La resistencia a las heladas es una de las características más importantes que describen un elemento estructural de hormigón. En condiciones de procesos de congelación/descongelación frecuentes y repetidos, la estructura se debilita significativamente. Lo... see more

Frost resistance is one of the key indicators of concrete quality. Frost resistance can be determined by direct testing; however it is time-consuming and labour-intensive method. Concrete decomposition is a complex process (from initial signs of degradati... see more

 
The paper discusses the basic stages of modeling the processes of ice formation concrete. The conditions for the formation of ice in the pore space of concrete. The technique of determining ice formation, based on the finite element method, differential s... see more

Over time, the pavement structure deteriorates. Factors that contribute to the deterioration of the pavement structure are traffic load, material properties and climate influences. Low temperatures lead to freezing of water and the appearance of ice lense... see more

Frost stress is one of the most significant abiotic factors affecting chickpea (Cicer arietinum L.) production in the Ethiopian highlands. To investigate the frost tolerance of chickpea, 673 genotypes were characterized using an augmented design at Bakelo... see more

Investigation was performed in order to determine whether the predicted frost resistance of concrete in cycles, while using porosity parameters, corresponds to the number of cycles determined experimentally. The porosity parameters of concrete were determ... see more

Trees spring passing from the rest period to intense biological activity brings trees frost resistance decrease. In case of the apricot tree, specie with short biological rest period, return frosts are very harmful after the un-tempering period, but espec... see more

The aim of the study was: (i) to state if selected in the field conditions androgenic Festulolium genotypes are diverse in frost tolerance, and (ii) to investigate if changes in anitoxidant activity could be recognized as a physiological marker of this ty... see more
