In order to determine the composition of heavy concrete intended for the construction of V-shaped bridge supports, there was used the TCVN 9382-2012 Vietnamese standard. The assessment of the possibility of cracking in monolithic concrete of the bridge support during its construction was performed by analyzing its temperature behavior and the resulting tensile stress. As a result of the study, it has been proved that it is possible to obtain heavy concrete with the required properties from local raw materials of Vietnam. With the help of the Midas Civil computer program, the maximum temperatures in the central zone of monolithic concrete construction were determined for all three phases of the construction of bridge support.
