Experimental factors

Conditions

OCA

Cutting specimen of crushed hard sandstone

(Standard density: 2.66 g/cm³, Water absorption ratio: 0.70%)

SMCP

W/C

30%

Modification materials

Cement, Fly ash (F/A), Blast furnace slag (BFS), Silica fume (S/F)

Replace ratio of modification materials (%)

Cement = 100 Cement + Fly-ash (F/A) = 70:30 Cement + Blast Furnace Slag (BFS) = 70:30 Cement + Silica-fume (S/F) = 90:10

Cement matrix

Normal strength W/C = 55%

Interface angle

30˚, 45˚, 60˚
