Construction process management is based on brief scheduling of the on-site performance of construction works. Therefore, it is frequently necessary to perform concrete works in wintertime when the air temperature is below 0C. Thus, the necessity of the assessment of low temperature conditions on the compressive strength of concrete should be assessed. The assessment of the concrete compressive strength is usually based on destructive tests of concrete specimen (cubes or cylinders in compliance with procedure stated in EN 12390). However, the free surface/volume ratio of the specimen as well as the environment where the specimen are stored has significant impact on the speed of the strength gain processes of the specimen. The impact of the specimen volume/surface area ratio and storage conditions of the specimen on their compresive strength results has been assessed in the paper.
