几种外加剂组分对硫铝酸盐水泥性能的影响
Influence of additives on properties of sulphoalu minate ce ment
摘要
Abstract
By the way of adding admixtures to the sulphoaluminate cement,the study is performed to find a kind of material to repair the airport concrete pavement during the war in an hour.Through studying the influence of different contents of a single component,such as lithium carbonate,calcium nitrite,polycarboxylate superplasti-cizer,calcium carbonate,silica fume,on different performance of the sulphoaluminate cement,the best single component dosage range was obtained.The paper used orthogonal test to investigate the effects of sulphoalumi-nate cement mortar strength on different dosage of composite components under the standard curing conditions. The results indicate the best ration of super -early -strength admixture and the content of lithium carbonate,sil-ica fume,polycarboxylate superplasticizer,calcium nitrite,nano calcium was respectively 0.1%,4%,1.0%, 0.5%,0.5%.When the best ratio of admixtures was added,the material’s 1 h mortar flexural /compressive strength reaches 6.2 /37.1MPa,and its 3 d mortar flexural /compressive strength reaches 10.8 /62.3 MPa,which meets the requirement of wartime runway repairs.关键词
