Basic characteristics of hardened concretes.

	0/1	0/2	0/3	1/1	1/2	1/3
Bulk density [kg/m^3]	2310; (11.0)	2320; (8.62)	2330; (18.5)	2320; (8.08)	2330; (4.04)	2360; (1.73)
Compressive strength [N/mm^2]	33.3; (0.19)	44.5; (0.49)	55.8; (2.23)	42.8; (0.84)	50.8; (0.22)	56.4; (2.21)
Dynamic modulus of elasticity [N/mm^2]	29000; (503)	34600; (661)	35000; (281)	30600; (563)	31200; (670)	32900; (671)

Note. All materials’ characteristics are represented by mean values and (standard deviation) both introduced in the same units. Values of dynamic modulus of elasticity were determined using the resonance method according to [32].
