The Northern regions of Eurasia and North America are affected by low and very low temperatures in winter. But, despite it, active mastering of these territories, and, therefore, and creation of construction objects from reinforced concrete is conducted. On reinforced concrete structures, depending on their location, there are different types of loads. Impact loads are divided into mechanical loads, such as vehicle weight (for road plates) and internal loads (from freezing water in capillaries). For each of these loads pick up the methods of counteraction, beginning from actions at the stage of production of cement, special technological actions at the stage of laying and care of concrete, and pumping by surface treatment of a ready design or product. Only with the right selection of each component and the choice of the most suitable technology, it turns out to achieve the desired frost resistance of the reinforced concrete product. |
