Proportioning of various kinds of concrete and accordance of their properties to norms of Russian Federal Standard is one of the important technological tasks. Realization of these tasks is connected with some problems. Concrete mix influences on its durability on the level of operating reliability bearing strength as well as on the level of use of resources which are required for manufacture of construction and prefabricated elements. Generally, proportioning of various kinds of concrete is connected with decision of some important tasks:
1. Choice of water-cement ratio influencing on durability of concrete structure (part) and corresponding to work conditions of construction. Durability is usually considered as concrete compressive strength that influences on many other properties of concrete.
2. Production of necessary concrete consistence influencing on mobility and placeability of concrete and required concrete quality. The right combination of concrete components is selected to reach this purpose.
3. The lowest costs of means on production of concrete and its laying.
Now there are rather a large number of the methods actual development of which is the following: 1) more complete accounting of factors and design requirements for concrete; 2) increase in efficiency of calculation algorithm. In solving problems concerning heavy concrete it is necessary to define values of the water-cement ratio and water consumption taking into account demanded mobility or rigidity of concrete mix, and consumption of aggregates. Taking into account the development of computer technologies there is a need of automation of the solution of the tasks of this type that is the selection of heavy concrete composition based on their functions and working conditions.
We can conclude that it is necessary to improve the algorithms of calculation of concrete composition and their automation to increase productivity and to facilitate the solution of this problem at the enterprises.
