N2 - Flowable low-pH concrete was developed and demonstrated for closure of site investigation boreholes. The boreholes have been used during geological characterization of the nuclear spent fuel disposal site at Olkiluoto, Finland. Posiva Oy has over 60 deep cored boreholes of varying diameter (typically 56 to 76 mm) and at lengths from 200 to 1200 metres deep. Two holes were sealed in 2016 using materials developed in VTT's laboratories. The low-pH concrete needed to have high workability for casting emplacement to a 1000 metre deep hole and high long-term durability with low hydraulic conductivity. The results are being used for license applications to Radiation and Nuclear Safety Authority of Finland, to show compliance with repository safety.
