Abstract：Based on the load-bearing states of mortar and coarse aggregate under the peak compressive stress of concrete,hypotheses regarding the stress distribution between coarse aggregate and mortar were proposed.A prediction model for the compressive strength of high-strength concrete,featuring series-parallel connection based on the elastic modulus,was established and validated using C60 high-strength concrete.The results indicate that the error between the predicted and measured compressive strengths of concrete with granite and dolomite coarse aggregates is within 10%.This model can provide a reference for determining the early tensile age of prestressed concrete members and controlling structural deformation in the later stages.
