Space model and strength of a hardened concrete sample

Opisan je prostorni model uzorka očvrslog betona polazeći od poznate teorije, eksperimentalnih podataka i prostornog modela uzorka svježeg betona. Izračunavaju se vrijednosti parametara pri normalnoj i nepotpunoj hidrataciji cementa. Na temelju rezultata ispitivanja betona različitih sastava, definiraju se dva područja različitog ponašanja uzoraka. Za svako područje izvodi se empirijska formula koja određuje vezu parametara prostornih modela uzoraka i tlačna čvrstoća.The space model of a hardened concrete sample is described based on the known theory, experimental data and space model of the fresh concrete sample. Values of parameters at normal and incomplete hydration of cement are calculated. Two areas of different sample behavior are defined according to results obtained by testing concrete types of different composition. An empirical formula defining relationship between parameters of space models of samples and compression strength, is derived for each area
