The invention relates to self-leveling concrete for laying a building floor heating pipeline and a preparation method of the self-leveling concrete, and belongs to the technical field of concrete for buildings. The self-leveling concrete for laying the building floor heating pipeline is prepared from the following components in parts by weight: 120 to 150 parts of cement, 80 to 100 parts of slag powder, 300 to 350 parts of sand, 150 to 200 parts of stone, 3 to 5 parts of silica sol, 1 to 1.5 parts of polyoxypropylene glycerol ether, 2 to 5 parts of water reducing agent, 15 to 20 parts of modified microcrystalline cellulose, 20 to 30 parts of expanded perlite and 150 to 180 parts of water. The prepared concrete is good in fluidity, capable of achieving self-leveling, good in durability and strength, capable of being applied to backfilling of various building floors and heat preservation layers and laying of building floor heating pipelines, and long in service life. 本发明涉及一种建筑地暖管线铺设用自流平混凝土及其制备方法，属于建筑用混凝土技术领域。本发
