Determination of conversion factors for compressive strength of HPFRC measured on specimens of different dimensions
Original language description
Current development of high-strength concretes is aimed at using high-strength aggregate with maximum grain size of four or eight millimetres. Ultra-high-strength concretes with compressive strength higher than 150 MPa are commonly produced in laboratories nowadays. For such concretes, measuring compressive strength on classic cubes with dimensions 150 mm x 150 mm x 150 mm is not suitable, as for this size of specimen the applied load of compression testing machine must be several thousand kiloNewtons.Reaching such values of applied testing load is difficult. Utilisation of smaller specimens for concretes with lower grain size is possible and strengths determined in tests with these specimens can be adequately accurate. The main objective of this paper is to present the research that investigated relations of compressive strengths measured on differently sized specimens. Results obtained for standard specimens (150 mm x 150 mm x 150 mm) are compared to 100 mm x 100 mm x 100 mm cubes.
