Research Brief: Examining Freeze-Thaw Damage at the Microscopic Scale
(2017-01-12)
Researchers conducted both theoretical and numerical studies on the microscopic phenomena in cement paste pores to reveal the important roles that ions and electrolytes play in freeze-thaw damage.
Research Brief: A break-even hazard mitigation metric
(2017-01-12)
CSHub researchers developed the Break Even Mitigation Percent (BEMP) to answer the question: “How much should be invested in mitigation for a particular building?”
The Effects of Inflation and Its Volatility on the Choice of Construction Alternatives
(MIT Concrete Sustainability Hub, 2011-08)
Life Cycle Cost Analysis (LCCA) is the standard method for costing long-lived construction projects. The LCCA process determines the full costs of mutually exclusive construction options, finding the project design with ...
Critical Issues When Comparing Whole Building & Building Product Environmental Performance
(2016-10-17)
Guides, standards, product category rules, and environmental product declarations have emerged to evaluate environmental impacts within the buildings sector. These efforts have certainly moved the field forward, but as of ...
Research Brief: Validation of Molecular Dynamics-Based Structural Damage
(2019-03)
Windstorms currently generate $28 billion in average annual damage and this figure is projected to potentially rise to $38 billion by 2075. Traditional engineering approaches that analyze the resilience of structures fail ...
Research Brief: Concrete building design optimization for reduced life cycle costs and environmental impacts
(2018-04)
Decisions made at early stages of the building design process can have a large influence on the environmental performance and financial costs of a building. One of the best ways to discover preferable designs is to analyze ...
Research Brief: Implications of energy code evolution on energy performance of multi-family residential buildings in the US
(2018-03)
The International Energy Conservation Code (IECC), which is created by the International Code Council (ICC), standardizes expectations for the design and construction of buildings with regards to energy use and conservation ...
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: Simulating the Formation of ASR Gels
(2019-04)
Alkali-silica-reaction (ASR) is a significant cause of premature concrete deterioration. Although it has received much research attention, an essential question still remains—how does a soft gel, as is formed by this ...
Research Brief: Meeting Greenhouse Gas Reduction Targets in the Building Sector
(2019-07)
As the threat of climate change grows, lowering the greenhouse gas (GHG) emissions of high emitting sectors of the economy has become critical. The buildings sector is particularly significant, consuming up to 40% of total ...
