Abstract

The invention belongs to the technical field of energy saving, and discloses an energy-saving environment-friendly building foam cement which is composed of the following substances in percentage by mass: 30-35% of cement, 5-8% of ferronickel slag powder, 2-8% of expanded vermiculite, 2-5% of mica powder, 0.5-1.2% of waterproofing agent, 1.5-2.5% of foaming agent, 0.01-0.05% of multifunctional biological viscosity modifier, 1-2% of modified coir fiber, 1-2% of polycarboxylic acid water reducing agent and the balance of water. The foam cement has the characteristics of favorable waterproofness, high toughness, heat insulation, energy saving and the like, and is green and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of energy saving. Background technique [0002] The energy-saving technology of building wall structure is one of the important directions of building energy-saving research in all countries in the world. The development of high-performance building wall structure insulation materials, products and systems is the key to realizing building energy conservation. Guobanfa [2013] No. 1 Document "Green Building Action Plan" requires: "Accelerate the development of building insulation systems and materials with good fire and heat insulation performance. Foamed cement is a new generation of green and environmentally friendly new non-toxic insulation materials. It has the advantages of light weight, good thermal insulation performance, excellent fire resistance, and good environmental protection. It is widely used in wall insulation, floor heating insulation, roof insulation and other related projects. However, prob...
