Self-insulation system foam concrete and preparation method thereof

Abstract

The invention discloses self-insulation system foam concrete. The self-insulation system foam concrete is prepared from the following raw materials in parts by weight: 20-40 parts of sulphoaluminate cement, 20-40 parts of an animal protein foaming agent, 6-15 parts of sodium alpha-olefin sulfonate, 6-15 parts of lauryl sodium sulfate and 6-15 parts of sodium dodecyl benzene sulfonate. The preparation method comprises the following steps: diluting the animal protein foaming agent, mixing slurry with prepared foam, and then conducting pouring and curing. By adding the ionic animal protein modifier, the stability of the foam is enhanced, porosity is improved, and the thermal insulation property of the foam concrete is improved. The foam concrete is prepared from the sulphoaluminate cement, CO2 emission is reduced, energy is saved, and environment friendliness is achieved; meanwhile, a prepared foam concrete test block is high in porosity; and collapse of the foam in the foam concrete during pouring and curing can be reduced by means of the fast setting property of the sulphoaluminate cement, the heat preservation and heat insulation performance of the foam concrete is good, compressive strength is high, and the application prospect of the foam concrete is wide.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a preparation method of a self-insulation system sulphoaluminate foam concrete. [0002] technical background [0003] my country's energy utilization efficiency is relatively low, and building energy conservation is a requirement for sustainable development. The design and construction of energy-saving buildings is the need for the sustained, rapid and healthy development of my country's national economy, and plays a very important role in my country's economic construction. Compared with ordinary Portland cement, sulphoaluminate cement produces a small amount of carbon dioxide, which meets my country's energy-saving and environmental protection building requirements. At the same time, sulfoaluminate cement is widely used in repairing cement-based materials at present, and its early strength and high strength make up for the lack of strength of foam concrete test blo...

AI Technical Summary

Problems solved by technology

The traditional external mineral content will reduce the mechanical properties of foam concrete. The strength of foam concrete itself is relatively low. Because of the lack of coarse aggregate, its main strength comes from cement hydration products. A certain amount of mineral content is added to replace it. Cement will greatly reduce its strength
