Research on Controlled Permeability Formwork of Nonwoven Fabrics to Retain the Humidity on the Concrete Surface

Abstract:

It is of great significance for concrete to be cured using controlled permeability formwork of nonwoven fabrics especially in dry area. CPF can improve durability of concrete through decreasing the ratio of water and cement in concrete surface. CPF could also retain the water within it. The role of concrete curing using CPF or not is test by MOIST200B type microwave moisture meter. In addition, the permeability of concrete surface between the concrete which use CPF or not is analyzed through the air permeability test, the initial surface absorption of concrete test (ISAT). The testing results indicate that there is little effect on curing of concrete using controlled permeability formwork liner.
