Abstract

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.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high-strength lightweight concrete and a preparation method thereof. Background technique [0002] High-strength ceramsite concrete is a kind of light aggregate concrete. The strength range currently used is LC5.0-LC60. Due to its high strength, light bulk density, not easy to crack due to temperature difference, small self-shrinkage, good freeze-thaw resistance, after forming concrete Being able to form self-maintenance and other characteristics, it is one of the main energy-saving and environmental protection materials that are currently being promoted in the new century. Ceramsite concrete began to develop in my country in the 1960s, mainly used for thermal insulation materials and non-load-bearing structures. In the late 1990s, with the rapid development of foreign technology, it also gradually developed rapidly and has C50 grade high-strength ceramsite concrete....
