的组分：水100份；水泥140‑145份；改性锂渣140‑145份；细骨料450‑460份；再生粗骨料625‑635份；减水剂4.5‑4.7份；改性锂渣的改性方法如下：步骤1），将锂渣研磨至200‑230目，得锂渣粉；步骤2），将锂渣粉、改性液混合，使锂渣粉浸泡在改性液中，超声波震荡15‑25min；步骤3），过滤、干燥，得改性锂渣；步骤2）中，改性液为仲烷基磺酸钠、椰子油二乙醇酰胺、壬乙二醇单甲醚、水的复配。本发明具有大量掺用锂渣时降低对混凝土强度的影响的优点。
