Apstrakt

Dobijen je set eksperimentalno-statističkih modela koji omogućavaju predviđanje obradivosti i čvrstoće betona na kompozitnom vezivu, uključujući dodavanje prašine iz peći cementnog klinkera i granulisane šljake visoke peći, kao i polikarboksilatnog superplastifikatora Sika VC. 225. Određene su vrednosti kritičnog vodocementnog odnosa koje određuju oblast konstantne potražnje za vodom i uzimaju u obzir normalnu konzistenciju veziva, kao i koeficijente adsorpcije finih i krupnih agregata. Dobijeni su eksperimentalno-statistički modeli koeficijenata koji određuju prinos čvrstoće betona po 1 kg kompozitnog cementa i portland cementa Cem I koji se u njemu nalazi.
