Modern concretes based on the Rapid-Hardening Portland cement compositions / Taras Mazurak, Iryna Kirakevych // Геодезія, архітектура та будівництво : матеріали V Міжнародної конференції молодих вчених GAC-2013, 21–23 листопада 2013 р., Україна, Львів / Національний університет "Львівська політехніка". – Львів : Видавництво Львівської політехніки, 2013. – С. 88–89. – (4-й Міжнародний молодіжний фестиваль науки "Litteris et Artibus"). – Bibliography: 8 titles.https://ena.lpnu.ua/handle/ntb/26920In the paper results of testing of building and technical properties of High Performance Concretes (HPC) based on the Rapid-Hardening Portland cement compositions with complex chemical admixtures are shown. It was observed, that strength of developed concretes after 2; 7 and 28 days of hardening is respectively 54.4; 60.1 and 80.9 MPa, what gives the reason to determine these materials to Rapid-Hardening and High Strength Concretes. The modern concretes based on the Rapid-Hardening Portland cement compositions are characterized by better construction and technical properties, which provide durability of constructions in different conditions.enComplex chemical admixturesRapid-Hardening Portland cement compositionsHigh Performance Сoncrete (HPC)Self-Compacting Concrete (SCC)building and technical propertiesModern concretes based on the Rapid-Hardening Portland cement compositionsArticle
