| Abstract: | This research optimally selects the concrete using raw materials in optimum mixing proportion,and the following experiments are conducted for the optimally-selected concrete:slump degree,dispersion degree,passing capacity of gaps,anti-separation property and compressive strength.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 their poor qualities. |

| Keywords: | self-compacted concrete preparation optimum selection of raw materials workability |
