Water - Cementitious Material Ratio For Coastal Construction
Water - Cementitious Material Ratio For Coastal Construction
(OP)
Are structures located on the coast considered to be subject to "sea spray" and therefore subject to section 4.2.2 of ACI 318?

PCA carried out a long term study on the effects of seawater on reinforced concrete http://www.cement.org/pdf_files/CT012sea.pdf
About the concrete mixtures for this environment. I wonder if fly ash or any other cementitious material is used, and if so, how much cement replacement is permitted? And the admixtures..what's commonly used?

I go a step further by adding corrosion prohibitors to the concrete mix. It is cheaper to have proper mix than coming back and repairing spalling concrete.

Do the concrete mixtures require air-entrainment?
