Abstract Based on the drawback of insufficient calcium hydroxide content required for pozzolanic reaction in ultra-high performance concrete (UHPC) incorporating high volume mineral admixtures, hydrated lime was intentionally added into the ultra-high strength concrete (matrix of UHPC) to investigate its influence on the mechanical properties of ultra-high strength concrete. The mechanism for the improvement in mechanical properties of ultra-high strength concrete should be pozzolanic reaction between hydrated lime and mineral admixtures, which formed C-S-H and C-A-S-H gels. Partial C-(A)-S-H gels were transformed into tobermorite and xonotlite crystals under combined curing (90 ℃ hot water curing for 2 d and 250 ℃ dry air heating for 3 d), which improved both the microstructure and mechanical properties of ultra-high strength concrete.

Key words： ultra-high strength concrete hydrated lime mechanical property mechanism
