工业废弃物与生活垃圾多种组分混凝土强度试验

Industrial Wastes and Living Garbage Multiple Combinations of Concrete Strength Test

单一大量废弃物的添加对混凝土的强度有较大的损害,为使混凝土在利用废弃物时,保持其强度,减轻废弃物对水泥性能的影响,调整了掺加粉煤灰,炉渣,垃圾焚烧灰,建筑垃圾,电镀污泥,城市污水河底泥的比例,并就这种复合废弃物制成水泥试样进行力学性能测量,得出结论,除个别废弃物不宜使用外,适当选择废弃物种类与比例,在水泥中掺加这种复合废弃物,对水泥的力学性能所受影响也不是太大,即水泥利用复合废弃物具有一定的可行性与必要性,利用了废物,降低了成本,保护了环境,经济意义与社会意义比较突出.

A large number of waste to add have greater damage to the strength of concrete. In order to use waste in the concrete, maintaining its strength, reducing waste and influence on the properties of cement, the experiment has adjusted the proportion of fly ash, slag adjustment, waste incineration ash, construction waste, electroplating sludge, city sewage river sed- iment percentage. After the test of the composite cement sample measurement of mechanical properties, the conclusion is , the individual waste should not be used, and the appropriate selection of waste type and proportion, mixing with the composite , on the cement mechanical properties affected is not too large. Using composite waste in cement has certain feasibility and necessity, using the waste, reducing costs, protecting the environment. The economic significance and social significance is very prominent.
