One of the major weaknesses of concrete is its reduced chemical resistance, especially to acids. To what extent can resistance to acid attack be improved by the use of crystallisation admixtures, or are surface protection membranes the only real option?ç

In this article, our expert Albert Berenguel explains:

• The formation of calcium hydroxide during the hardening of Portland cement
• The benefits of the addition of admixtures to reduce porosity.
• How crystallisation admixtures reduce concrete porosity and seal cracks.
• The limits of chemical resistance of improved concrete when pH decreases below 3.
• Why even the best concrete will probably need a waterproofing membrane.
