In this study, simple laboratory instruments were used, i.e., a mini-slump for spreading out diameters and a Marsh cone for flow-times measurements. A wide variation of combinations was used as preliminary tests to select pastes with acceptable properties and the use of the mixture-plans method has shown that it is possible to define an experimental field inside which optimal measurements can be obtained. This field has been put mathematically into equation form, conditioned by implicit constraints, defining zones of minimal shearing threshold and maximum viscosity and was then solved numerically. The optimization criterion was checked in addition to the interactivity between the components utilizing the multiple combinations of proportioning these materials. From the results given by the ternary diagrams and desirability functions, an optimal self-compacting cement-paste mixture was defined. Experimental checking was performed to validate the obtained results"},{"@xml:lang":"sl","#text":"V članku je prikazan razvoj samozgoščujoče cementne malte z uporabo lokalnih alžirskih materialov (binarni cement iz naravnega vulkanskega pepela pozzolane in apnenca kot polnila). V raziskavi so uporabljene enostavne laboratorijske priprave: mini stožec in Marshev stožec za meritev časa iztekanja. Širok razpon variacij je bil uporabljen pri predhodnih preizkusih za izbiro malt s sprejemljivimi lastnostmi. Uporaba metode mešalnih načrtov je pokazala, da je mogoče eksperimentalno opredeliti polje, v katerem je mogoče dobiti optimalne meritve. To polje je bilo formulirano z matematičnimi enačbami, odvisnimi od implicitnih omejitev, ki opredeljujejo cone minimalnih strižnih pragov in maksimalne viskoznosti in je bilo nato rešeno matematično. Merilo optimizacije je bilo preverjeno kot dodatek k interaktivnosti komponent z uporabo multiplih kombinacij proporcioniranja materialov. Iz rezultatov v ternarnih diagramih želelnih funkcij je bila definirana optimalna samozgoščujoča cementna zmes.
