Abstract
The present invention relates to the preparation method that a kind of easy crushing material is manually prepared, it is characterized in that comprising the following steps: the preparation of raw material: the raw material adopted is, cement, clay, and water, described cement, clay, and the mass ratio of water is 250-400:1000:50-560; Afterwards by stirring, compacting and shapingly obtain the finished product.
Description
Technical field
Patent of the present invention relates to the preparation method that a kind of easy crushing material is manually prepared.
Background technology
The preparation of easy crushing material is the fragmentation in order to better study granulated material.Up to the present, the fragmentation for material launches mainly for natural materials, as sand and stockpile etc.But because the character of natural materials particle self is too complicated, such as particle shape is irregular, the difference of material internal joint fissure, and particulate mineral composition is not equal, make the factor much affecting the mechaanical property of materials be coupled to together, be difficult to study the impact of single factors.Therefore, the easy crushing material of artificial preparation becomes a kind of new method, forefathers it is also proposed certain methods for the preparation of easy crushing material, such as adopt the materials such as granulated glass sphere, gypsum rod, quartz particles, agglutination sand to simulate natural materials, the content such as shattering process, mechanical property, constitutive relation of research material.Although the use of these materials have also been obtained some comparatively believable rules; But still there is the problem such as accuracy and reasonableness in range simulation real natural materials.Therefore, we wish, by adopting based on natural materials (clay), to add some artificial materials (cement), prepare the easy crushing material of homogeneous, regular shape, the impact of research single factors commute crushing material mechanical characteristic.
Summary of the invention
The object of patent of the present invention is the preparation method providing a kind of easy crushing material manually to prepare, and it is characterized in that comprising the following steps:
The preparation method that easy crushing material is manually prepared, is characterized in that comprising the following steps:
Step one, the preparation of raw material:
The raw material adopted is, cement, clay, and water, described cement, clay, and the mass ratio of water is 250-400:1000:50-560;
Step 2, stirs:
Be positioned in container by the raw material of step one, stir uniformly, obtain grout, the plastic viscosity of this grout is 0.009Pas.
Step 3, granulate:
The particle that diameter is 20mm pinched into by grout step 2 obtained;
Step 4, compacting:
Particle obtained in step 3 is put into the mould with circular groove, suppresses, the obtained spheroidal particle being of a size of 20mm;
Step 5, shaping:
Spheroidal particle obtained in step 4 is shaped 24 hours shaping, afterwards spheroidal particle is taken out the plastics freshness protection package putting into sealing, as the shady and cool dry place of environment, namely obtains the finished product.
Clay in step one is silty clay, and cement is 32.5R composite Portland cement.
First smear machine oil at the mould with circular groove in step 4, place particle afterwards and be pressed.
Step 5 also comprise to plastics freshness protection package water spray make spheroidal particle moistened surface.
Beneficial effect:
The present invention overcomes the deficiencies in the prior art, provides the preparation method that a kind of easy crushing material is manually prepared, and adopts the compound of silty clay, cement and the water of drying to prepare easy crushing material.In test, by silty clay, cement and water according to after the abundant mix of the proportioning drafted, kneading becomes diameter to be the particle of 20mm, is then positioned over by particle in the mould with circular groove and suppresses.After 24 hours, the cement in sample forms some strength, and template taken off, careful taking-up spheroidal particle puts into the plastics freshness protection package wet curing of sealing, and the time is one month, and like this, the artificial preparation of easy crushing material just completes.Operationally, this method method for making sample is easy, only needs to be ready to mould and material is just passable, and time controling is simple, and external influence factors is few.On product, the material of preparation has the features such as success ratio is high, homogeneity is good.Due to employing is natural silty clay and cement, can be prepared the material with different mechanical characteristic by different proportionings, and the different natural easy crushing material of simulation has some superiority.Indoor triaxial test also shows, lower confined pressure also can observe broken generation, and this meets the character of natural soil nature material.Simultaneously because this product has the good advantage of unicity, in interpretation of result, can avoid because particle shape is irregular, the difference of material internal joint fissure, the interference that the not equal factor of particulate mineral composition causes result, study single factors preferably to the impact of material fragmentation, as granule strength, confined pressure etc.Therefore, can think that the preparation method that easy crushing material is manually prepared is suitable.
Embodiment
Below in conjunction with specific embodiment, set forth the present invention further.
The preparation method that easy crushing material is manually prepared, is characterized in that comprising the following steps:
Step one, the preparation of raw material:
The raw material adopted is, cement, clay, and water, described cement, clay, and the mass ratio of water is 250-400:1000:50-560;
Step 2, stirs:
Be positioned in container by the raw material of step one, stir uniformly, obtain grout, the plastic viscosity of this grout is 0.009Pas.
Step 3, granulate:
The particle that diameter is 20mm pinched into by grout step 2 obtained;
Step 4, compacting:
Particle obtained in step 3 is put into the mould with circular groove, suppresses, the obtained spheroidal particle being of a size of 20mm;
Step 5, shaping:
Spheroidal particle obtained in step 4 is shaped 24 hours shaping, afterwards spheroidal particle is taken out the plastics freshness protection package putting into sealing, as the shady and cool dry place of environment, namely obtains the finished product.
Clay in step one is silty clay, and cement is 32.5R composite Portland cement.
First smear machine oil at the mould with circular groove in step 4, place particle afterwards and be pressed.
Step 5 also comprise to plastics freshness protection package water spray make spheroidal particle moistened surface.
The density of the product obtained is 1.3-1.45g/cm
3.
Concrete proportioning in step one is as described below
Density (the g/cm of sequence number 1-4
3) average is respectively: 1.313,1.347,1.380 and 1.414.
Curing step illustrates:
The easy crushing material product of artificial preparation is due to containing certain cement, therefore its maintenance processes needs to make corresponding amendment with reference to the maintenance of cement products, and concrete suggestion is:
1., after granulation step completes, by circular groove mould (containing particle) as indoor cold and moisture location maintenance 24 hours, if envrionment temperature is lower than 10 degrees Celsius, should, as maintenance in airtight curing room, prevent the too low generation of temperature freezing.
2. after spheroidal particle takes out from mould, if desired the maintenance long period facilitates test arrangement, and envrionment temperature is lower than ten degrees Celsius or higher than 25 degrees Celsius, should by shaped granule as maintenance in pure water, until take out before test.Answer periodic logging curing temperature, Reasonable adjustment care environments simultaneously, guarantee sample maintenance success.
If 3. sample making course is longer, for ensureing that different batches product reaches given strength, rationally should increase preserving period, the time must not be less than 30 days.
Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.
