Leaching

Structures such as dam where the flow of water via pores of concrete is high, there could be significant loss of mono-sulfate and ettringite and decalcification of calcium silicate hydrate due to leaching out of these salts to the surface and subsequently washing away. This will lead to reduction in strength of concrete and increases … Continue reading Leaching

Durability of concrete in terms of water permeability

Permeability is one of the main indicator defining the durability of the concrete.  In one hand, the permeability of the concrete can be high from the beginning of concrete life, in which case, the deterioration takes place rapidly during the service life. While in the  other hand, the permeability of the concrete may gradually increases … Continue reading Durability of concrete in terms of water permeability
