Abstract


Along with the development of the construction industry,HPC is appearing in the public eyes.In recent years,it has rapid development in China.HPC most notable feature is its durability ordinary concrete 2-10 times.The main reason for the concrete of achieving high performance is concrete admixture replace part of cement in traditional concrete.The concrete strength in meeting the conditions,while improving the durability,and lower costs,with fly ash and slag powder or ash is the most commonly used,most economic compound admixture.Fly ash concrete to improve late in the strength,but lower intensity early,and the addition of slag powder or ash on the fly ash to make up for this drawback.In addition,the cost of fly ash and slag cement or ash is much lower than cement.The main content of the subject is mastering several Dalian plant emissions of fly ash and slag characteristics according of Experimental study,Discussion on the use of fly ash and slag powder or ash production of composite concrete admixture with the best ratio,that the compound in the concrete admixture of the properties of concrete and concrete with different strength levels can be adding the appropriate Addition to effectively guide admixtures in concrete mixing plant applications.So that the complex admixture of concrete in the construction of the full use of.
