摘要：
The strength development of 300N/mm2 class ultra-high strength grout by heat-controlled curing was investigated. The strength development at 80-180 ℃ becomes higher than that at a constant temperature of 5-35 ℃, and can be expressed by an effective age based on the same manner. This is because the reactions of C2S, C3A, and C4AF are promoted, and the capillary pores are reduced by heat-controlled curing. Furthermore, it was clarified that heat-controlled curing with a heatingwire system and/or surfaceheatingelements achievedthe samestrength level as that byheat-controlledcuring under sealedconditions due tosimilarwater content. © 2023 Architectural Institute of Japan.
