中文摘要	本文以青海湖周边沙漠化沙粒为研究对象,全面分析了其理化性能,研究了沙粒掺入对石膏力学性能的影响。试验表明: 青海湖周边沙漠化沙粒主要矿物相为石英和钠长石; 沙粒形状大小各异,表层有一定量的物理吸附物; 沙粒在碱和水中的溶解量很小,在酸中的溶解量在3. 5% ~ 6. 1% 之间。沙粒使石膏胶凝材料强度先增加后降低,当沙粒的掺量为10%时,强度最大,其抗压强度为15 MPa,抗折强度为6. 4 MPa; 掺量为50%时,强度最小,其抗压强度为10. 9 MPa,抗折强度为4. 7 MPa。
英文摘要	Qinghai lake is the largest inland lake in China,as well as a major tourist site of qinghai province. The surrounding sand has posed a direct threat to the water area of qinghai lake in recent years. The sand around Qinghai lake was chosen as the research object in this paper. The physicochemical properties were analysed and, the sand mixed with mechanical properties of gypsum were studied. The tests showed that sand desertification around the Qinghai Lake is the main mineral phases quartz and albite,Sand has different shapes and sizes,its surface has a certain amount of physical adsorption substance,The dissolution of sand in alkali liquor and water is very small,sand dissolved range is 3. 5% to 6. 1% in acid liquor,Strength of gypsum binding materials with sand is first increased and then decreased,The strength of gypsum binding material is maximum when the sand content is 10%, its compressive strength is 15 MPa,breaking strength is 6. 4 MPa. The strength of gypsum binding material is smallest when the sand content is 50%,its compressive strength is 10. 9 MPa,breaking strength is 4. 7 MPa. This study will provides basic date for high performance 、suitable plant growth、lowcost gypsum sand-fixation plant raw material and the desert Water-save equipment design in Qinghai-tibet plateau environment.
