High strength light-weight concrete and preparation method thereof

The invention discloses high strength light-weight concrete, the concrete is prepared from the following components in parts by weight: 40 to 60 parts of cement, 20 to 40 parts of ceramsite, 20 to 30parts of coal ash, 10 to 20 parts of fine sand, 5 to 15 parts of calcium carbonate, 15 to 25 parts of light calcined magnesia, 2 to 8 parts of polypropylene fiber, 5 to 15 parts of microsilica fume, 3to 8 parts of calcium monofluorophosphate, 5 to 15 parts of nano silicon dioxide, 8 to 15 parts of desulphurization gypsum, 5 to 10 parts of quartz sand, 2 to 7 parts of expanded vermiculite, 4 to 10parts of sodium dodecyl sulfate, 2 to 8 parts functional agent and 80 to 100 parts of deionized water. The high strength light-weight concrete provided by the invention has the characteristics of light weight, high strength, good weather resistance, good heat-insulating property and the like, can meet index requirements of construction industry to ceramsite concrete performance and has better application prospect. 本发明公开了种高
