Abstract

本发明涉及一种制造水泥用的粉煤灰活化剂及其制作方法,将偏硅酸钠、氟硅酸钠、三聚磷酸钠按一定比例混合,加热后干燥脱水后粉碎。本发明具有活化效果好的优点,生产的水泥在抗压和抗折强度方面尤为突出,大大超过国家标准。

Description

粉煤灰活化剂
本发明涉及一种制造水泥用的粉煤灰活化剂及其制作方法。
现有的粉煤灰活化剂,如上海化工研究院研制的活化剂、安徽大学研制的HB活化剂、南昌大学研制LZ活化剂,活化效果不够理想,致使生产的水泥在抗压和抗折强度方面不够理想。
本发明的目的就是要提供一种活化效果好,使生产的水泥在抗压和抗折强度方面达到较好水平的煤灰活化剂。
实现本发明目的的技术方案为,该粉煤灰活化剂是通过以下步骤制成的:
1、混合:按重量百分比将氧化钙30%~50%、偏硅酸钠20%~30%、氟硅酸钠20%~30%、三聚磷酸钠6%~10%;
2、加热:温度50℃~80℃,时间2~4小时
3、干燥:使水分小于3.0%;
4、粉碎:细度在150目以上。
本发明具有活化效果好的优点,生产的水泥在抗压和抗折强度方面尤为突出,大大超过国家标准。
下面结合实施例对本发明进行详述,下表为几组ISO法实验数据,其中粉煤灰使用量为35%,活化剂使用量为1.7%,氧化钙、偏硅酸钠、氟硅酸钠、三聚磷酸钠四种成分使用量是指其使用量占活化剂的重量百分比;
