The invention relates to the field of building materials, in particular to a novel building engineering material. The novel constructional engineering material is prepared from the following raw materials in parts by weight: 50-80 parts of Portland cement, 5-8 parts of silica fume, 2.5-4 parts of recycled aggregate, 6-8 parts of nano silicon dioxide, 7-15 parts of linear low-density polyethylene fiber bead strings, 1-2 parts of lauryl sodium sulfate, 0.5-1.5 parts of polyol, 1-3 parts of sodium lignin sulfonate, 0.2-0.8 part of a defoaming agent, 0.2-1 part of an anti-settling agent,1-2 partsof dispersant, and 30-40 parts of water. According to the novel constructional engineering material of the invention, a fiber bead chain reinforcing mode is adopted, a structural constraint replaces aprevious interface constraint, so that the mechanical property and the crack resistance of concrete are greatly improved; a large amount of carboxyl and hydroxyl are formed after the nano silicon dioxide and the polyhydric alcohol meet water, so that the slump and the expansion degree of the concrete can be remarkably reduced, and the strength of the material is improved to the greatest extent.
本发明涉及建筑材料领域，具体涉及一种新型建筑工程材料，由以下重量份的原料制备而成：硅酸盐水泥50～80份、硅灰5～8份、再生骨料2.5～4份、纳米二氧化硅6～8份、线性低密度聚乙烯纤维珠串7～15份、十二烷基硫酸钠1～2份、多元醇0.5～1.5份、木质素磺酸钠1～3份、消泡剂0.2～0.8份、防沉剂0.2～1份、分散剂1～2份、水30～40份。本发明采用纤维珠链增强方式，用结构约束取代了以往的界面约束，大大提高了混凝土力学性能和抗裂性能；协同纳米二氧化硅和多元醇遇水后形成的大量的羧基和羟基，能够显著降低混凝土的坍落度与扩展度，最大限度提高材料的强度。
