Green high durability concrete (Green high durable concrete, GHDC), in recent years in the Green High Performance Concrete (GHPC), high performance expansive concrete, hybrid fiber reinforced concrete, based on the development of a both a high durability (high impermeability, frost resistance and corrosion resistance), high operating and economic applicability, but also has environmental protection, energy conservation, sustainable development beneficial to the community new concrete. This paper was prepared by seven major series 19 set mix concrete, and based on the results of plastic shrinkage cracking test, preferably a GHDC typical mix, prepared with different intensity levels GHDC. Durability of concrete for the current research trends, the role of the freeze-thaw cycle, 35% of the external bending stress, NaCl solution erosion, MgSO4 solution erosion, (MgCl2 and Na2SO4) complex solution erosion factors, carried out in a single freezing and thawing of concrete, double (35% of the bending stress freezing and thawing, freezing and thawing 10% NaCl, freezing and thawing 5% MgSO4, freezing and thawing 5% MgCl2 5% Na2SO4) role and multiple factors (freeze 35% bending stress 10% NaCl, 35% of bending thaw Stress 5% MgSO4, freezing 35% bending stress 5% MgCl2 5% Na2SO4) factors under the action of frost resistance test. Mainly studied the large volume mineral admixtures (fly ash, slag and silica fume), water-cement ratio, admixtures (efficient air-entraining agents, bulking agents) multi-composite, hybrid fiber reinforced, corrosion solution and external bending stress, etc. factors on the concrete impact of freeze-thaw damage and freeze-thaw damage analysis, development and suppression rules, freeze-thaw damage of concrete on the inhibition of the law was investigated experimentally. Mainly the following conclusions: (1) 35% external bending stress accelerates the deterioration of concrete freezing and thawing process of the degree of injury, in the actual use of the environment of concrete should pay full attention to the role of stress. (2) Concrete in a salt solution of the dual and multiple factors are below freezing injury factors, the extent of damage a single freeze-thaw cycles; concrete at different salt environments thaw longevity are: complex solution (5% MgCl2 5% Na2SO4)> 5% MgSO4> 10% NaCl. (3) water-cement ratio decreases and the large volume mineral admixtures (fly ash slag, silica fume), in (freeze 10% NaCl) and (freeze-thaw 5% MgSO4) under the action of the dual factors inhibiting freezing and thawing of concrete injury had no significant effect; thaw in a single factor (freeze-thaw stress) and (freeze-thaw complex solution) under the action can significantly improve the frost resistance of concrete and corrosion of concrete frost resistance and corrosion resistance have been improved to some extent. (4) Admixture (expanders entraining agent) and hybrid fiber reinforced composites produced multiple freeze-thaw damage inhibiting compound effect, inhibiting concrete freeze-thaw damage effect is very obvious, so that resistance to freeze-thaw damage of concrete stronger, freeze-thaw resistance of concrete damage of life is greatly improved. (5) through regression analysis of experimental data obtained under test conditions thaw damage of concrete failure process mathematical model. (6) In practice, various measures should be based on the characteristics of freeze-thaw damage to different environments use different measures, mixing various additives, using appropriate hybrid fiber in proportion to freeze-thaw damage to inhibit, enhance resistance of concrete freezing of the best results.
