掺磷渣粉与粉煤灰的碾压混凝土性能比较研究

Comparative study on the performance of roller compacted concrete with phosphorus slag powder or fly ash

以磷渣粉和粉煤灰作为碾压混凝土掺合料,比较研究了单掺磷渣粉及粉煤灰、复掺磷渣粉和粉煤灰对碾压混凝土的力学性能、耐久性、变形性能及热学性能的影响。结果表明:掺磷渣粉与粉煤灰的碾压混凝土性能差别不大,两者复掺复合效应不明显。

Using phosphorus slag powder and fly ash as roller compacted concrete admixture, a test was carded out to study the impact of phosphorus slag powder and fly ash on the mechanical, durability, deformation and thermal properties of roller compacted concrete comparatively.The results show that the performance of roller compacted concrete with phosphorus slag powder as admixture was not very different from that with fly ash, while it was not obvious about their compound effect.
