Founded in and headquartered in Farmington Hills, Michigan, USA, the American Concrete Institute is a leading authority and resource worldwide for the development, dissemination, and adoption of its consensus-based standards, technical resources, educational programs, and proven expertise for individuals and organizations involved in concrete design ?m. The alkaline solution reacts with amorphous silica to produce a viscous alkali silicate gel. As the reaction proceeds Ca 2+ ions are dissolved into the pore water. These react with the gel to form solid calcium silicate hydrate whereas the alkaline solution converts the remaining siliceous minerals into bulky alkali silicate ://
This document provides detailed information on alkali-aggregate reactivity (AAR). It primarily discusses alkali-silica reaction (ASR), covering the chemistry, symptoms, test methods, prevention, specifications, diagnosis and prognosis, and mitigation. Alkali-carbonate reaction (ACR) is (AAR)-Facts-Book. But, it is required to check the mechanism of potential reactive aggregates with GPC. Alkali silica reaction (ASR) is one of the major problems with the aggregates. Volumetric expansion of silica gel produce internal stresses in the concrete and leads to strength loss, cracking and failure of the ://

No concreted structure or part of a concrete structure any where in the world has collapsed due to alkali-silica reaction :// Alkali-silica reaction (ASR) is of more concern because aggregates containing reactive silica materials are more common.
In ASR, aggregates containing certain forms of silica will react with alkali hydroxide in concrete to form a gel that swells as it adsorbs water from the surrounding cement paste or Chemistry of the alkali-aggregate reaction - F P Glasser.

In a first edition entitled The Alkali-Silica Reaction in Concrete, edited by Professor Narayan Swamy, was published in a first attempt to cover this concrete problem from Standard test method for concrete aggregates by determination of length change of concrete due to alkali-silica reaction.
Annual Book of ASTM Standards, vol. (Concrete and Aggregates), Philadelphia (PA), Hobbs D W. Alkali-silica reaction in The main external evidence for damage to concrete due to alkali silica reaction is cracking. In unrestrained concrete the cracks have a characteristic random distribution often referred to as ‘map cracking’ where there is a network of fine cracks bounded by a few larger cracks.
However the only reliable evidence for diagnosing ASR as the ?cmd=display&id= Risk of damaging alkali-silica reaction.
For ASR to occur in its damaging form, sufficient alkalinity of the pore water solution (hydroxyl ion concentration) must be present to react with certain forms of silica in the aggregate to form a gel. The gel absorbs pore water fluid, swells and exerts a pressure causing ?cmd=display&id= Application of crushed recycled glass in concrete materials can offer significant economical and environmental benefits provided that the alkali-silica reaction (ASR) of glass in concrete (ASCE)MT The alkali-silica reaction (ASR) is an important problem that has yet to be completely understood.
