摘　　要：考虑铁矾渣掺量和水胶比的影响,对铁矾渣混凝土进行配合比试验研究,分析不同配合比条件下铁矾渣混凝土的抗压强度。试验结果表明,随着铁矾渣掺量增加,铁矾渣混凝土的抗压强度减小,利用铁矾渣部分替代水泥制备铁矾渣混凝土时,铁矾渣掺量应在0~20%。当掺入20%铁矾渣时,铁矾渣混凝土的抗压强度随着水胶比的提高先增强后减弱;当掺入30%铁矾渣时,提高水胶比会使铁矾渣混凝土的抗压强度减弱。最后,对试验结果进行回归分析,得出铁钒渣混凝土抗压强度与水胶比之间的关系。Considering the effects of the amount of jarosite slag and water-binder ratio,the proportional test of the jarosite slag concrete is conducted to analyze the compressive strength of jarosite slag concrete under different proportional conditions.Test results show that,as the content of jarosite slag enlarge,the compressive strength of jarosite slag concrete declines.When the jarosite slag partially replaces the cement to prepare the concrete,the content of the jarosite should be from 0 to 20%.When the content of jarosite slag is 20%,with the raise of water-binder ratio,the compressive strength of jarosite slag concrete is improved first and then reduced.When the content of jarosite slag is 30%,the larger water-binder ratio will reduce the compressive strength of jarosite slag concrete.Finally,the regression analysis of the test results is carried out,and the relationship between compressive strength of jarosite slag concrete and water-binder ratio can be obtained.
