Self-compacting lightweight aggregate concrete and preparation method thereof
The invention discloses a self-compacting lightweight aggregate concrete, which is characterized by comprising 500 to 550 parts of cement, 250 to 350 parts of fly ash ceramsite, 50 to 150 parts of shale ceramsite, 150 to 250 parts of slag, 50 to 150 parts of clay ceramsite, 30 to 60 parts of silica fume, 200 to 250 parts of water, 10 to 15 parts of a water reducing agent, 1 to 5 parts of a defoaming agent and 10 to 15 parts of a thickening agent. Compared with the prior art, the self-compacting lightweight aggregate concrete disclosed by the invention has the advantages that a mode of mixing a large amount of lightweight aggregate of industrial waste residues with a small amount of artificial lightweight aggregate is adopted, so that the production cost of the self-compacting lightweight aggregate concrete is greatly reduced; in the production prcess, the lightweight aggregate of the industrial waste residues and the artificial lightweight aggregate are repeatedly mixed and then are mixed with the cement and the water, so that the influence of the lightweight aggregate of the industrial waste residues on the performance of the self-compacting lightweight aggregate concrete is reduced.
本发明公开了一种自密实轻骨料混凝土，其特征在于：它包括水泥500‑550份、粉煤灰陶粒250‑350份、页岩陶粒50‑150份、矿渣150‑250份、黏士陶粒50‑150份、硅灰30‑60份、水200‑250份、减水剂10‑15份、消泡剂1‑5份和增稠剂10‑15份。本发明与现有技术相比的优点在于：本发明采用大量的工业废渣的轻骨料配合少量人造轻骨料混合的方式，大大降低了自密实轻骨料混凝土在生产中的成本，同时在生产过程中，先将工业废渣的轻骨料和人造轻骨料混合进行重复混合后再配合水泥和水进行搅拌，减少了工业废渣的轻骨料对自密实轻骨料混凝土性能的影响。
