Abstract: Monolithic six-side permeable frame is a traditional revetment structure, but its end steel bar is susceptible to corrosion.To solve this problem, the self-compacting steel fiber reinforced concrete was used to replace the traditional concrete, and the internal steel bar of the frame was canceled, and the preparation test of self-compacting steel fiber reinforced concrete for the permeable frame was carried out.The raw materials of the project site was used, the coefficient value in the formula of water-binder ratio was determined by the mix design and test of matrix self-compacting concrete, and the formula for predicting the strength of concrete with different water-binder ratio at early age was obtained.Then, the mixture ratios of C25 self-compacting steel fiber reinforced concrete with fiber volume ratios of 0.4%,0.8% and 1.2% were determined by the direct calculation method of mixture ratio, and the working performance and the compressive strength of the mixture at 7 d and 28 d curing ages were measured by experiments.At last, the trial production of self-compacting steel fiber reinforced concrete for monolithic six-side permeable frame was carried out by using the integral forming technology, which verified the practicability and reliability of this technology.
