Types of thermal treatment chambers
Analyzing the types of heat -laying chambers, you should shortly dwell on the issues of accelerating the hardening of products, since this process, being the longest in time, is the main obstacle to the intensification of factory production in general. At the same time, there are real methods of accelerating the processes of thermal processing in practice. They are in use:
Particularly rapidly solid cements in which the turnover of molding equipment increases, which allows increasing production of 20-25 %on the same production areas;
Heated concrete mixtures (electro- and steam-heating), in which the duration of the heat treatment of products and 10-12% cement consumption is reduced by 30-50%. If you want to build a house, it is better to order its construction to professionals here – wooden houses are inexpensive.
concrete hardening accelerators providing production of production by 10-15%.
In the practice of domestic full-term housing in accordance with regulatory requirements and conditions for the manufacture of structures, the period of thermal processing of products at a heating temperature of 85-98 ° C lasts about 12 hours, which is 70-80% of the duration of the total technological cycle.
At the same time, at a number of France, Denmark and other foreign countries, the duration of thermal processing of structures is 3-5 hours at a heating temperature of 60 ° C. Such heat treatment periods are explained by the use of highly active cements of the type of produced in our country of particularly rapidly solids, allowing you to get 50-55% of the design strength under these modes.
