The experiments were conducted using a Design of Experiments approach to evaluate the combined effects of sodium silicate content, hardener content, and temperature on grout performance and environmental behavior. The dataset includes experimental design matrices and measured responses for gelation time, storage modulus after 4 h, syneresis, dissolution rate, and effluent pH. Raw time-sweep rheology data are provided separately for the three grout systems. The dataset also contains ICP-OES results for the temporal concentrations of dissolved elements, including sodium, silicon, and aluminum, in the leachates collected during the aging experiments. The data support the development and validation of regression models describing the formulation- and temperature-dependent behavior of sodium silicate grouts. They can be used to reproduce the analyses and figures reported in the associated study, compare the performance of different hardener systems, and support further research on grout formulation, injectability, mechanical development, aging, syneresis, chemical degradation, and potential environmental impacts."}}]},{"typeName":"subject","multiple":true,"typeClass":"controlledVocabulary","value":["Earth and Environmental Sciences","Engineering"]},{"typeName":"depositor","multiple":false,"typeClass":"primitive","value":"Valibeknejad, Mohammad"},{"typeName":"dateOfDeposit","multiple":false,"typeClass":"primitive","value":"2026-04-20"}]},"dansDataVaultMetadata":{"displayName":"Data Vault Metadata","name":"dansDataVaultMetadata","fields":[{"typeName":"dansDataversePid","multiple":false,"typeClass":"primitive","value":"doi:10.34894/VIURPF"},{"typeName":"dansDataversePidVersion","multiple":false,"typeClass":"primitive","value":"2.0"},{"typeName":"dansBagId","multiple":false,"typeClass":"primitive","value":"urn:uuid:887c82b3-c736-4733-b75a-fafb7e162b82"},{"typeName":"dansNbn","multiple":false,"typeClass":"primitive","value":"urn:nbn:nl:ui:13-a04d9082-4ae4-4791-a613-999d219b9b97"}]}},"files":[{"label":"03_ICP-OES_leachate_data.xlsx","restricted":false,"version":1,"datasetVersionId":35444,"dataFile":{"id":656476,"persistentId":"","filename":"03_ICP-OES_leachate_data.xlsx","contentType":"application/vnd.openxmlformats-officedocument.spreadsheetml.sheet","friendlyType":"MS Excel Spreadsheet","filesize":102134,"storageIdentifier":"surf://store:19f83cbaa58-53417351cb30","rootDataFileId":-1,"checksum":{"type":"SHA-1","value":"12053f2026d400e151ad4365e6ff19f8bb4320ac"},"tabularData":false,"creationDate":"2026-07-21","publicationDate":"2026-07-28","lastUpdateTime":"2026-10-02T12:37:13Z","fileAccessRequest":true}},{"label":"README.txt","restricted":false,"version":1,"datasetVersionId":35444,"dataFile":{"id":679952,"persistentId":"","filename":"README.txt","contentType":"text/plain","friendlyType":"Plain Text","filesize":6731,"storageIdentifier":"surf://store:1a0d3ea0bbb-49938704ee11","rootDataFileId":656475,"previousDataFileId":656475,"checksum":{"type":"SHA-1","value":"877297ee25ee3dc2bfa7c541a02743846f46f358"},"tabularData":false,"creationDate":"2026-09-24","publicationDate":"2026-10-02","lastUpdateTime":"2026-10-02T12:37:13Z","fileAccessRequest":true}},{"label":"Results.xlsx","restricted":false,"version":1,"datasetVersionId":35444,"dataFile":{"id":679926,"persistentId":"","filename":"Results.xlsx","contentType":"application/vnd.openxmlformats-officedocument.spreadsheetml.sheet","friendlyType":"MS Excel Spreadsheet","filesize":138219,"storageIdentifier":"surf://store:1a0d3cbcb33-a9649aebf47b","rootDataFileId":656473,"previousDataFileId":656473,"checksum":{"type":"SHA-1","value":"e60140fe683e88d51be8b36e12fa9fa2f99a42ae"},"tabularData":false,"creationDate":"2026-09-24","publicationDate":"2026-10-02","lastUpdateTime":"2026-10-02T12:37:13Z","fileAccessRequest":true}},{"label":"Rheology data.xlsx","restricted":false,"version":1,"datasetVersionId":35444,"dataFile":{"id":679927,"persistentId":"","filename":"Rheology data.xlsx","contentType":"application/vnd.openxmlformats-officedocument.spreadsheetml.sheet","friendlyType":"MS Excel Spreadsheet","filesize":32009974,"storageIdentifier":"surf://store:1a0d3ccb456-f37bd2c365d7","rootDataFileId":656474,"previousDataFileId":656474,"checksum":{"type":"SHA-1","value":"fc71020637dfa90c2adc7d74d38e4d3cd5d41219"},"tabularData":false,"creationDate":"2026-09-24","publicationDate":"2026-10-02","lastUpdateTime":"2026-10-02T12:37:13Z","fileAccessRequest":true}}]}}}
