Durability of MFS-Slag Concrete

By incorporation of MFS-slag in concrete mixtures at high cement and/or aggregate replacement levels, DUSC strives for:

(1) maximum residue valorisation and avoidance of waste disposal, and

(2) more durable and sustainable reinforced concrete structures, with a low carbon footprint, high service life and good recyclability.

MFS-slag based concrete (‘MFS-concrete’) is targeted which can be used as ready-mix concrete for structural applications, such as beams, columns and slabs of buildings and infrastructure.

The project deals with two different cement replacement levels. On the one hand, MFS-slag will be used as supplementary cementitious material to replace at least 25% of Ordinary Portland Cement (OPC). On the other hand, MFS-slag will be used at high (70%) OPC replacement levels by the additional use of an activator (or accelerator). These new concrete types are denoted ‘MFS-CS’ and ‘MFS-CA’, respectively.

MFS-CS is envisaged for short term commercialisation, while MFS-CA targets medium-to-long term commercialisation in view of continuously increasing market demands for eco-efficiency. In addition to the replacement of the cement, both types also apply coarse aggregate replacement.

This project is part of:

The MaRes Program is about recycling of ‘Materials from solid and liquid industrial process Residues’, and aims at creating and demonstrating an operational, flexible toolbox to recover metals and valorize residual matrix into building materials.
