Description
Technical field
The invention belongs to building material field, be specifically related to the insulation block that a kind of recycled aggregate of waste concrete produces
Block.
Background technology
Saving the strategic emphasis that the energy is China's economic development, specifically at building materials field, within 1986, Minstry of Housing and Urban-Rural Development of People Republic of China (MOHURD) promulgates
" Civil Building Energy Conservation design standard ", on October 1st, 2001, Minstry of Housing and Urban-Rural Development of People Republic of China (MOHURD) has issued that " hot-summer and cold-winter area is lived and built
Saving energy design in a building standard ".From 2000, the reducing energy consumption work of the existing building big to heating zone thermal environment difference or energy consumption
Having begun to, within 2005, country starts reducing energy consumption in key cities.Development of Novel construction material is to reduce building
The energy of building enclosure runs off, and is one of major measure improving building energy utilization ratio.
Summary of the invention
