| Abstract: | In view of the disadvantages of alkali-aggregate reaction,salt out low adaptability to cement induced by the accelerators containing sodium salt and kalium salt for early strength of concrete,ZQ-1 Na+ & K+-Free Concrete Early Strength Accelerator was developed based on the tests by way of orthogonal design and effects of various factors on early strength of the concrete were analysed.All the indexes for the accelerator attainted to and exceeded requirements set in the current national standard. |
