Negative carbon recycled aggregate concrete and preparation method of prefabricated component of negative carbon recycled aggregate concrete
The invention discloses a negative carbon recycled aggregate concrete material which is prepared from the following raw materials in parts by mass: 300-500 parts of negative carbon recycled coarse aggregate; 500 to 700 parts of natural coarse aggregate; 216 to 360 parts of negative carbon recycled fine aggregate; 360 to 504 parts of natural fine aggregate; 200 to 250 parts of a mineral admixture; 350 to 400 parts of cement; 8 to 12 parts of a water reducing agent; 150 to 210 parts of water; the mineral admixture is prepared by mixing slag, fly ash and steel slag according to the mass ratio of 1: (1-2): (1-1.2) and then adding a small amount of nano silicon dioxide. According to the invention, the compactness of the recycled aggregate is increased, so that the physical and mechanical properties of the recycled concrete are improved, the resource reutilization of the building waste solid material can be realized, the mechanical properties of the concrete are ensured by the proportion of 30-50% of the negative carbon recycled aggregate in the concrete proportion, and the natural aggregate resource is saved.
本发明公开了一种负碳再生骨料混凝土材料，由包含以下质量份数的原料制备而成：负碳再生粗骨料：300～500份；天然粗骨料：500～700份；负碳再生细骨料：216～360份；天然细骨料：360～504份；矿物掺合料：200～250份；水泥：350～400份；减水剂：8～12份；水：150～210份；所述矿物掺合料为矿渣、粉煤灰、钢渣按照质量比1：1～2：1～1.2混合，然后再加入少量纳米二氧化硅制得。本发明使得再生骨料密实度增大提高，从而提高再生混凝土的物理力学性能，可实现建筑废弃固料的资源再利用，混凝土配比中30％～50％的负碳再生骨料占比保障了混凝土的力学性能，节约了天然骨料资源。
