Research of hydration heat of Portland cement used in bridge construction of Kerch Strait

摘要

The article discusses issues related to the study of heat generation of cements used in the construction of a bridge across the Kerch Strait. This problem seems to be important because of the construction of the mentioned object in conditions of a dry hot climate. The study was conducted with the use of modern information and analytical systems in real time, allowing obtaining results close to real conditions. On the basis of comparative analysis of the calculation and practical measurement of heat the main conclusions of the work were done, recommendations on the use of cements of various types in the construction of the bridge Kerch and other similar extra-curricular facilities that are included in the basis of the developed technological regulations for the production of preparatory, reinforcement, formwork and concrete works in circumstance of year-round construction.
