concrete

This paper introduces a cohesive, unified dataset of material, energy, and emission inventories to quantify the environmental impacts of concrete, details the synthesis of this open dataset, and creates an environmental impact assessment tool using this data.

In this work, a literature review of key parameters that can facilitate desired CO2 uptake for transportation projects at their end of life is conducted and an initial meta-analyses of data from the literature to inform CO2 uptake for individual projects is performed.

Concrete is also responsible for over 8% of annual anthropogenic greenhouse gas (GHG) emissions globally. As population and urbanization increase and existing infrastructure deteriorates, demand for production of concrete will increase, and with it, the environmental burdens from its production. The models used to determine environmental impacts of producing concrete have considerable uncertainty and variability. This makes it challenging to identify the most effective means of mitigating these burdens.

This work aims to quantitatively examine data variability, an inherent characteristic of elements in supply chains, and data uncertainty, a function of data quality for the system being modeled, in assessments of greenhouse gas and air pollutant emissions from concrete production.

This report demonstrates how considerations across concrete material design and infrastructure design can be used together to change environmental impacts and costs by targeting appropriate constituents, materials, and system longevity.
