Description
Technical field
The invention belongs to building field, relate to a kind of composite building material and application thereof.
Background technology
At present, on market, decorative kind sheet material has plasterboard and calcium silicate board, but such sheet material is suitable only for and does not use year
The decorative kind sheet material that limit requires, is suitable only for interior decoration, and its technical specification such as mechanical property, durable years can not meet country
Its Relevant Technology Standards requirement.The most domestic housing industrialization of vigorously advocating, dry construction operation, no longer use the shape that brick and tile are built by laying bricks or stones
Formula makes monolithic architecture, so needing the mode using plate type assembled to form the interior wall of building, exterior wall, roofing, flooring, but mesh
Front market sheet material cannot meet the plate property of plate type assembled building and use requirement, needs the technology according to building to use standard
Requirement, distinguishes indoor plate and outdoor use plate two big series sheet material, this technical scheme, it is simply that be respectively directed to indoor and outdoors building
With sheet material, the structural lumber of being correlated with targetedly that a kind of new material of design, new production process are made.Cement base plate
Be mainly used in outdoor and the higher floor of waterproof requirement, plaster-based board be mainly used in indoor that water resistance requires every
Wall and decorations.Fill up the blank in domestic construction sheet material market.
Cement base plate is in manufacturing process, and its hardening time and curing time are relatively long, and processing technology and use
Equipment is the most relative complex.Application publication number is that the patent of invention of CN103420653A discloses a kind of High-elastic cement board, mainly
For engineering template and decorating inner and external walls plate.Silicon ash 25 parts, the 1000 above fineness of mesh are added in 100 parts of Portland cements
Rice hull ash 5 parts, the wollastonite in powder of fineness ratio 1:8-10 5 parts, polycarboxylate water-reducer 0.8 part, poly-third fiber 0.8 part, the wood fiber 0.2
Part, polyvinyl alcohol 0.2 part, 50 parts of water, mix and blend, and spread fibrous mesh cloth roll-forming.Although the technical scheme of this invention
Overcome the defect of cement plate fracture resistance difference, but its hardening time is long, it is impossible to use continuous shaping method to produce sheet material, system
Making the cycle long, cost is high.
Summary of the invention
In order to overcome the deficiencies in the prior art, the present invention provides a kind of composite building material and application thereof.
The invention provides following technical scheme:
A kind of composite building material, it is fast hard that described composite building material includes that basestocks, the raw material of described basestocks include
Sulphate aluminium cement and portland cement or include portland cement, slag powders and Gypsum Fibrosum or include quick hardening sulphoaluminate water
Mud, portland cement and Gypsum Fibrosum；The pH value of described composite building material is 7～9 or 12～14, described composite building material soft
