Lightweight environment-friendly concrete and preparation method thereof

Disclosed lightweight environment-friendly concrete comprises the following components: 120 to 140 kg/m of Portland cement, 30 to 45 kg/m of fly ash, 30 to 45 kg/m of mineral powder, 350 to 400 kg/m of sand, 655 to 702 kg/m of G5-20 mm pebbles, 518 to 545 kg/m of G20-40 mm pebbles, 5 to 15 kg/m of diatom mud microcapsules, 25 to 40 kg/m of ceramsite, and 100 to 130 kg/m of water. Diatomite, graphene oxide, activated carbon and other materials are microencapsulated to promote the concrete to form a porous structure, thereby facilitating contact between the capsules and outside air to implement the long-acting adsorption effect on indoor formaldehyde and other pollutants. The formed microcapsules can be matched with other components, so that the obtained concrete effectively has good light weight, high strength and stability, and is suitable for popularization and application. 本发明公开了一种轻质环保型混凝土，各组分及其含量包括：硅酸盐水泥120～140kg/m3，粉煤灰30～45kg/m3，矿粉30～45kg/m3，砂350～400kg/m3，G5-20mm卵石655～702kg/m3，G20-40mm卵石518～545kg/m3，硅藻泥微胶
