Abstract
Prefabricated Bridge Element and System (PBES) construction commonly relies on field-cast grout-type materials to complete the connections between precast concrete elements. The interface bond between the grout and the substrate concrete can be a key factor in the long-term durability of the structural system. This paper evaluates bond performance of a non-shrink cementitious grout, and how the supply of extra moisture at the grout-concrete interface affects the bond strength. The results show increased bond strength when extra moisture is provided.
