Description
Technical field
The present invention relates to a kind of concrete segment, relate in particular to a kind of light aggregate concrete building block, belong to the new building material field.
Background technology
The further raising that requires along with building energy conservation and build further developing of high stratification trend, the light wall material with self-heat conserving performance will more and more get the nod.Traditional external wall outer insulation more and more shows weak point, especially on fire line, heat retaining property.The patent No. is 200510061387.2 Chinese invention patent, discloses a kind of high strength light concrete building block and manufacture method thereof.A kind of lightweight concrete building block, it is characterized in that containing in the raw material cement, flyash, air entrapment agent and light coarse aggregate, water reducer, economization agent, the weight percentage of described cement is 10～30%, the weight percentage of described air entrapment agent is 0.1～0.5%, described water reducer is 0.25～1.5% of a cement weight, described economization agent is 0.25～1.5% of a cement weight, the weight percentage of described light coarse aggregate is 30～70%, all the other are flyash, and described light coarse aggregate is that particle diameter is not more than 800kg/m greater than 5mm, apparent particle density
3Aglite.The manufacture method of high strength light concrete building block, it is characterized in that and to send into stirrer after cement, flyash, water reducer, economization agent and the water metering, air entrapment agent adds stirrer after adopting mechanical foaming, add light coarse aggregate again and after stirring, send into pouring truck, moulding then, under 20～40 ℃ environment, rested 8～16 hours, after mechanical sawing, in curing kilns under 60～90 ℃ environment steam-cured 8～16 hours or in autoclave with the logical steam steam press maintenance of the pressure of 0.4～2MPa 6～12 hours.But its cement slurry and coarse aggregate performance difference are very big, so need in the prescription to infiltrate a certain amount of economization agent and water reducer, have improved production cost.
Summary of the invention
The objective of the invention is provides a kind of light aggregate concrete building block for solving the problems of the technologies described above.
Above-mentioned technical purpose of the present invention is achieved by the following technical programs:
A kind of light aggregate concrete building block is characterized in that containing in the raw material cement, light-weight aggregate, super-light aggregate and flyash and water; Wherein, light-weight aggregate is meant that apparent density is 450～650Kg/m
3Particle diameter is the sintering ceramsite of 5～50mm, and super-light aggregate is meant that apparent density is 300 Kg/m
3In following perlite, glass bead, the granular polystyrene one or more; Flyash is meant I level or II level flyash.
Central principle of the present invention is to be the drying shrinkage of light-weight aggregate adjustment building block with the haydite through high temperature sintering; pour into a mould molding with cement and flyash as gelling material; reduce weight with super-light aggregates such as perlite, glass bead or granular polystyrenes; improve heat-insulating property, control drying shrinkage of the present invention and ultimate compression strength further with the interaction of described light-weight aggregate, super-light aggregate and cement, flyash.
Among the present invention, super-light aggregate improves block insulation sound damping media base and exists not only as reducing the building block deadweight, and it also exists as a kind of improvement medium of ultimate compression strength, and it is helping building block that the ultimate compression strength of self is improved.Sintering ceramsite is as a kind of light-weight aggregate, have self intensity height, but its adhesive property neither be very desirable under by the condition of cement, flyash each other, that is to say, under the non-existent condition of super-light aggregate, the present invention may also can run into ultimate compression strength problem on the low side.Among the present invention, bond by super-light aggregate and cement, flyash between light-weight aggregate and the light-weight aggregate, improved adhesive property effectively; And the more important thing is that super-light aggregate can help dispersive stress of the present invention, with further raising ultimate compression strength.
The big characteristic of among the present invention another is under the condition that does not add economization agent and water reducer, can reach good dried shrinking percentage equally.It is based on following theoretical realization: it is because cement slurry is big with the performance difference that gathers materials that prior art why need water reducer and economization agent to control to be done shrinking percentage, does something against one's will; And the reason of cement slurry and the performance difference that gathers materials not only relates to material itself but also relate to the attribute of goods.Suppose that the patent No. is 200510061387.2 Chinese invention patent, it does not add air entrapment agent, does not have water reducer and economization agent yet, and its drying shrinkage can be accepted reluctantly so.The present invention is by improving selecting materials of light-weight aggregate, and with the means that super-light aggregate is replaced air entrapment agent, realized under the condition that does not add economization agent and water reducer, can reach good dried shrinking percentage equally.
Preferred as technique scheme, the cement content in the raw material are that the content of 10～40wt%, light-weight aggregate is that the content of 30～50wt%, super-light aggregate is 1～20wt%.
Preferred as technique scheme, the cement content in the raw material are that the content of 20～30wt%, light-weight aggregate is that the content of 40～50wt%, super-light aggregate is 5～10wt%.
Preferred as technique scheme also contains silane coupling agent in the raw material.
Silane coupling agent is as a kind of expansion component, it utilizes the reaction of the active group generation of silane and basic material, reactive hydrogen on the displacement organic molecule, can after a few hours, begin release portion hydrogen, in cement slurry, form micro-bubble, general hole diameter below 0.1mm, thereby make concrete produce the volume microdilatancy, to compensate concrete volumetric shrinkage of this stage.It and simple aluminium powder aerating different in kind, because the coupling agent effect of alkane silicidation technique, make the hydrolysising group and the inorganic materials reaction of Siliciumatom one end, the non-decomposition organo-functional group of the other end and the reaction of the active group of organosilicon material, thereby form molecular linkage at these two kinds original inert storerooms mutually, they are combined firmly, be meant the cohesive force, intensity, hydrophobicity and the ageing-resistant performance that improve this material widely.Therefore, after adding silane coupling agent, the performance of each side of the present invention all further promotes, as sound insulation, ultimate compression strength, dried shrinking percentage.
Preferred as technique scheme, the content of described silane coupling agent is 0.1～1.0wt%.
In sum, the present invention has following beneficial effect:
The present invention chooses by the science of material, makes goods have good sound insulation, ultimate compression strength, does the shrinking percentage performance.
