Artificial lightweight aggregate with multistage gradient structure and preparation method thereof
The invention discloses an artificial lightweight aggregate with a multistage gradient structure, and belongs to the technical field of artificial lightweight aggregates. The artificial lightweight aggregate comprises a core, a lightweight transition layer, a sub-lightweight transition layer and a shell which are distributed from inside to outside, the raw materials of the core comprise a multi-source solid waste material and a rapid foaming agent; the raw materials of the light transition layer comprise a multi-source solid waste material, a rapid foaming agent and a slow-release pore-forming agent; the raw materials of the sub-lightweight transition layer comprise a multi-source solid waste material and a slow-release pore-forming agent; the raw materials of the shell comprise a multi-source solid waste material and an additive. The artificial lightweight aggregate disclosed by the invention is relatively low in bulk density and 1h water absorption rate, relatively high in cylinder compressive strength and specific strength and very good in application value.
本发明公开了一种具有多级梯度结构的人造轻骨料，属于人造轻骨料技术领域。本发明的人造轻骨料包括由内至外分布的核芯、轻质过渡层、亚轻质过渡层和壳体；核芯的原料包括多源固废材料和快速发泡剂；轻质过渡层的原料包括多源固废材料、快速发泡剂和缓释造孔剂；亚轻质过渡层的原料包括多源固废材料和缓释造孔剂；壳体的原料包括多源固废材料和外加剂。本发明的人造轻骨料，其堆积密度和1h吸水率较低，筒压强度和比强度较高，具有很好的应用价值。
