摘要
研究了不同掺量磷渣对混凝土外加剂适应性的影响。结果表明:磷渣具有减水效应,掺磷渣的水泥砂浆的泌水率有所增加,强度有所降低,收缩率差异不大,凝结时间延长。外加剂适应试验中磷渣在的减水率、凝结时间、泌水率、收缩率、强度等指标上对ZB-1D的适应性最好。
The study researches effect of phosphorous slag of different proportion on adaptability of additive in concrete.Results show that：In cement mortar of additive,phosphorous slag has reduce-water effect ,bleeding rate gets higher, strength gets lower, shrinkage is not too and settling time has prolonged.The additive of ZB-ID is better in the reduce-water rate, settling time,bleeding rate, shrinkage and strength in the test of adaptability of additive.
