Analysis of selected properties of fresh mix and hardened self-compacting concrete

Analysis of samples and series of properties of the fresh mix – consistency and viscosity – and hardened concrete – compressive strength and abrasion resistance of self-compacting concrete. The data were obtained through physical testing. A caliper was used to measure all dimensions. The consistency and viscosity tests were carried out on a flow table for concrete using the Abrams cone.All variables marked in mm indicate dimensions in a given direction. For the compressive strength test, the dimension of side A was measured on both sides, the dimension of side B was measured on both sides of the cubic specimen, as well as the height H. Compressive strength was calculated using the formula force / area.For abrasion resistance, the Böhme disc apparatus was used, in which the loss of mass and specimen height was measured over 16 cycles. The height h was measured before the test, h 4c after 4 test cycles, and h 16c after 16 cycles.
