Research Brief: Mechanical properties of Alkali Silica gels
August 17, 2017

Certain aggregates that are used to make concrete contain amorphous silica. This silica can react with alkalies in the cement paste pore solution and form a gel. This reaction is called alkali-...

Research Brief: Atomistic Modeling of ASR Gel
August 14, 2017

The Alkali-Silica Reaction (ASR) causes expansion and cracking in concrete which can result in structural problems in concrete infrastructure. ASR gel, formed from a chemical reaction between...

Research Brief: Minimizing Thermal Cracking in Concrete Pavements
November 30, 2016

Stresses resulting from thermal cycles within concrete pavements can cause expansion, contraction, bending, and flexing that can lead to fracture. This brief examines the risk of fracture of...

Research Summary: Lowering Vehicle Fuel Consumption and Emissions Through Better Pavement Design and Maintenance
October 27, 2016

Pavement-vehicle interaction (PVI) describes the interaction between a vehicle’s tires and the roadway surface it is driving on. Our team has developed models that quantify excess fuel consumption...

Research Brief: Examining Freeze-Thaw Damage at the Microscopic Scalee
Research Brief: Examining Freeze-Thaw Damage at the Microscopic Scale
August 31, 2016

Freeze-thaw damage is a potentially serious deterioration process that occurs in concrete structures in cold climates. While it is known that using certain deicing salts can aggravate the damage,...

Research Brief: Two-Phase Model of Pavement Fracture
June 2, 2016

CSHub researchers are working to understand pavement fracture at all levels, from the nano-scale up, so it is important to have a model that allows for the evaluation of cracks as they are forming...

Research Brief: Bottom-up Modeling of ASR in Concrete
March 30, 2016

Alkali–silica reaction (ASR) occurs in some concretes between the highly alkaline pore solution and reactive silica components of certain aggregates. An alkali-silica gel forms that may expand...

Research Brief: Modeling Freeze-Thaw in Concrete
May 22, 2015

Damage to concrete slabs during freezing and thawing cycles represents a major challenge to pavement durability and resilience. This brief explores freeze-thaw cycles in concrete using models that...
