Filtering Effect of Textile Form Method

Concreting Technique using a Special Textile with Formwork

Abstract

Deterioration in the durability of concrete structures, which is mainly caused by saline permeation, freezing and thawing actions and carbonation of concrete, has recently become a social problem, and it has been required to further improve the structural durability of concrete.
This paper describes a newly developed concreting method, “Textile Form Method”, using a special textile having high permeability of aeration effects. In this method, excess water and entrapped air are bled out of the textile form, hereby improving structural durability of concrete and producing concrete with higher density toward the surface free from air bubbles and blow holes.
The above improvement have been proved by filtering effect of geotextile and the method has been attracting the attention as a new field of concrete textiles.
