Abstract
The paper researched the workability of the concrete influenced by the fly ash quantity mixed.The research results showed that within the 40% quantity of the fly ash mixed,as the fly ash mixed increased,the fluidity of the concrete will be increased and the fly-ash mixed can obviously improve the slump timing loss of the concrete.The paper analyzed the influence mechanism of the fly ash to the workability of the concrete.
