Abstract
The pressed products technology allows to automate production, to manufacture construction elements for finishing and grinding with precise dimensions, high strength, plain surface. But there are many unsolved problems in pressed products technology. The main of them are connected with the dependence of pressing pressure on concrete mix compaction level and its properties. The article deals with the mathematical description of pressed concrete mix properties when using concrete mix structural characteristics. The possibility was found to forecast pressed concrete mix needful pressure weight, density of product or relative deformation.

Summary
Siame darbe buvo siekiama gauti priklausomyb~ tarp presavirno slegio ir betono misinio santykinio tankio, ivertinant apibendrintas betono misinio struktiiros charakteristikas. 3. Presuojamo betono misinio savybill fVertinimo principai leskant funkcines priklausomybes tarp santykinio betono misinio tankio ir presavimo slegio, pastebeta, kad geriausiai j~ apibiidina logaritmine funkcija (1 pav.). IS (5) statistines priklausomybes matyti, kad koeficientas a apibudina presuojamo betono misinio tankio kitimo kinetik&. Pagal gautas matematines israiskas (5), (9) ir (10) apskaiciavus skaiciuojamll_sias santykinio betono misinio tankio reikSmes ir paklaidlt tarp skaiciuojamlijq ir bandymq metu gautq rezultatq (gauta vidutine santykine paklaida lygi 4,79%), galime teigti, kad siq formuliq patikimumas yra pakankamas. Apskaiciavus supresuoto betono misinio santykinio tankio reiksmtt ir gavus daugiau kaip vienet!t, galima tiketis, kad is betono misinio bus isspaustas vanduo, kartu keisis tiirines betono komponentq koncentracijos ir savitasis betono misinio tankis. Ps.b.o. - piltinis betono rnisinio tankis, apskaiciuojamas esant nuliniam presavimo slegiui pagal (5), (9), (10) fonnules
