Self-compacting concrete is a new type of high-performance concrete , it has excellent deformability and segregation resistance , can fully rely on its own weight in the casting process flowing freely , but also has sufficient cohesion to prevent segregation bleeding uniform mixture compacting , after hardening has good mechanical and durability . A lot of problems for self-compacting concrete complex composition , rheological and work factors , we first study the superplasticizer with cement and mineral admixture compatibility issues , and rotational viscosity meter cement paste the rheological parameter explore the reducing agent, the type and dosage of mineral admixtures on the rheological properties of cement paste . On this basis , research admixtures, mineral admixtures on rheological properties of self-compacting concrete , workability and strength . Experimental results show that the cement paste fluidity and rheological parameters there is a good correlation between self - compacting concrete work , paste fluidity and rheological parameters can be used to guide the self-compacting concrete mixture ratio design . Superplasticizer can reduce the plastic viscosity of the slurry η yield shear stress τ0, self-compacting concrete rheology and working to improve the favorable effect of polycarboxylate superplasticizer best , the best content in about 1.0% . The right amount of fly ash, slag incorporation can improve the rheology and workability of self-compacting concrete , fly ash content of 30% , the best content of the slag is 15% . The combined use of fly ash, slag appropriate proportion , can play a \
