掺烧高钙粉煤灰用于水泥和混凝土的研究
normal style="LAYOUT-GRID-MODE: char; LINE-HEIGHT: 150%; mso-layout-grid-align: none">一、前言
normal style="LAYOUT-GRID-MODE: char; TEXT-INDENT: 27.8pt; LINE-HEIGHT: 150%; mso-layout-grid-align: none">众所周知，粉煤灰可广泛应用于建筑、建材领域，节约大量不可再生资源。但近年来开始在环保要求较高的沿海地区火电厂推广使用的低硫份、低灰份、高发热量的神木煤后所形成的高钙粉煤灰成色较差，f-CaO含量较高，易由于安定性问题给其在水泥和混凝土中应用带来不利影响。
normal style="LAYOUT-GRID-MODE: char; LINE-HEIGHT: 150%; mso-layout-grid-align: none"> 本文主要研究上海地区锅炉燃煤混烧所排放的高钙粉煤灰在水泥、混凝土中的应用效果。用于水泥胶砂和混凝土中进行性能试验的试样均来自W、M、P三个电厂电除尘压力罐处，其中电除尘一电场收集的灰样模拟粗灰库灰样，电除尘二、三电场收集的灰样模拟细灰库灰样，分别考察其在水泥、混凝土中的应用效果。

normal style="LAYOUT-GRID-MODE: char; TEXT-INDENT: 25.2pt; LINE-HEIGHT: 150%; mso-layout-grid-align: none">根据表5，可得到：
normal style="LAYOUT-GRID-MODE: char; TEXT-INDENT: 25.2pt; LINE-HEIGHT: 150%; mso-layout-grid-align: none">①P电厂#2细灰库粉煤灰可用于C20 ~ C50普通混凝土配制，该粉煤灰具有一定的减水效果和同水泥相当的胶凝效力，可以1：1取代15% ~ 30%的水泥。
normal style="LAYOUT-GRID-MODE: char; TEXT-INDENT: 25.2pt; LINE-HEIGHT: 150%; mso-layout-grid-align: none">② 表5中各系列配比通过28天强度验证，均达到设计要求。
normal style="LAYOUT-GRID-MODE: char; TEXT-INDENT: 25.2pt; LINE-HEIGHT: 150%; mso-layout-grid-align: none">③ 随混凝土设计强度等级变大，胶凝材料用量增多，可相应提高该粉煤灰在混凝土中的掺量。
normal style="LAYOUT-GRID-MODE: char; LINE-HEIGHT: 150%; mso-layout-grid-align: none"> 五、结论
normal style="LAYOUT-GRID-MODE: char; LINE-HEIGHT: 150%; mso-layout-grid-align: none"> 1、根据W、M和P电厂的抽样分析可知，粗灰库中灰样性能基本波动于DBGJ08-230-98规定的Ⅱ级高钙性能指标附近，尤其是其f-CaO和安定性指标合格，细灰库中灰样性能指标可以达到DBJ08-230-98规定的Ⅰ级高钙灰性能指标。
normal style="LAYOUT-GRID-MODE: char; LINE-HEIGHT: 150%; mso-layout-grid-align: none"> 2、水泥——粉煤灰净浆试验结果表明，在合理掺量条件下，混烧灰样不会引起安定性不良的现象产生。
normal style="LAYOUT-GRID-MODE: char; LINE-HEIGHT: 150%; mso-layout-grid-align: none"> 3、细灰库中粉煤灰减水效果明显，且具一定的胶凝效力，可以1：1的比例替代混凝土中水泥15%-30%。
normal style="LAYOUT-GRID-MODE: char; LINE-HEIGHT: 150%; mso-layout-grid-align: none"> 4、经合理级配，粗灰库中灰样也可以用于混凝土的配制。但在工程实际应用中，对游离氧化钙和安定性超标的粉煤灰，仍需非常谨慎，并严格控制。或通过后加工，经系统试验鉴定，体积安定性合格，并对混凝土强度、和易性及耐久性确实无不利影响，可考虑出厂使用。
