磷渣混凝土的抗硫酸盐侵蚀性能研究

Study on sulfate resistance of phosphorus slag concrete

随着混凝土普遍应用,混凝土的耐久性得到越来越多的重视,而硫酸盐侵蚀是影响混凝土耐久性的一个重要因素,是实际工程中面临的重大难题。为了研究磷渣掺合料对混凝土抗硫酸盐侵蚀性能的影响,通过试验分析,对磷渣、粉煤灰和矿渣的抗硫酸盐侵蚀性能相对比,得出磷渣在抗硫酸盐侵蚀方面的优越性,以及研究了磷渣的掺量对混凝土抗硫酸盐侵蚀性能的影响,确定混凝土中磷渣的最佳掺量,为混凝土耐久性研究提供参考。

With the universal application of concrete, the durability of concrete has been paid more and more attention, while the sulfate erosion is an important factor affecting the durability of concrete, and is a major problem faced in the actual project.To study the sulfate resistance of phos- phorus slag concrete, through experimental analysed, the sulfate resistance of the slag, fly ash and slag was paralleled to obtain the superiority of phosphorus slag in the sulfate resistance, and studied the effect of phosphorous slag content to the erosion properties of concrete resistance to sul- fate, to determine the best dosage of phosphorus slag in the concrete,provided a reference for the durability of concrete research.
