Bulletproof explosion-proof brick of high-content gradation fiber recycled aggregate concrete and preparation method thereof

Abstract

The invention discloses a high-content grading fiber recycling aggregate concrete bulletproof explosion-proof brick, which is prepared from the following materials by mass: 16.30% of steel fibers, 0.04% of polypropylene fibers, 18.00-19.00% of cement, 5.40-5.60% of water, 2% of fly ash, 2% of slag powder, 2.60-3.00% of silica fume, 15.50-16.50% of sand, 36.00-37.00% of gravel, and 0.36% of an efficient water reducing agent. According to the present invention, the high-content grading fiber recycling aggregate concrete bulletproof explosion-proof brick has excellent compressive resistance, excellent tensile resistance, excellent bending resistance and excellent impact toughness compared to the clay bricks and the ordinary cement bricks, and is the novel high-performance composite material brick integrating high strength, bullet resistance, impact resistance, weight loading, bearing, wear resistance, and environment protection; and the purposes of resource saving and effective arable land and environment protection are achieved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a high-content graded fiber recovery aggregate concrete bulletproof and explosion-proof brick and a preparation method thereof. Background technique [0002] At present, my country is one of the few countries in the world that uses solid clay bricks as the main wall material. In my country, wall materials account for about 70% of the entire house building materials, of which clay bricks still play a dominant role in wall materials, and the clay resources required for the production of solid clay bricks are more high-quality clay in arable land, 5 million per year Mu of arable land was destroyed, of which 700,000 mu were destroyed. In order to save resources and effectively protect the cultivated land and the environment, many products that replace clay bricks have emerged, such as unfired bricks, cement bricks, and small concrete blocks. At present, the highest grade of sintere...
