掺磷渣粉混凝土的基本性能试验

现在工程中大量使用粉煤灰作为掺和料，用来提高混凝土的强度、改善混凝土的抗渗、抗侵蚀等性能，这样也使得粉煤灰供不应求，经济成本增加并且资源短缺。为了解决这种矛盾，开发新的资源作为补充已经势在必行。磷渣粉是生产黄磷时产生的工业废渣，资源十分丰富，且大量的磷矿渣均采用露天堆放造成了环境污染。为了改善环境，提高磷矿渣利用率，本文进行了一系列试验来研究磷渣粉作为掺和料的可行性。

Study on Some Basic Performances of Concrete with Phosphorus Slag Powder

In order to improve concrete strength and capability against permeability and corrosion, large amount of flying ash is used as mixture, which causes shortage of flying ash and increase the cost ,therefore to develope a new king of mixture is of necessity. Phosphorus slag is the by-product of phosphate fertilizer, and is very rich in our country; meanwhile, large amount of exposed phosphorus slag can produce environmental pollution. In order to improve environment and better utilize phosphorus slag, the paper has designed a series of experiment to study the possibility of using phosphorus as admixture.
