Abstract:

Traditional concept thought that medium sand and fine sand can be used to mix concrete, superfine sand can not used to mix concrete. This makes the source of superfine sand limited. With the shortage of medium sand and fine sand, it is imperative to exploit the resource of superfine sand. Superfine sand concrete is mixed by means of Double-doped Technology-ultra-fine fly ash and super plasticizer. Primary factor influencing superfine sand concrete strength is studied by orthogonal test, the optimal mixture ratio is found. The results indicated that the primary factors are water-binder ratio and sand ratio. At the same time, the workability and strength of superfine sand concrete mixed by optimal mixture ratio can satisfy the quality request of general engineering. It is proved that the double-doped technology is feasible, which can be used to conduct engineering construction.
