Abstract

The invention discloses an ultra-high performance concrete stone-like brick, and relates to the technical field of building materials, wherein the ultra-high performance concrete stone-like brick comprises a surface layer and a bottom layer; an interlayer is arranged between the surface layer and the bottom layer; the surface layer comprises the raw materials in parts by weight: 750-850 parts of PW cement, 120-140 parts of heavy calcium carbonate powder, 120-140 parts of white silica fume, 10-40 parts of titanium dioxide, 1100-1250 parts of quartz sand, 10-20 parts of high strength fiber, and 100-140 parts of water; the bottom layer comprises the raw materials in parts by weight: 700-750 parts of PO cement, 110-125 parts of fly ash, 180-210 parts of silica fume, 1150-1250 parts of quartz sand, 90-110 parts of high-strength fiber and 120-150 parts of water. The brick has the advantages of attractive appearance and high fracture resistance and tensile strength, can be directly used for ground pavement, and can improve the safety of buildings.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an ultra-high performance concrete imitation stone brick. Background technique [0002] Concrete bricks are solid bricks made of cement, aggregate, admixtures, additives and other raw materials, mixed with water, shaped and cured. They have the characteristics of high compressive strength and are mainly used for masonry walls or ground pavement. [0003] The compressive strength of concrete bricks is much greater than its tensile strength and flexural strength, which is very suitable for the construction of high-rise buildings or paved roads. However, due to the low flexural strength, concrete bricks are easy to break when the force is uneven, making concrete brick The scope of application of concrete bricks is very limited, especially when used as pavement bricks, concrete bricks are often broken or crushed, and the appearance of concrete bricks is mostly light gray t...
