| Abstract: | Strength and deformation of concrete can develop with its ages. According to the result of laboratory tests, the relationships among compressive strength, tensile strength, elasticity modulus, tensibility limit, drying shrinkage, etc and its ages are studied. The differences of conventional concrete and roller compacted concrete are compared. The results show that ability resistance fissure of roller compacted concrete is better than that of conventional concrete. |
