| 中文摘要: |
| 改性脱硫石膏在工程领域有着广阔的应用前景，为研究养护条件对其抗压强度的影响，以养护条件为变量，通过对比试验，得到不同养护条件下改性脱硫石膏及其复合材料的强度值的变化，并加以分析。结果表明：对改性脱硫石膏及其复合材料先进行3d标准养护再转常温养护至28d的组合养护条件，更有利于改性脱硫石膏及其复合材料强度的发展；不仅早期强度增加明显，后期强度增值也较大。 |

| Modified desulfurization gypsum has wide application prospects in engineering field. In order to study the effect of curing conditions on comprehensive strength, a comparative experiment is conducted in which the strength of modified desulfurization gypsum and its composite mortar in different curing conditions is analysed. Results showed that the optimal curing condition was first 3d standard curing and then 28d room temperature curing. In that condition, the strength of modified desulfurization gypsum and its composite mortar developed better, with obvious strength increase in early period and also greater strength in later time. |
