Research Brief: A Reaction-Diffusion Model to Determine Mesoscale Patterns in Cement Paste
(2018-08)
Strength and toughness, two important aspects of the durability of concrete structures, are dramatically influenced by the material’s nanotexture, but the question of how the building blocks of cement paste organize ...
Research Brief: Modeling the Freeze-Thaw Damage Mechanism in Cement
(2019-01)
Freeze-thaw (FT) damage is a significant threat to roads and pavement, yet the underlying mechanism is still unclear. Conventional thinking attributes the damage to pressure generated by expansion of water upon freezing. ...
A Scientific Investigation into Concrete Pavement Durability
(MIT Concrete Sustainability Hub, Oregon State University, University of New Brunswick, 2021-01)
Although concrete pavements offer many long-term performance benefits, there are still instances where premature degradation of pavements leads to unexpected and costly repairs. In addition to being a burden to transportation ...
Research Brief: Capillary Stress During Cement Drying Shrinkage
(2018-06)
Imagine a household sponge lying next to a kitchen sink. The sponge looks and feels different when it is wet versus when it is dry. When a sponge dries, it shrinks, curls and hardens due to suction forces (called “capillary ...
