摘　　要：石膏砌块具有耐水性差的缺点,从而限制其使用领域。基于这一问题,文章总结了目前耐水石膏砌块处理技术的研究进展,其中采用在建筑石膏中掺入有机防水剂与活性火山灰质等材料制备耐水石膏砌块的方法具有防水效果好、强度高的优点。但是成本较单独掺活性火山质材料高,并且还存在石膏掺量低、制备工艺复杂等不足,若能在建筑石膏中只掺入活性火山灰质等材料,同时提高石膏掺量制备耐水石膏砌块,该制备技术的应用前景将更为广阔。Owing to gypsum block＇s disadvantage of poor water-proofing, the paper summarized some methods which can improve gypsum block＇s disadvantage by looking up lots of literatures. The results showed that there were mainly three methods： one was adding the activated pozzolana to gypsum; the other was adding organic water repellents; thirdly, the two materials （the activated pozzolana and organic water repellents） were added to gypsum at some rate. The first method was the most economical, If the gypsum block could be water-proofing only by adding the activated pozzolana, the prospect would be broad.
