The research is about superfine sand and superfine sand concrete according to the status of big yield of superfine sand in middle and downstream area in Liao River and demanding prompt exploitation. The article used the concrete made of superfine sand of Liao River as the research object, discussed the mixing proportion of superfine sand concrete of Liao River by orthogonal experiment. The result shows that the optimal mixing proportion of C25 superfine sand concrete is water cement ratio 0.55、sand ratio 25% and the content of water reducer 0.8%.
