Description
Technical field
The present invention relates to a kind of concrete hollow partition plate and its method of preparation, in particular to a kind of sharp waste concrete is empty
Septum cordis wallboard and preparation method thereof field.
Background technique
With the propulsion of country's building housing industrialization, as precast light wall matched with skyscraper, frame structure
Plate is increasingly becoming the chief component of current materials for wall and the development trend of certainty.Concrete hollow partition plate can be used as filling
Internal partition wall with formula building uses, and has from heavy and light, good heat preservation performance, and shock resistance is good, construction and installation are convenient and efficient, increases interior makes
With area, labor intensity is reduced, improves construction quality, the advantages that cost is moderate.
With accelerating for Chinese Urbanization, building waste, in the trend risen, but generally existing is at present built in China
The not high phenomenon of building refuse utilization rate, nowadays building waste processing mode mainly keeps in stacking and landfill stabilization.To old mixed
The recycling for coagulating soil does not cause enough attention also, with the sharp increase of China's building waste quantity, building waste resource
Change processing is extremely urgent.The water quenching waste residue that small furnace ferronickel slag generates when being smelting ferronickel, activity is low compared with slag,
Admixture dosage as cement is seldom, and utilization rate is low, causes bulk deposition, pollutes environment.But due to small furnace ferronickel slag
Itself specific gravity is lighter, can be used as construction material aglite carry out using.
Currently, industrial residue is in hollow partition board using being broadly divided into following a few classes: (1) big, light weight, work by particle
The low waste residue of property is utilized in concrete hollow partition plate as light-weight aggregate;(2) the high waste residue of activity is then milled, and utilizes it
The volcano ash effect that has as gelling material carry out using;(3) small waste residue is then used as filler to be filled out to the low, particle of activity again
It fills, plays humidification.In addition then haydite can also be carried out to prepare concrete hollow partition as lightweight aggregate with precast ceramsite
Plate.Such as: CN1194929C " production method of mechanically from industrial cinder, ceramsite concrete light-weight partition board ": what is involved is utilize industry ash
Slag and haydite are the method that light aggregate prepares partition plate, belong to waste utilization;CN1207441A " machine-made compound light partition item
Plate ": what is involved is the methods for preparing light partition board with perlite, clinker, slag etc. for primary raw material;CN101759402A
" a kind of concrete fireproof hollow lath ": what is involved is be main with fire-proof cement, flyash, fire resistant infilling, expanded perlite
The method that raw material prepares concrete fireproof hollow lath.But these wallboards are generally existing at high cost, complex process, and intensity is low etc.
Disadvantage.
Summary of the invention
