Alkali Reaction of Aggregates | Building Materials | Concrete Technology
Till 1940, aggregates were considered as inert materials, but after 1940, it has been clearly established that aggregates are not fully inert. Some of the aggregates contain reactive silica which reacts with the alkalis (Sodium oxide Na2O and potassium oxide K2O) present in cement. For the first time in U.S.A. it was observed that many failures of concrete structures as [...]
