Mikro-porozna struktura betona od troske visokih radnih karakteristika (SHPC - Slag High Performance Concrete) od velikog je utjecaja na njegovu provodljivost i izdržljivost. Na temelju eksperimenta provodljivosti zraka i eksperimenta s ubrizgavanjem žive, autor analizira korelaciju između strukture pora SHPC i provodljivosti zraka, uzimajući parametre provodljivosti zraka i strukture pora SHPC kao slučajne varijable, tražeći mehanizam i stupanj utjecaja različitih omjera miješanja parametara strukture pora SHPC na provodljivost zraka. Istraživanje i analiza pokazuju da su promjer središnje pore i promjer praga SHPC svakako povezani s provodljivosti zraka i mogu se koristiti za predstavljanje zračne provodljivosti SHPC, dok ostali parametri nisu s njom usko povezani i ne mogu je pojedinačno predstavljati.

The micro-porous structure of slag high performance concrete (SHPC) imposes great influence on its permeability and durability. Based on air permeability experiment and mercury injection experiment, the author analyses the correlation between SHPC pore structure and air permeability by taking parameters of SHPC air permeability and pore structure as random variables, finding the mechanism and level of influence of various mix proportions of SHPC pore structure parameters on air permeability. Research and analysis show that median pore diameter and threshold diameter of SHPC are certainly correlated to air permeability and can be used to represent SHPC air permeability, while other parameters are not closely correlated to it and cannot represent SHPC air permeability directly by single one.
