The mathematical relationship between fiber-matrix interfacial shear stress and drying shrinkage reduction due to fiber addition was derived for the purpose of estimating this stress from the measured drying shrinkage of short fiber reinforced cement. For short carbon fiber reinforced mortar, this stress increased with curing age, particularly abruptly within the first 2 days and reaching 1.92 MPa at 14 days if slip between fiber and matrix was assumed and 3.46 MPa if no slip between fiber and matrix was assumed.
