Description
Technical field
The invention belongs to building material cement industry laboratory technique field more particularly to a kind of methods tested test cake and made.
Background technology
Many building material industry cement production enterprises and R＆D institution are, it is necessary to carry out various burning clinker of cement research examinations in laboratory
It tests, often needs that the test block of definite shape and certain mechanical strength for raw material is made, be contained on the good container of heat-resisting and thermostabilization
（It is influenced for guarantee test from container contents, often uses platinum piece）, then insert in testing furnace according to the experiment temperature of regulation
Degree system carries out calcining and obtains experiment clinker, and chemical composition analysis, physical property detection and structural research etc. are carried out to it.
Patent No. CN103926126B, applying date 2014-04-29 disclose a kind of side of cement slurry tabletting
Method, which is characterized in that comprise the following steps：The lower platen is placed on pedestal, lantern ring is allowed to be inserted in lower platen and while insertion
The groove of pedestal；The uniform cement slurry of mix is poured into micro-vibration in lantern ring, is uniformly distributed the raw material in lantern ring, Ran Houxiang
Top board is put into lantern ring, is integrally placed under forcing press, carries out pressure tabletting；Whole device inversion is come after the completion of tabletting,
Micro-vibration removes pedestal, lower platen, raw material piece, lantern ring, top board, that is, completes the tabletting of cement slurry successively.
After above-mentioned patent is pressed by forcing press, remove pedestal, lower platen, raw material piece, lantern ring, top board successively, i.e., it is complete
Into the tabletting of cement slurry.But several raw meal powders do not add certain adhesive or have added film-making after adhesive（Cake processed）When as press
The pressure and pressure duration that power machine applies are inadequate, can cause tabletting（Test cake）Loosely, picking or breakage phenomenon, if while pressing
Piece is blocked up, is not easy to grill thoroughly when tabletting can be caused to calcine or calcination time is long.It all can influence to test in various degree above or test
The accuracy of data.
The content of the invention
It is an object of the invention to overcome the above-mentioned problems in the prior art, a kind of side for making experiment test cake is provided
The dry raw meal powder prepared is added in make adhesive to water of the experiment without influence first, after uniformly mixing and stirring, claimed by method according to a certain percentage
The mix raw material of certain mass is taken to insert in special mold, are then pressed on forcing press by mold to it, when pressure has
Enough pressure and pressure duration make the test cake produced have enough physical strengths, and pine does not occur when carrying mobile
It dissipates, picking, breakage phenomenon.Multiple wet test cakes can be made in repetitive operation, by its in electrically heated drying cabinet drying to meet examination

Raw material one
Table one
Raw material two
Table two
Table one and table two list the data to being detected during two different raw material cakes, it is seen that, with pressure increases, constant pressure when
Between extension, the unit weight of test cake increases, and compactness increase, breaking force also increased.The same device that breaking force passes through design
It is measured.In above-mentioned table one, raw material one are a kind of silicate cement raw material, and raw material two are sulphate aluminium cement raw material in table two
（Containing aluminium slag ash）.
Breaking force and the physical property of raw material itself have sizable relation, such as material therefor, fineness, clay content
Deng.
Certain raw material test cake different temperatures, thickness results for calcination table：
Calcining effect is evaluated by the free calcium height in final clinker, is reacted more completely in the low characterization clinker of free calcium,
It is on the contrary then for relatively incompletely.
It can be seen that calcining heat raises, clinker free calcium reduces, and test cake thickness increases, free calcium rise；Calcination time
Extend, free calcium also reduces.
