The invention provides a green concrete regeneration process, and relates to the technical field of building material processing, and the green concrete regeneration process comprises the following steps: S1, pretreating concrete blocks; s2, the concrete blocks are subjected to crushing treatment; s3, the pretreated concrete slag is subjected to magnetic separation treatment; s4, carrying out secondary crushing on the concrete slag subjected to magnetic separation; s5, the concrete slag obtained after secondary crushing is subjected to agent treatment; s6, dehydrating the concrete slag subjected to chemical treatment; s7, the dehydrated concrete residues are crushed again; s8, adjusting the pH value of the concrete slag; s9, dehydrating the concrete slag subjected to pH value adjustment again; and S10, putting into use. The mode that the concrete powder is subjected to kiln firing by keeping alkalinity is that the concrete powder has certain alkalinity, the property of the concrete powder is similar to that of cement powder, and the amount of reducing the structural strength of a re-formed concrete piece is reduced when the concrete powder is mixed with the cement powder for use.
本发明提供一种绿色混凝土再生工艺，涉及建筑材料加工技术领域，包括以下步骤：S1、对混凝土块进行预处理；S2、对混凝土块进行破碎处理；S3、对预处理后的混凝土渣进行磁选处理；S4、对磁选后的混凝土渣进行二次破碎；S5、对二次破碎后的混凝土渣进行药剂处理；S6、对药剂处理后的混凝土渣进行脱水处理；S7、对脱水后的混凝土渣再次进行破碎；S8、对混凝土渣进行酸碱度调节处理；S9、对酸碱度调节后的混凝土渣进行再次脱水处理；S10、投入使用。本发明保持碱性对混凝土粉末进行炉窑烧制的方式则是使得混凝土粉末本身具备一定的碱性，性质相近于水泥粉末，使其与水泥粉末混合使用时减少其降低重新结成的混凝土件的结构强度的量。
