硫铝酸盐“S”型瞬凝水泥

“S”SULPHATE-ALUMINATE INSTANTANEOUS HARDENING CEMENT

研究了一种在９５０℃左右缎炼温度下烧成的硫铝酸盐“Ｓ”型瞬凝水泥方法，该水泥具有速凝、早期强度高、微膨胀等优点；此外，这种硫铝酸盐“Ｓ”型瞬凝水泥在应用中，具有堵漏成功率高、用量少、成本低和候凝时间短等优点。

This paper explains a methdused to produce cement when the calcination temperatureis about 950℃. Cement sintered this way is characterized by great strength at its earlystage,instantaneous hardening and slight expansion。The paper also describes the uses of“S”sulphatealuminate quick-hardening cement,in which there has been obtainrnent of suchgood effects as high rate of success in leak-blocking,less quantity,low cost and shorterwaiting time。
