抗硫酸盐水泥

研究结果表明：黄铁矿及其所产生的SO2－4对普通硅酸盐水泥浆材在180d内的作用较弱，建议在含有黄铁矿区域的帷幕水泥浆材采用高抗硫酸盐水泥浆材；

The test results show that the pyrite and here from produced SO 2 - 4 present a weak effect on properties of a Portland cement grouting material . It is suggested that a highly sulphate resistant cement must be used in curtain grouting in regions where pyrite exist .

生产低碱高抗硫酸盐水泥的一些要点

Several Key Points in the Production of High Sulfate Resistant Cement with Low Alkali Content

在干湿交替的水侵蚀环境中，不宜采用普通水泥混凝土和抗硫酸盐水泥混凝土；

In the alternation of wetting-dry water corrosion environment , the Portland cement concrete and the anti-sulfate cement concrete are not suitably used ;

缓凝砂浆的凝结时间与水泥品种也有较大关系，同配比下早强型水泥凝结时间短，抗硫酸盐水泥凝结时间长。

And in addition , the setting time of retarding mortar had something to do with the cement type , if given the same proportion , the setting time of early strength cement is short and that of sulphate cement is long .
