Ten wall formworks (2 Scots pine, 2 Black poplar, 1 stell iron and 5 plywood) with different surface properties were constructed in this study. Three out of five plywoods were prepared with holes and canals and these prepared formworks were covered with different types of geotextile liners. The concrete was casted into all formworks under the same conditions. The prepared concrete walls were kept under atmospheric conditions for six years in horizontal position. Every year, the surface hardness of the concrete walls were determined with a Schmidt hammer. The findings were evaluated regarding the climate conditions. The findings of this study indicated that the concrete blocks containing geotextile liners were less affected from climate conditions. In addition, formworks with liner gave better surface hardness compared to the others.trinfo:eu-repo/semantics/closedAccessConcreteformworksurface hardnessdrainagelinerArticle234885894N/A
