Tkachenko G. Complex activation of the microstructure of concrete as open complex systems

Object of researches - concrete and reinforce-concrete elements, constructions from cement-ash ceramsite concrete on carbonate sand, including preliminary tense; a purpose - to prove experimentally the possibility of the use of cement-ash ceramsite concrete on carbonate sand in the bent reinforce-concrete elements and constructions, including preliminary tense; methods - an analysis of the literary sources (for work's purpose' and tasks' formulation), the experimental researches, calculable methods of the statistical processing of experimental data with the use of the system "Compex-99" software, the comparative analysis of experimental information to the results of calculation; results - the expedience of the use of wastes of ash from the power station in composition of easy construction concretes and bearings constructions on their basis is founded out; the reliable statistical dependences which allow to forecast strength and deformation properties of ceramsite concrete on cement-ash and their changes in time are got; the values of durability, deformation and fracture strength for the estimation of bearing strength and service ability of reinforce-concrete beam constructions and prestressed floor slabs from cement-ash ceramsite concrete are got; novelty - possibility of utilization of wastes of industry is first grounded, namely wastes of ash from the power station in construction easy concretes; new regularities of composition factors' influence on descriptions of durability and deformation of ceramsite concrete on carbonate sand and cement-ash astringent at the action of the brief and protracted loading are established; new information on determination of tripping descriptions of ceramsite concrete on carbonate sand and ceramist-ash astringent with the use of unstressed armature with periodic type is got; new experimental information of durability, deformations and fracture strength of the bent elements with the use of ceramsite concrete on carbonate sand and cement-ash astringent at the action of the brief and protracted loading is got; the recommendations to their use in calculations are given; it is inculcated - at building of dwelling-house, at planning of dwellings objects, at making of constructions, in an educational process.
