therefore, polished concrete with the addition of hardeners improves the cement mpa by 3 - 4 time times to 75 – 100 mpa. the result is a much harder floor surface than standard concrete. exposed: aggregate within the concrete mix that is revealed during the concrete grinding for polishing
they can either be ground flat to fully expose the aggregate like terrazzo, or the aggregate can be partially exposed, or the concrete grinding can expose no more than the fine sands at the surface. it often takes skill and experience to control the process of polished concrete floors and the quality of the concreter’s original laying work is also a contributing factor in the quality of the
