In this paper, the influence of limestone powder size and content on the compressive strength and transportation performance of self compacting concrete was studied. The weight of SCC mixture cement and 1015 were prepared by using F grade fly ash with uniform moisture content of 045 and 475 kgm3 instead of 20% of F grade fly ash

The strength of limestone macadam aggregate is affected by the content of graded fine material and dust content. Both the atberg limit and dust content of aggregate gradation fine aggregate will affect the quality. The fine content is the percentage passing the No. 200 sieve, while the dust ratio is the ratio of the percentage passing through the No. 200 sieve
