摘　　要：在简化权重成熟度法的基础上改进成快速简化权重成熟度法,仅需3 d即可准确预测混凝土21 d龄期内的早期抗压强度,92.6%的（预测值实测值）在0.9~1.1的范围内,（预测值实测值）的均值为0.99,变异系数为7.7%。A new accelerated test method that based on simplified method of the weighted maturity is developed to predict the early - age compressive strength of the concretes in 3 days. The results show the new method can accurately predict concrete strength, which （predicted value）/（ measured strength）is 92.6%in the range of 0.9 to 1.1, the mean is 0.99 and the COV.is 7.7%.
