20.500.12556/DKUM-74765 Določitev optimalne mešanice betona z uporabo PP mlevcev kot nadomestilo mineralnega agregata Choosing the Optimal Concrete Mixture by Using PP Mills as a Substitute for Mineral Aggregate V projektni nalogi smo določali optimalno betonsko mešanico, pri kateri bi delež agregata zamenjali s polipropilenskimi (PP) mlevci. Nadomestili smo 1,5 %, 2 % in 5 % mase agregata 0/4, ter zamešali še etalon za primerjavo. Nadomestili smo tudi 30 % mase cementa z elektrofiltrskim pepelom. Želeli smo pridobiti beton z izboljšanimi lastnostmi. Ugotovili smo, da je betonu mogoče povečati tlačno in ohraniti upogibno natezno trdnost. Plastics are one of the biggest environmental pollutants, and concrete is (right after water) the most massively used material [2]. In the project work we were choosing the optimal concrete mix, at witch we would substitute a share of aggregate with polypropylene (PP) mills. We substituted 1,5 %, 2 % and 5 % of mass of aggregate 0/4, and mixed an etalon for comparison. We also substituted 30 % mass of cement with fly ash. We wanted to make concrete with improved characteristics. We found that the concrete`s compressive strength can be improved without lowering its tensile strength, and that the most suitable of the samples we made is the one that contains 2 % of substitute. gradbeništvo beton polipropilen PP plastika civil engineering concrete polypropylene PP plastics true true false [U.
