▎ 摘 要
NOVELTY - A structural concrete block (10) is of the type comprising a parallelepipedic component with two transverse holes (11) passing and parallel to each other, comprises 1 %mass cement, 0.5-4.0 %mass, preferably 1.9 %mass sand as a small aggregate, 0.9-3.0 %mass, preferably 2.0 %mass gravel as a large aggregate, 0.0-2.5 %mass, preferably 1.1 %mass stone powder, and 0.015-0.08 %mass, preferably 0.021-0.04175 %mass graphene oxide with respect to the total content of cement. USE - Structural concrete block used for buildings. ADVANTAGE - The structural concrete block has excellent resistance to compression and excellent reduction in the absorption of water. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of the structural concrete block. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the structural concrete block. 10Structural concrete block 11Transverse holes
