With the wide application of manufacture sand self-compacting concrete, the applicability of the existing creep prediction model formula to the creep prediction of manufacture sand concrete needs to be improved. On the basis of ACI-209R model, the water-powder ratio and the influence coefficient of limestone powder are introduced. The test results are in good agreement with the calculated data, which provides data support for guiding practical engineering applications.

摘要

With the wide application of manufacture sand self-compacting concrete, the applicability of the existing creep prediction model formula to the creep prediction of manufacture sand concrete needs to be improved. On the basis of ACI-209R model, the water-powder ratio and the influence coefficient of limestone powder are introduced. The test results are in good agreement with the calculated data, which provides data support for guiding practical engineering applications.
