In addition, limestone powder, as an inert material, didn’t participate in the early cement hydration basically[3], and it had much more fine particles which could fill the gap between cement clinker and fly ash particles to reduce the water of the gap, so the water requirement decreased.

Materials and Methods During the operation, dimensional relations do not remain constant [1, 2, 3].
Internal factors are parameters that determine the operational properties of the mating surfaces: material of parts, lubricants, quality parameters of the surface layer etc.
The generative approach to the technology development involves the automatic synthesis of treatment strategies based on geometric configuration and technical requirements for parts, with information about the material, processing specifics and proposed control methods of the product.

Introduction Grain seeds: wheat, barley, oats, rice, maize, buckwheat, etc. which provide food for humans and animals, as well as the raw material of some industrial enterprises, have an average moisture content of freshly harvested grains ranging from 13% to 40%.
In order to remove the water from the drying process, drained through the tubes (48) and (44), a container is used made of a silica gel-type hygroscopic material (46) supported by a sheet metal base (45) fixed on a pair bracket-embedded blade transducers (47), (41) on which resistive tensometric resistors (42), (43) are placed bound in the semi-bridge and coupled to the tensometric bridge (24).
By using the automation, measuring and control devices of the process parameters with which the grain seeds and technical plant drying unit was equipped, very close or even identical values of the humidity and the drying temperature of some samples of wheat, maize and sunflower were obtained, which leads to the idea that such systems, redesigned and adapted to the requirements of industrial installations, can lead to corresponding energy consumption results, end-stage parameter values of the materials to be dried, and to the design of some machines with the possibility to adjust the highly flexible technological parameters.
