METHOD FOR PREDICTING DRYING SHRINKAGE STRAIN OF CONCRETE
PROBLEM TO BE SOLVED: To provide a method for predicting a drying shrinkage strain of concrete, requiring no measurement of Young's modulus of coarse aggregate and a drying shrinkage strain, without a need of using a recommended value of fine aggregate.SOLUTION: A method for predicting a drying shrinkage strain of concrete includes: a first calculation process for calculating a final value of a drying shrinkage strain and Young's modulus of fine aggregate and coarse aggregate, using water absorption of the fine aggregate and the coarse aggregate, and a formula a and a formula b1 or b2; and a second calculation process for calculating a prediction value of the final value of the drying shrinkage strain of concrete, using the value calculated in the first calculation process.SELECTED DRAWING: Figure 4
