| 摘 要： | 研究了脱硫石膏掺量对混凝土性能的影响。结果表明:脱硫石膏掺量在30%以内时,混凝土工作性和强度均符合C30混凝土标准。脱硫石膏掺量在15%以内时,能改善混凝土流动性;而当掺量增加到20%后,混凝土需水量增加,流动性下降。随着脱硫石膏掺量增加,混凝土早期强度发展较快,后期强度增长缓慢,混凝土各龄期强度相对减小。脱硫石膏掺量在30%以内的混凝土可以用于一般建筑工程和道路工程。

| Abstract: | The influence of dosage of the desulphurized gypsum on concrete function is studied.Test results indicated that when the dosage of desulphurized gypsum is within 30%,the workability and strength of the concrete are up to standard of the C30.When the dosage of the desulphurized gypsum is within 15%,the liquidity of concrete can be improved.However,when the dosage of desulphurized gypsum is increased to 20% and above,the water requirement of concrete is increased and the liquidity of concrete is progressively... |
