This paper proceeds some discussion about the optimized sand-ratio, ave rage paste thickness and aggregate packing degree in the packing concrete mix proportion design.

Construction-Quality manipulation of low-intensity self-compacting concrete used in the vertical thin member;

Applied analysis of low-intensity self-compacting concrete at the vertical thin member;

The states on research and the developing foreground of self-compacting concrete;

Parameter method for mix design of self-compacting concrete;

Mechanical properties of self-compacting concrete;

The abundant data reveals that,after appropriate mixing,the artificially machine-made sand and crushed artificial gravels in Guizhou area can prepare the self-compacted concrete which satisfies the requests of projects in spite of t.

Based on the investigation on the workability of fiber reinforced self-compacted concrete (FRSCC), this paper analysed the influence of the types of fibers, including steel fiber, polypropylene fiber and hybrid fiber, on the compressive strength and flexural toughness according to different international guidelines.
