Carbon Footprint

Oral Presentation

With the cement technology moving towards low embodied CO2 cements, optimization of ternary binders composed of Portland cement (PC)-Calcium aluminate cement (CAC) and calcium sulfate (C$) that meet the sustainability need becomes relevant. Previous reports demonstrate that replacement of CAC by slag, silica fume or fly ash hinders the conversion process. However, the incorporation of SCMs in...

4. Development of temperature-dependent phase composition during hydration of ternary OPC-CAC-C$ mixtures with two different CAC types

CAC as an Accelerator for OPC (or other cements)

Oral Presentation

Ternary mixtures composed of calcium aluminate cement (CAC), Portland cement (OPC) and calcium sulfates (CS) are commonly used as tile adhesives, self-levelling compounds, repair cements or technical mortars. Different setting and hardening times as well as expansion, shrinkage and early strength can be easily controlled by varying the proportions of the three components. Many studies have...

46. Controlled calcium sulfoaluminate synthesis and influence of superplasticizers on the formation kinetics

CAC as an Accelerator for OPC (or other cements)

Oral Presentation

Ettringite (AFt) is a key phase influencing the early-stage hydration and rheology of calcium aluminate, calcium sulfoaluminate and blended cements. However, a quantitative and mechanistic understanding of early-stage hydration - specifically nucleation and growth- remains unclear, which is fundamental for optimizing the material performance.

In this study, we have developed the synthesis...

43. Identifying Premature Deterioration Using Volatilomics

Prof. Jason Ideker (Oregon State University), Oluwaseun Jegede (Oregon State University)

CAC as an Accelerator for OPC (or other cements)

Poster Presentation

This research pivots to the field of volatilomics for disease detection to develop new quantitative tools for diagnosing deterioration in the abiotic environment of concrete. Volatile organic compound metabolites, an oft-unused resource of chemical information produced by concrete-associated microbial communities, will be used to detect and characterize concrete deterioration. Scanning...
