Preparation process for preparing artificial stone from waste concrete
The invention belongs to the technical field of waste recycling, and particularly relates to a preparation process for preparing artificial stone from waste concrete. The preparation process comprises the following steps: Step 1, firstly, preparing ingredients to be used; Step 2, uniformly mixing and stirring the prepared ingredients to form flow-state concrete; Step 3, curing and forming the prepared flow-state concrete: feeding the uniformly stirred flow-state concrete into a plate mold, and placing the plate mold in a drying chamber for 48 hours to form cured concrete; Step 4, performing supercritical treatment on the cured concrete; and Step 5, cutting and grinding an artificial stone sample: cutting the artificial stone sample subjected to supercritical treatment into a plurality of groups of blocks, and grinding the artificial stone sample blocks into proper shapes and sizes through grinding equipment. By performing supercritical carbon dioxide treatment on the cured concrete mixture, the swelling and plasticizing effects of a latex microstructure inside the cured concrete are changed, the overall strength of the artificial stone is further improved, and the waste concrete is recycled.
本发明属于废物回收利用技术领域，具体的说一种废弃混凝土制备人造石的制备工艺，该制备工艺包括以下步骤：S1：首先准备需要使用的配料；S2：将准备好的配料混合搅拌均匀，形成流态混凝土；S3：将制得的流态混凝土固化成型：搅拌均匀的流态混凝土被送入板模中，并放置于干燥室内48h,形成固化混凝土；S4：对固化混凝土进行超临界处理；S5：对人造石样品切割打磨：将超临界处理后的人造石样品切割为若干组块，且通过打磨设备将人造石样品组块打磨为合适的形状以及尺寸；通过对固化混凝土混合物进行超临界二氧化碳处理，改变了固化混凝土内部乳胶微结构的溶胀和增塑作用，进一步提升了人造石整体的强度，使得废弃混凝土得到回收使用。
