When acid attack concrete it, dissolves, both, hydrated, and, un-hydrated cement, compounds as well as calcareous aggregates. In many of the cases the chemical reaction results in water soluble calcium compounds which are leached away. Concrete vulnerability to acid attack increases as the pH of the acid in contact decreases from 6.5.

Concrete, is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. In the past, lime based cement binders, such as lime putty, were often used but sometimes with other hydraulic cements, such as a calcium aluminate cement or with Portland cement to form Portland cement ,concrete, (named for its visual ...

standardsarepresented. From the literature it is seen that, the reaction ,between water, and cement affect the setting time, compressive strength and also lead to softening of ,concrete,. All the impurities may not have adverse effect on the properties of ,concrete,. The use of

Aggregate Reaction - an overview | ScienceDirect Topics
Aggregate Reaction - an overview | ScienceDirect Topics

The alkali-aggregate reaction of ,concrete, is that alkalis (Na 2 O and K 2 O) in cement react with active silicon dioxide in aggregate to generate alkali-silicic ,acid, gel on the surface of aggregate. This gel has the property of wet swelling. When it swells, the cement paste surrounding aggregate expands and cracks. Such phenomenon that damages ,concrete, is called alkali-aggregate reaction.
