Comprehensive modeling of chloride ion and water ingress ...

The chloride ion convection by water is controlled by water vapor and liquid water movement. The chloride ion convection in capillary liquid water suction is the fastest process for propagating the chloride ion front in the cover concrete , .Water vapor movement and the chloride ion convection are respectively modeled with Fick's diffusion equation and with the kinetics Eq.

Strength and Permeability Characteristics Study of Self ...

Self-compacting concrete (SCC) is one of the most significant advances in concrete technology over the past two decades. SCC was developed to ensure adequate compaction through self-consolidation and facilitate placement of concrete in structures with congested reinforcement and in restricted areas. This paper aims to focus permeability study of self-compacting concrete (SCC) made with ...

Chemical recycling and use of various types of concrete waste ...

1. Introduction. Concrete is one of the most widely used materials globally with water being the only material that is used in larger quantities (Xuan et al., 2018).The International Energy Agency reported that ∼25 Gt of concrete is used each year globally (WBCSD and IEA, 2009), which is equivalent to > 3.8 t of concrete per person per year (Petek Gursel et al., 2014).
