Description
Technical field
The present invention relates to Portland cement manufacture technology field, and in particular to a kind of environmentally friendly regeneration coagulation for building
Soil and preparation method thereof.
Background technology
With rapid development of economy, in many big cities in China, the waste that building industry produces has been changed to public hazards.This
A little wastes not only cause environment serious destruction, but also the space of existence is being fought for the mankind, and seriously affect country can
Sustainable development.Therefore, exploitation reduces, recycles and utilizes the new technology of waste material of buildings extremely urgent.
Waste material of buildings is generally by broken concrete, nano-pearl rock brick and ceramic tile, sand and dust, sawdust, plastics and waste paper,
Old metal etc. forms.Broken concrete is typically the maximum part of waste material of buildings, by the broken concrete of crushing and screening
It can be used to the natural aggregate that substitutes in concrete or be used to do the basis of road.This type salvage material is just called
Recycled aggregates.Recycled aggregates have been applied successfully in the building industry of some European and American developed countries, but mainly
Apply on the basis of non-structural concrete and road, the application in structural concrete is limited, usually there was only the thick bone of concrete
The 20% of material is recycled aggregates.Mainly due to recycled aggregates, the intensity compared with natural aggregate is low for this, it is porous and
There is higher water absorption rate.This requires add water in concrete batching to increase its fluidity so as to cause maturing
Contract with dry rate and creep increase.For this difficulty for overcoming recycled aggregates to recycle, concrete research personnel are by research
Have been developed for utilizing the method manufacture concrete partition brick of mechanical pressing and the patented technology of paving block.Study hair at the same time
Now utilization rate of the recycled aggregates in structural concrete can be improved using atmospheric steam maintenance technology.
The characteristics of concrete has abundant raw material, cheap, simple production process, thus make its dosage increasing.
Concrete also has the features such as compression strength is high, and durability is good, and strength grade scope is wide at the same time；These features make it use model
Enclose quite varied, not only used in various civil engineerings, be exactly shipbuilding industry, mechanical industry, the exploitation of ocean, geothermal engineering etc.
；In recent years, with China's high-rise building constantly going into operation, the height of high-rise building is constantly refreshed, its sole plate by
Power state constantly aggravates, and structure is more and more thicker, and strength grade of concrete requires higher and higher, and total gel material content is also increasingly
More, hydration heat of concrete is also with regard to higher, so being easy for the cracking for causing super thick structural concrete.
The content of the invention
