粉煤灰掺量对混凝土强度的影响

Powdery-ash to the Introduction of Concrete Intensity of the Impact

粉煤灰掺入混凝土中取代部分水泥不仅可以降低混凝土成本,还可以减轻煤废料污染,缓解矿物能源危机。本文尝试采用粉煤灰取代部分混凝土中胶凝材料—水泥,比较了在不同水胶比下不同的粉煤灰掺量对混凝土强度、和易性的影响。试验表明在混凝土中掺入适当的粉煤灰取代水泥不仅强度可以满足工程需要而且可以改善其和易性,降低成本。

Powdery-ash to replace Portland cement in some concrete cement not only reduces the cost of coal waste can also reduce pollution and mitigate the fossil energy crisis. The attempt to replace part Fenmeihui Jiaoning materials-concrete, cement, plastic more than water under the various different powdery ash Chanliang of concrete strength, vulnerable nature. Tests showed ; In concrete appropriate powdery ash to replace Portland cement works to meet the needs not only strength but also to improve their living nature, and reduce their costs.
