Pavement brick prepared from construction waste recycled aggregate and preparation process thereof
The invention provides a pavement brick prepared from construction waste recycled aggregate and a preparation process of the pavement brick. The pavement brick is a recycled aggregate pavement brick with a surface layer. The surface layer mainly comprises the following raw materials in percentage by mass: 22-29% of cement, 62-70% of natural aggregate and 6-13% of water. And the bottom layer mainlycomprises the following raw materials in percentage by mass: 12-15% of cement, 46-52% of brick-concrete mixed recycled aggregate, 21-29% of concrete recycled aggregate, 3-6% of mineral admixture and8-10% of water. The pavement brick provided by the invention has better appearance quality, higher compressive strength, higher freezing resistance and lower water absorption, the construction waste is fully utilized while the pavement brick with excellent performance is prepared, and the full utilization of resources is ensured.
本发明提供一种建筑垃圾再生骨料制备的路面砖及其制备工艺，该路面砖为带面层的再生骨料路面砖；其中，面层主要包含以下质量百分比的原料：水泥22‑29％、天然骨料62‑70％、水6‑13％。底层主要包含以下质量百分比的原料：水泥12‑15％，砖混混合再生骨料46‑52％、混凝土再生骨料21‑29％、矿物掺合剂3‑6％、水8‑10％。本发明提供的路面砖具有较好的外观质量，较高的抗压强度，抗冻性及较小的吸水率，在制备性能优异的路面砖同时充分利用建筑垃圾，保证资源的充分利用。
