Investigation, trial and use of CEM VI (C VI) concrete for a sustainable deep foundation future-PPT Presentation

PPT Presentation

Pdf Summary

The presentation describes the investigation, testing, site trials and implementation of a CEM VI concrete mix for deep foundations, as part of efforts to improve sustainability in construction.<br /><br />The mix was assessed for workability and stability, workability retention and durability. Compressive strength was also evaluated through suitability and identity testing, followed by site trials.<br /><br />Compared with a CEM IIIB mix, the CEM VI design used 100 kg/m³ less ground-granulated blast-furnace slag (GGBS) while incorporating up to 89 kg/m³ of limestone fines. The concrete achieved compressive strength significantly above the specified 40 MPa target, suggesting scope to further optimise the mix and reduce total cementitious material.<br /><br />The case study offers a basis for other industry practitioners to develop CEM VI mixes in accordance with BS 8500 Parts 1 and 2, published in 2023.
