The article analyzes the influence of the temperature of the medium on the speed of strength gain of concrete of workings support. For these purposes, comparative tests of concrete samples at the age of 0.5, 1.0 and 3 days were carried out. As a result of data processing, the dependences of the strength of concrete of support at an early age at different hardening temperatures were obtained. A method for predicting of concrete strength considering the temperature and parameters of thedoi:10.1051/matecconf/201926505033 fatcat:ehv65l7bsbdurge3ggga2xa2hq
