Description
Technical field
The invention discloses a kind of preparation method of hydraulic stone putty material, belong to building material technical field.
With the enhancing that the development of urbanization process and historical protective are realized, the Old City Wall in city is just increasingly subject to people
Attention, Old City Wall repair work carry out extensively.The repairing of ancient building and maintenance are universally acknowledged problems, Britain's landmark
Itd is proposed with conservation of historic sites association chairman B.M.Feilden in landmark maintenance work, Old City Wall is repaired and must followed
Ancient method is carried out, and is reduced the otherness of new and old material, is avoided causing the change of structure behavior and destroying the safety of inhering architecture.I
The most of Old City Walls of state use lime to prove that its performance is extremely excellent through historical practice as binder materials when building.
Therefore, calcium carbonate patching material is still preferentially elected in the repairerment of Old City Wall.However, the early strength of air hardening lime material
Low, it is slow to condense hardening, and cubic deformation is big during hardening and poor water resistance, is easily decomposed under moist or underwater environment defeated and dispersed, uses effect
Fruit is undesirable.It is that cement is gentle in rehabilitating historic building and hydraulic lime has the multifrequency nature of cement and air hardening lime concurrently
The irreplaceable patching material of hydraulic lime, and will play great effect in the rehabilitating historic building in future.But hydraulic
Property lime material yet there is mechanical property it is bad the problem of, therefore also need to study it, to be that ancient architecture reparation is used
The design of hydraulic stone putty material, preparation, using providing theoretical direction.
The content of the invention
The present invention solves the technical problem of：For traditional hydraulic lime material mechanical performance it is bad the problem of, there is provided
A kind of preparation method of hydraulic stone putty material.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
（1）Waste and old concrete is crushed, is sieved, is obtained waste and old concrete powder, waste and old concrete powder is calcined, must be pre-processed useless
Old concrete powder；
（2）Saturated sodium bicarbonate solution in mass ratio 1 when will pre-process waste and old concrete powder and 50 DEG C：10~1：15 mixing leachings
Bubble, cool, filter, dry, obtain modified waste concrete powder；

Mixing, obtains hydraulic stone putty material.
Step（2）The method of the preparation of saturated sodium bicarbonate solution is heated to add water in beaker at described 50 DEG C
Coolant-temperature gage is 50 DEG C, and sodium acid carbonate is added into beaker, until there is crystal precipitation, is filtered, saturated sodium bicarbonate is molten when obtaining 50 DEG C
Liquid.
Step（6）The slag powder is in S95 levels ground granulated blast-furnace slag or S105 level ground granulated blast-furnace slags
Any one.
Step（6）The cohesive resist is the derivative of methyl acrylate-acrylic acid hydroxypropyl ester copolymer.
Step（6）The thixotroping resist is attapulgite powder.
