摘要：In the construction industry today, there is a need for improved testing procedures capable of accurately predicting the susceptibility of aggregates to the alkali-silica reaction (ASR). These new procedures will permit the use of some aggregates that have been excluded in the past on the basis of being classified as reactive. Effective mitigation methods will permit the economic use of reactive aggregates that would normally be excluded. Increasing the quality of the aggregate sources the target of this research, the results of which will help manufacturers sell more products while cutting prices for consumers. By modifying ASTM C1260, we expanded the length of testing from 14 to 56 days, changed the water content of the mixing proportion with the water to cement ratio controlled at 0.47, the molarity of the curing solution, and used different interpretation methods, specifically Avrami′s model and the polynomial fit procedures. If the results of this research enabled even 25 percent of these materials to be used, the increased volume available for use would increase substantially.
