Abstract: Low calcium and high strength clinker cement concrete was prepared by using low calcium and high strength clinker cement and gravel as raw materials. The freeze-thaw test and freeze-thaw - dissolution test of concrete were carried out by using the method of rapid freezing and thawing and solution soaking to simulate a soft water environment at low temperatures.The damage law of low calcium and high strength clinker concrete under single freeze-thaw and freeze-thaw dissolution were calculated based on the concrete mass loss rate, relative dynamic elastic modulus, and calcium ion dissolution rate which are the damage index of the concrete.SEM and the nitrogen adsorption method were used to examine the microstructure of the concrete’s deterioration evolution. The concrete damage model under freeze-thaw and corrosion is established, and the failure probability of concrete is discussed, all based on the Weibull distribution theory. The results show that compared with ordinary cement concrete, the mass loss rate of low calcium and high strength clinker concrete under freeze-thaw cycle and corrosion is larger, but the relative loss of dynamic elastic modulus and the dissolution rate of calcium ions are smaller, and the microstructure damage is smaller is also smaller. The change in the degree of damage of three factors for two types of concrete corresponds to the Weibull distribution model. Under the same freezing and thawing frequency, the low calcium and high strength clinker cement concrete showed better freezing resistance and corrosion resistance than ordinary cement concrete.
