本文介绍了用沙漠砂代替工程砂配制砂浆和混凝土的试验研究结果及其在实际工程中的应用情况。沙漠砂粒径极细、级配差、且具有一定的腐蚀性。本文分别在实验室和现场用沙漠砂配制砂浆和混凝土，掺以一定比例的外加剂，并在不同环境下养护，其抗压强度满足一般工程的要求。该材料已在塔克拉玛干沙漠腹地塔中４油田部分工程中应用，取得了良好的经济效益。 This paper introduces the experimental research results of sand mortar and concrete prepared by using desert sand instead of engineering sand and its application in practical engineering. Desert sand is very fine grained, poorly graded, and somewhat corrosive. In this paper, mortar and concrete are prepared in desert sand in laboratory and on site, mixed with a certain proportion of additives, and cured in different environments. Their compressive strength meets the requirements of general engineering. The material has been applied in part of the Tazhong 4 oil field in the hinterland of the Taklamakan Desert, and has achieved good economic benefits.
