Data from 'Oyster shell in limestone mortar', RAÄ-2025-1660
https://doi.org/10.5281/zenodo.20665656
This project (diarienummer RAÄ-2025-1660) focused on analyzing the properties of limestone mortar blended with oyster shell as a means to reduce the climate impact of limestone mortar production. Mortar samples were blended and shaped in molds, using different ratios of sand, limestone and oyster shell. After being removed from the molds the samples were allowed to cure in a room set to 65% RH and 20 degrees Celcius. Flexural strength and compressive strength were measured after 28 days and 90 days of curing. X-ray fluorescence analysis was performed directly on the samples to understand the chemical composition. SEM imaging was performed on samples of slaked oyster shells (both wet and dry) to observe the morphology. Instrument reports for all analysis methods are included, listing the sample names and descriptions. The data was collected as part of a bachelor's thesis at Uppsala University's Building Antiquanrian Program: https://urn.kb.se/resolve?urn=urn:nbn:se:uu:diva-597226.
