Description
Technical field
The invention discloses a kind of preparation methods of haydite concrete, belong to building material technical field.
Background technology
With the progress and development of modern building technology, skyscraper and large-span structure it is more and more common, we are to mixed
The requirement of solidifying soil nature energy becomes increasingly harsher.This makes there is excellent working performance, high intensity, lightweight, multi-functional height
Performance light aggregate concrete has extraordinary application prospect and huge development potentiality in longspan structure and skyscraper.
Haydite concrete is as the molecule in light aggregate concrete family, and with light-weight, relative intensity is higher, heat preservation and insulation
Well, the advantages that frost resistance and good fire resistance, it is widely used in science of bridge building and civil building engineering.Haydite is one kind in high temperature item
Part（1100 DEG C~1200 DEG C）Artificial lightweight aggregate made of lower sintering grow can be divided into shale pottery according to the difference of material category
Grain, leca, lytag.Haydite concrete is to be equipped with the fine aggregates such as normal sands and gelling material using haydite as coarse aggregate
Concrete made of material, belongs to lightweight aggregate concrete.Haydite concrete is divided into haydites of book structure coagulation according to the difference of haydite kind
Soil, leca concrete, flyash-haydite concrete, usual density rating are 200~1950kg/m3, and strength grade is
LC5.0~LC60.For haydite concrete as a kind of lightweight concrete, interior porosity is larger, and heat preservation and insulation is good, used in building
Good insulation, energy saving effect can be played by building exterior wall, roof.Under geological process, architecture quality is bigger, according to
Inertia force F=ma, structure effect caused by sympathetic earthquakes effect
It is bigger, prodigious destruction will be generated to structure.It is small using haydite concrete density, the characteristics of light weight make every
The nonload bearing elements such as wall, filling wall can reduce the dead weight of building, can effectively mitigate earthquake zone to a certain extent in this way
Adverse effect.Further, since the water imbibition of haydite itself, carries out pre-wetted treatment to haydite, can be played in inside concrete " interior
The effect of maintenance ", to reduce concrete crack caused by dry shrink.There are water absorbing properties for traditional ceramic concrete
High, compressive property deficiency disadvantage.
Therefore, how to improve traditional ceramic concrete there are water absorbing properties that high, permeance property is poor, compressive property is insufficient
Disadvantage is that it is promoted and applies, meets industrial production demand urgent problem to be solved to obtain the raising of more high combination property.
Invention content
The present invention solves the technical problem of：Not for traditional ceramic concrete water absorbing properties height, compressive property
The problem of foot, provides a kind of preparation method of haydite concrete.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
（1）By haydite and water in mass ratio 1：8~1：10 mixing are impregnated, and are filtered, and drying obtains pretreatment haydite, and pretreatment is made pottery

Grain and chitosan solution in mass ratio 1：5~1：8 mixing, filtering obtain 2 modified haydites；
（4）By paraffin and ethyl orthosilicate in mass ratio 5：1~3：1 mixing, Freezing smashing obtain additive；
（5）It counts, weighs successively in parts by weight：80~120 parts of cement, 20~30 parts of flyash, 50~60 parts of 2 modified potteries
Grain, 10~15 parts of additives, 70~90 parts of water and 5~12 parts of water-reducing agents, cement are mixed with water, and sequentially add water-reducing agent,
Flyash, additive and 2 modified haydites, after being stirred, obtain haydite concrete.
Step（2）It is by glucose and water in mass ratio 3 that the Bacillus pasteurii, which hangs bacterium solution,：1000~5：1000 is mixed
It closes, and the beef extract of 2~3 times of glucose quality is added, 1~2 times of the peptone and glucose quality that 2~4 times of glucose quality
Sodium chloride, after being stirred, culture solution is obtained, by culture solution and Bacillus pasteurii in mass ratio 1000：2~1000：3 is mixed
It closes, after cultivating 20~25h, centrifuges, and remove supernatant liquor, obtain Bacillus pasteurii and hang bacterium solution.
Step（3）The graphene oxide mixture is by graphene oxide and water in mass ratio 1：300~1：600 is mixed
It closes, and adjusts pH to neutrality, obtain graphene oxide mixture.

4.0~4.5, obtain chitosan solution.
Step（4）The paraffin is the mineral wax mixture that carbon atom number is 28~36.
Step（5）The water-reducing agent is any one in sodium lignin sulfonate or melamine based water reducer.
The beneficial effects of the invention are as follows：
The present invention is modified the haydite of addition when preparing haydite concrete twice, and first, haydite process is primary modified,
Deposition has hollow calcium carbonate inside haydite, to make the weight of haydite increase, and then the lamination of product is made to reduce, and
Due to the addition of hollow calcium carbonate, haydite boring is meandering, to make the water imbibition of haydite reduce, and carries to a certain extent
The high mechanical property of haydite, and then the slump of product is made to reduce, Anti-pressure can improve, and secondly, haydite changes process is secondary
Property after, be coated on the outside of haydite graphene oxide can chitosan, since deposition has calcium carbonate inside haydite, to make graphite oxide
