Abstract: In this paper, a study on the use of limestone powder (LP) as fillers in self compacting concrete (SCC) and their effects on the strength and shrinkage of concrete aggregate are presented. The application of limestone powder has already brought a great improvement for strength and shrinkage properties of SCC. Besides, the use of limestone powder as building material promoted an interesting possibility for the use of secondary raw materials in the construction industry.
An experimental program was conducted on artificial sand and the high range water reduce admixture "JM-PCA-II".
The results indicated that the appearance of limestone powder in artificial sand, aggregate grading, etc. has significant effects on the improvement of the strength and shrinkage property of SCC.
It is recommended by authors that the ratio of limestone powder in artificial sand should be about 18%. For this ratio of limestone powder, the compressive strength of SCC is increased approximately 12% at 28 days, and the shrinkage properties of SCC is also improved a lot.
