The phrase "aggregate reaction" is correct and usable in written English.
It can be used in contexts related to chemistry, biology, or data analysis where multiple reactions or responses are combined into a single measure or outcome.
Example: "The aggregate reaction of the participants indicated a strong preference for the new product design."
Alternatives: "combined response" or "overall reaction".
Alkali aggregate reaction (AAR) affects numerous civil engineering structures and causes irreversible expansion and cracking.
The principle modes of repair failure were cracking (32%%), debonding (25%%), continued corrosion of embedded reinforcement (22%%), alkali aggregate reaction (4 %) and others (17%%).
Fly ash was initially used in concrete as an admixture to enhance rheological properties and reduce the alkali aggregate reaction (Mindess and Young 1981).
Whereas many publications report on alkali aggregate reaction (AAR) expansion or test analyses, very few address the more pressing issue of its impact on structures.
Alkali Aggregate Reaction (AAR) and Delayed Ettringite Formation (DEF) cause expansion of the affected concrete that generally leads to cracking and decrease of its mechanical properties.
Lithium salts are known to have remarkable effect to restrain alkali aggregate reaction, but the influence on strength and setting time of cement paste is uncertain.
Alkali-aggregate reaction can damage concrete.
In terms of durability, alkali-aggregate reaction, carbonation, shrinkage, and chloride and sulfate resistances, were investigated.
Over the past years, several tools were developed to provide diagnostic and prognostic assessment of concrete structures, especially those affected by Alkali-Aggregate Reaction (AAR).
The alkali-aggregate reaction and the internal sulfate attack are two chemical reactions that lead to expansions in concrete structures.
Regarding durability, mixtures with the high free lime fly ash led to higher expansion due to alkali-aggregate reaction.
