【摘要】 混凝土膨胀剂在现代工程中的应用越来越广泛。本文通过试验检验利用工业废渣粉煤灰和磷石膏基于水化物脱水相技术制备的混凝土膨胀剂DE_0-500的性能,表明制备的混凝土膨胀剂能够达到膨胀剂标准所要求的限制膨胀率和强度指标,可用来配制补偿收缩混凝土。更多还原

【Abstract】 The applying area of expansive agents for concrete is becoming wider and wider in modern civil engineering.The major performances of expansive agent for concrete DE_0-500 prepared with industrial waste - fly ash and phosphogypsum by the technology of dehydrated hydrates phases were tested in this paper.The experiments indicate the expansive agent can achieve the limited expansion ratio and intensity requested by the expansive agent criteria,and may be used to make compensate shrinkage concrete.更多还原
