Description
Technical field
The present invention relates to a kind of structure material, more particularly to a kind of foam concrete.
Background technology
Foam concrete is the new coagulation fill material that last decade grows up, and it is the foamed system by foaming machine
Foaming agent is mechanically fully foamed, and foam and cement mortar and other addition materials is full and uniform according to a certain percentage
Mixing, cast-in-place construction then is carried out by the pumping system of foaming machine, the one kind formed through natural curing contains a large amount of closings
The light-duty filling material of stomata.Foam concrete is because with lightweight, that intensity is adjustable, high flowing, low bullet damping property are good etc. is more
The advantage of aspect, makes it be had a good application prospect in traffic engineering, such as Soft Ground, the backfill of bridge (culvert) back of the body, trembles with fear
Freeze earth roadbed heat-insulation and heat-preservation, platform carries on the back banket anti-freeze expansion and widening of subgrade etc..Solving soft soil base sedimentation, bumping at bridge-head, height
Also there is significant advantage in roadbed reclamation, widening project, the problems such as saving the area.But because hardened foam concrete surface is opened
Split, cause to absorb a large amount of external moisture, cause service life to reduce, have impact on its application.
The defects of existing in view of the casting production process of above-mentioned existing conveyor screw, the present inventor are based on being engaged in such production
Product manufacture and design abundant for many years practical experience and professional knowledge, and coordinate the utilization of scientific principle, are actively subject to research and innovation, to
A kind of Novel foam concrete is founded, it is had more practicality.By constantly research, design, and through studying sample repeatedly
And after improving, the present invention having practical value is created finally.
The content of the invention
It is a primary object of the present invention to, the defects of overcoming existing foam concrete to exist, and a kind of new bubble is provided
Foam concrete, cracking resistance is improved, reduce water suction, thus more suitable for practicality, and with the value in industry.
The object of the invention to solve the technical problems is realized using following technical scheme.Itd is proposed according to the present invention
A kind of foam concrete, be made up of each component of following mass ratio, 25~60% cement mortar, 5~15% water, 1~3% subtracts
Aqua, 1~3% plasticizer, 1~5% foaming agent, 0.1~5% inorganic salts, 0.5~5% waterproofing agent, 1~10% clay, 3~
12% additive and 5~25% auxiliary material.
Foregoing foam concrete, the water reducer are that main chain is methacrylic acid, and side chain is the polyester-type of hydroxy-acid group
Structure polycarboxylate water-reducer.
Foregoing foam concrete, the plasticizer are epoxidized soybean oil.
Foregoing foam concrete, the foaming agent be alkyl sulfonic ester, hydroxyalkyl ether sulphonic acid ester, alkyl ether sulfonates,
Hydroxyalkyl ether sulfuric ester, α-olefin sulfonate, alkyl benzene sulfonic acid ester, alkyl sulfate, alkyl ether sulphate, alpha-olefin sulfuric acid
Any one in ester, alkylbenzene sulfuric ester or any two kinds and two or more mixtures.
Foregoing foam concrete, the inorganic salts are calcium chloride, calcium formate, calcium nitrate, calcium stearate, magnesium salts or aluminium
Salt.
Foregoing foam concrete, the waterproofing agent are methyl silicon sodium alcoholate, ethyl sodium silanolate or poly- ethyl hydroxy siloxanes
In one kind.
Foregoing foam concrete, the additive are prestox polyhedral oligomeric silsesquioxane and glass fibre.
Foregoing foam concrete, the auxiliary material are silicon ash, calcium carbonate, slag, flyash, volcanic ash, agstone, wood
Rubber powder, SILICA FUME or their mixture.
By above-mentioned technical proposal, foam concrete of the invention at least has following advantages：
The foam concrete of the present invention is mainly used in caused by solving the existing cracking of current foamed concrete material, water suction
The problem of service life is shorter, wherein plasticizer are more green using epoxidized soybean oil, and auxiliary material is smaller using particle diameter
Material, there is filling concrete mortar gap, improve the advantage of mechanical property；Prestox polyhedral oligomeric sesquialter silicon in additive
Oxygen alkane and glass fibre are worked in coordination, and wherein chopped E-glass fiber surface has more amino, with eight containing epoxy radicals
Methyl polyhedral oligomeric silsesquioxane (poss) reacts, and nano level POSS is well and embedding company occurs for glass fibre,
Equivalent to the prestox polyhedral oligomeric silsesquioxane with dots structure by the table of the chopped E-glass fiber of thick line structure
Bread wraps；Poss surface inertness group has preferable compatibility with Corvic (fine rule structure), in polyvinyl chloride
With good dispersiveness, poss is connected in a manner of being chemically bonded in Corvic organic chain；Therefore, prestox is more
Face body oligomeric silsesquioxane plays good function served as bridge, Jin Erti between chopped E-glass fiber and Corvic
The high mechanical strength of glass fiber material, the effect for playing cracking resistance that can be higher, and then reduce material cracks water suction and cause
The lost of life.Multiple additives work in coordination to obtain the excellent foam concrete of cracking resistance.
