Abstract
A method for the refurbishment of porous construction materials and a composition including Portland cement, calcined clay, and optionally aggregate to be used in the method for the refurbishment of porous construction materials. The method includes the steps of mixing water and a composition C, the composition C including, a) 100 mass parts of Portland Cement, b) 1-18 mass parts, preferably 1-10 mass parts, more preferably 1-7.5 mass parts, still more preferably 1-6 mass parts, especially 1-5 mass parts of calcined clay, c) optionally 10-250 mass parts of aggregates, applying the mixture thus obtained to a porous construction material, and optionally hardening the applied mixture.

A method for a refurbishment of porous construction materials, the method comprising:
- mixing water and a composition C to form a mixture, the composition C comprising:
- a) 100 mass parts of Portland Cement,
- b) 1-6 mass parts of calcined clay, and
- c) optionally 10-250 mass parts of aggregates,
- applying the mixture thus obtained to a porous construction material, and
- optionally hardening the applied mixture,
- wherein the Portland cement is a high early-strength Portland Cement with a Blaine surface as measured according to EN 196-6:2010 of 2,500-10,000 cm2/g.
