Abstract
The paper presents a study on the effects of different types of cement on selected properties of C30/37 road concrete. It involved three types of cement: Portland CEM I 42,5 R cement, Portland slag CEM II/B-S 32,5 R cement and CEM III/A 42,5 N LH/HSR/NA blast cement. The composition of the concrete mixtures were designed and evaluated experimentally. Test samples were prepared in laboratory conditions. The maturation period took 28 days for concrete with CEM I 42,5 R and CEM II/B-S 32,5 R, and 56 days for CEM III/A 42,5 N LH/HSR/NA cement. After maturation the samples were tested for: compressive strength, bending tensile strength and splitting tensile strength, water absorption and frost resistance. It was found that each of the concrete meets the requirements for road concrete listed in the GDDKiA technical specification [Ogólna Specyfikacja Techniczna... 2014]. In most of the tests the CEM III/A 42,5 N LH/HSR/NA cement performed best.
本文研究了不同类型水泥对C30/37道路混凝土选择性能的影响。它涉及三种类型的水泥:波特兰CEM I 42,5 R水泥，波特兰矿渣CEM II/B-S 32,5 R水泥和CEM III/A 42,5 N LH/HSR/NA爆破水泥。对混凝土配合比进行了设计和试验评价。试验样品在实验室条件下制备。CEM I 42,5 R和CEM II/B-S 32,5 R混凝土的成熟期为28 d, CEM III/A 42,5 N LH/HSR/NA水泥的成熟期为56 d。成熟后对试样进行抗压强度、弯曲抗拉强度、劈裂抗拉强度、吸水率、抗冻性等测试。经检测，各混凝土均符合GDDKiA技术规范[Ogólna Specyfikacja Techniczna…]2014]。在大多数测试中，CEM III/ a42,5 N LH/HSR/NA水泥表现最好。
