Investigation on the Expansion Value of Turbine Generator Foundation affected by Alkali-Silica Reaction

It is well known that expansion of concrete is occurred in the concrete structure affected by Alkali-silica reaction in addition to crack propagation. However it is difficult to measure expansion value after the alkali silica reaction occurrence in a structure. The turbine generator foundation which is the core discussion item of this paper has been monitored for expansion values and reinforcement bar strains, upon which the expansion of the structure due to affect of the alkali silica reaction is found out. The total expansion values of the turbine generator foundation due to the affect of Alkali-silica reaction were estimated according to those measurement results in order to be utilized for a turbine generator foundation analysis.
