| Abstract: | According to the strict quality requirements of warped surface concrete construction in south-to-north water diversion,the influence of controlled permeability formwork liner to the mechanical properties and surface permeability of concrete are studied.The results show that controlled permeability formwork liner can significantly improve the appearance of concrete and the surface mechanical properties,and the surface permeability of concrete decreases significantly.Controlled permeability formwork liner can effectively improve the surface properties of concrete,and concrete structure has a good durability. |
