Abstract

Una mezcla para composiciones cementosas para mitigar la reacción álcali-sílice (ASR) que incluye partículas mitigantes de la reacción álcali-sílice que están en contra de la aglomeración. El aditivo puede proporcionarse en una composición de mezcla líquida acuosa para composiciones cementosas que incluye el aditivo mitigante de la reacción álcali-sílice, un agente espesante y agua. La mezcla utiliza un espesante sensible al pH en combinación con un ajuste del pH para estabilizar las partículas del aditivo mitigante de la reacción álcali-sílice contra la aglomeración. La composición de mezcla se usa para mitigar las reacciones álcali-sílice en una composición cementosa. También se describen métodos para preparar la mezcla, composiciones cementosas y estructuras cementosas endurecidas.
