High content pozzolanic foamed concrete material and preparation method thereof

The invention relates to a high content pozzolanic foamed concrete material and a preparation method thereof. The high content pozzolanic foamed concrete material is prepared from the following raw materials in parts by mass: 30 parts of cement, 70 parts of pozzolanic ash, 0.1-1.0 part of a water reducing agent, 0.05-1.0 part of a foam stabilizing agent, 1.0-8.0 parts of early strength agents, 0.1-1.5 parts of organic fibers, 0.1-1.0 part of water repellent, 1.0-4.0 parts of foaming agents and 30-70 parts of water. The high content pozzolanic foamed concrete material has a dry apparent densityof 550-800kg/m , a compressive strength of 3-8MPa, a thermal conductivity of 0.10-0.18W/m.K, a content water absorption rate of 4-8%, has the characteristics of high strength, light weight, heat insulation, heat preservation, non combustion and the like, and can be used for preparing wall self insulation blocks, integrated building core materials, partition walls and the like. 本发明涉及一种大掺量火山灰发泡混凝土材料及其制备方法，该混凝土材料由以下质量份的原材料配
