Modelling freeze-thaw durability of high-performance concretes
Contours of estimated response surfaces for surface scaling and internal damage of slab and CIF/CDF freeze-thaw test results of 42 test concretes were produced statistically. Water uptake of the test concretes in the slab tests was the most dominant variable affecting the surface scaling and internal damage caused by freezing and thawing loads when pure water and salt solution was the freezing liquid. The obtained R-squared values of the models of the slab test results ranged from 80.8 to 96.8 %. Also in the internal damage deterioration of the CIF/CDF tests water uptake was the most dominant variable in the freeze-thaw phenomenon. However, in the CIF/CDF tests the surface scaling damage could be modelled with higher accuracy by using pore volume and water-binder ratio data. The R-squared values in the CIF/CDF test models ranged from 77.3 to 98.6 %.
