Non Newtonian index n, viscous flow activation energy E and comprehensive rheological factor alpha are calculated by second order model regression analysis; STV. The results show that the prepared feeds are pseudoplastic fluid. The binder system was composed of % microcrystalline wax (MW), % high density polyethylene (HDPE) % ethylene vinyl acetate copolymer (EVA) and % stearic acid (SA). The powder loading was vol%. The feed had good comprehensive rheological properties. In order to study the cementitious properties of stainless steel AOD slag, stainless steel AOD slag was used to replace some cement, and its effects on the working properties and mechanical properties of cement mortar were studied. The results show that using stainless steel AOD slag to replace cement from ~ %, with the increase of the content of stainless steel AOD slag, the water consumption of standard consistency of cement first decreases and then increases. When the content is %, the water reduction effect of stainless steel AOD slag is good; With the increase of the content of stainless steel AOD slag, the strength of cement mortar decreases in turn, indicating that the cementitious activity of stainless steel AOD slag is small.

Among them, austenitic stainless steel is marked with numbers of and series. For example, some ordinary austenitic stainless steel is marked with and.The main control load of the platform has high requirements for the shear bearing capacity of the guide leg of the offshore platform. In order to study the factors affecting the shear capacity of the jacket legs of the stainless steel pipe in pipe concrete-filled steel tubular offshore platform, a total of concrete-filled steel tubular shear members were fabricated to study the effects of outer steel pipe material concrete strength, void ratio and shear span ratio on the shear capacity of concrete-filled steel tubular in pipe. It is found that the shear strength of members increases with the decrease of void ratio and the increase of concrete strength; The larger the shear span ratio, the smaller the shear strength. Combined with the test, the empirical formula of shear capacity of concrete-filled steel tubular in pipe is proposed, which is analyzed and verified by ABAQUS finite element modeling software. The results show that the simulation is in good agreement with the test results. In order to study the axial compression performance of stainless steel tube concrete conduit leg and the axial compression performance of stainless steel concrete conduit leg, experiments are used to verify the correctness of the finite element model. The load displacement curves of specimens in groups were compared, and the effects of different void ratio, diameter thickness ratio and bone index on the axial compression performance of concrete-filled stainless steel tubular short columns under axial compression were analyzed. The results show that with the increase of concrete strength, the bearing capacity of specimens increases, but the ductility of specimens decreases; With the increase of void ratio and diameter thickness ratio, the bearing capacity of the specimen decreases; The bearing capacity of stainless steel tube concrete can be effectively improved by adding steel bone; Increasing the bone matching index of steel bone can improve the bearing capacity of the specimen. Based on the jacket offshore platform,Bruntal304 stainless steel pipe, it is proposed to replace the four hollow steel conduit legs of the original offshore platform with concrete-filled steel tube in stainless steel tube to form a new composite offshore platform with concrete-filled steel tube in stainless steel tube, so as to improve the ice resistance and disaster prevention ability of the offshore platform. The scale test on the offshore platform shows that the composite offshore platform of concrete filled steel tubular in stainless steel pipe (hereinafter referred to as the composite offshore platform) has better anti icing performance than the ordinary jacket offshore platform. Taking push as an example, the peak acceleration and displacement of the upper deck of the composite offshore platform of concrete filled steel tubular in stainless steel pipe are reduced by % and % respectively. The analysis of ABAQUS finite element and experimental simulation results shows that the error of the two results can be basically within %.
