Wash water is generated as a by-product of ready mixed concrete production. Reuse of the water as mixture water is limited, in practice, by the negative material performance impacts associated with the water chemistry and suspended solids (i.e. hydra

Fly ash, a solid waste generated from coal burning, can replace up to 70% of the cement in concrete and reduce environmental impact, cost of construction, and power generation. However, the lack of fly ash adsorption capacity measurement tools limits

The adsorption of air-entraining admixtures (AEAs) on coal fly ash was evaluated and quantified using adsorption isotherm experiments. The interaction between AEAs and aggregate, cement, and fly ash were studied, and the physical and chemical process

This study evaluated the impacts of construction on the air content and air void system structure of portland cement concrete pavements. The primary intent was to quantify the air content of fresh concrete before and after it had gone through the sli

The combination of chloride deicer exposure and temperatures near the freezing point of water makes for an aggressive environment for many concrete pavements and bridge decks. In laboratory-simulated conditions, the formation of calcium oxychloride h

Several automated procedures for the characterization of the air-void system of hardened concrete rely on a contrast enhancement step to make air-voids appear white and aggregates and paste appear black. Pixels in the digital image darker than a sele

Carbon sequestration through the formation of carbonates is a potential means to reduce CO2 emissions. Alkaline industrial solid wastes typically have high mass fractions of reactive oxides that may not require preprocessing, making them an attractiv
