Method for producing environment-friendly paving brick by recycling ocean bottom sediment and paving brick
The invention relates to a method for producing an environment-friendly paving brick by recycling marine bottom sediment and the paving brick. A sample preparation process for producing the paving brick by utilizing the marine bottom sediment in the method comprises the following steps: mixing, putting into a mold, compacting and curing. In the mixing process, a binder, the ocean bottom sediment and the aggregate are firstly mixed by a dry method, a proper amount of water is rapidly added, and then the mixture is stirred to be uniformly mixed. The material mixture is poured into a mold in a layered mode, demolding is conducted immediately after compaction, and a demolded sample is subjected to air curing for 7 days and 28 days at the room temperature. The invention also provides the pavingbrick prepared by the method. The method solves the problem of disposal of the polluted marine dredged sediment, and successfully recycles the marine bottom sediment to produce the green and environment-friendly paving brick. The environment-friendly paving brick has the characteristics of high strength, low pollutant leaching rate, high durability and the like. The marine dredged sediment treatment cost is greatly reduced, the environmental burden is reduced, and remarkable economic benefits are achieved.
本发明涉及一种回收利用海洋底泥生产环保型铺路砖的方法及铺路砖，该方法利用海洋底泥生产铺路砖的样品制备过程包括混合、入模、压实、养护。混合的过程中，粘结剂，海洋底泥和骨料先进行干法混合，迅速加入适量的水，再搅拌使混合物均匀混合。把混好的材料分层倒入模具，压实后立即脱模，脱模后的样品在室温下进行7天和28天的空气养护。以及该方法制得的铺路砖。本发明解决了污染的海洋疏浚底泥的处置难题，成功地回收利用海洋底泥生产出绿色环保的铺路砖。该环保铺路砖具有高强度、低污染物浸出率，高耐久性等特点。大大降低海洋疏浚底泥处理成本，减少环境负担，具有显著的经济效益。
