Freezing and thawing test on stone

WebThe test method is applicable to any natural dimension stone intended to be used in construction or landscape applications in areas where the material will be subjected to subfreezing temperatures. Test specimens are placed in a chamber that alternates between cooling and heating to produce freeze/thaw cycling. WebAverage values of FS 3 without freeze–thaw action and after 48 freezing–thawing cycles (FTFS 3) were calculated for 48 marbles (33 calcitic and 15 dolomitic), 43 limestones, 9 sandstones and 33 schists/slates. Since there is a direct connection between the two methods, as strength values are derived from both tests, it is possible to ...
