The paper presents the composition and properties of low-emission ternary cements: Portland multicomponent cement CEM II/C-M and multicomponent cement CEM VI. In the ternary cements, Portland clinker was replaced at the levels of 40% and 55% with a mixture of the main components such as limestone (LL), granulated blast furnace slag (S) and siliceous fly ash (V). Portland multicomponent cements CEM II/C-M and CEM VI are low-emission binders with CO emissions ranging from 340 (CEM VI) kg to 453 (CEM II/C-M) kg per Mg of cement. The results obtained indicate the possibility of a wider use of ground limestone (LL) in cement composition. This is important in the case of limited market availability of fly ash and granulated blast furnace slag. The tests conducted on concrete have shown that the necessary condition for obtaining a high strength class and durability of concrete from CEM II/C-M and CEM VI ternary cements is low water-cement ratio. Durability characteristics of concrete (carbonation susceptibility, chloride ion permeation, frost resistance) made of CEM II/C-M and CEM VI cements were determined after 90 days of hardening. This period of curing reflects the performance properties of the concrete in a more effective way.
波特兰多组分水泥CEM II/C-M和多组分水泥CEM VI。在三元水泥中，波特兰熟料分别被40%和55%的主要成分混合物替代，这些主要成分包括石灰石（LL）、粒化高炉矿渣（S）和硅质粉煤灰（V）。波特兰多组分水泥CEM II/C-M和CEM VI是低排放胶凝材料，每毫克水泥的CO排放量在340（CEM VI）千克至453（CEM II/C-M）千克之间。所得结果表明在水泥组成中更广泛使用磨细石灰石（LL）的可能性。在粉煤灰和粒化高炉矿渣市场供应有限的情况下，这一点很重要。对混凝土进行的测试表明，使用CEM II/C-M和CEM VI三元水泥获得高强度等级和耐久性混凝土的必要条件是低水灰比。由CEM II/C-M和CEM VI水泥制成的混凝土的耐久性特性（碳化敏感性、氯离子渗透性、抗冻性）在硬化90天后测定。这段养护期能更有效地反映混凝土的性能特性。
