Research on Mechanical Properties of C100 High-Strength Concrete Used for Frozen Shaft
The mechanical properties of C100 high-strength concrete used for frozen shaft were studied in this research. The results demonstrate that: The cementitious materials 570 kg/m3 concrete 28 strength is only 104.5 MPa, which is lower than the C100 requirements; the early strength (3d) of the concrete doped with 30% admixture is less than 20% admixture concrete, but with the age increase, its strength gradually reaches close to concrete doped with 20% admixture, and eventually exceeds the concrete doped with 20% admixture. The tension-compression of high strength concrete doped with 15% fly ash and 15% slag is the smallest, while the tension-compression of the concrete doped 10% fly ash and 10% slag reaches the maximum. The Poisson's ratio of C100 concrete is between 0.20 and 0.24; the compressive elastic modulus is about 50 GPa; and the tensile elastic modulus is about 110 GPa.
