Effect example
1. The water absorption rates of the clay sintered bricks prepared in example 1 and comparative examples 1 to 10 were measured respectively, and the water absorption rate measurement standard of the clay sintered bricks was carried out according to GB/T8488-2008 "acid resistant brick", and the water permeability coefficient measurement standard was carried out according to GB/T25993-2010 "permeable pavement bricks and permeable pavement slabs". The results are shown in Table 2 below:
TABLE 2 Water absorption and Water permeability coefficients of ceramic sintered bricks
As can be seen from the above table, the water absorption of the resulting clay baked brick was far lower than that of the clay baked brick obtained when the aggregate particle size of comparative example 1 was 3mm, whereas the baked brick was inferior in molding and too rough in surface when the aggregate particle size of comparative example 2 was adjusted to 5 mm.
In comparative example 6, the green bricks were directly put into a drying room, dried at a high temperature of 400 c, then fired, and in comparative example 7, the temperature was gradually increased from room temperature to 300 c for 5 days, then dried, and then fired at 900 c for 24 hours, to obtain a clay sintered brick having a lower water absorption than that of the clay sintered brick obtained in example 1, which was gradually increased from room temperature to 100 c, dried at a temperature of 100 c for 3 days, then dried at 100 c for 2 days, and then fired at 950 c for 24 hours. In comparative example 8, the temperature was gradually increased to 50℃from room temperature, and as a result, the integral molding of the brick was poor and easy to break. In comparative examples 9 to 10, the water absorption of the obtained baked brick was smaller than that of example 1 by gradually increasing the room temperature to 150℃and 200℃during baking.
When the aggregate proportion of comparative example 3 was 20%, the water absorption of the obtained clay baked brick was much lower than that of the clay baked brick obtained when the aggregate proportion of comparative example 4 was 30% and the aggregate proportion of example 1 was 40%, whereas when the aggregate proportion of comparative example 5 was adjusted to 50%, the baked brick could not be molded.
Meanwhile, the invention discovers that the firing temperature of the aggregate can also influence the water absorption and other properties of the finally prepared clay sintered brick to a great extent. The comparison experiment result combined with the invention shows that in the preparation process of the clay sintered brick provided by the invention, parameters such as the particle size of the aggregate, the firing temperature of the aggregate, the addition proportion of the aggregate, the specific drying process, the firing process and the like in the step (4) all have different degrees of influence on performances such as the water absorption rate and the like of the finally obtained clay sintered brick.
2. Under laboratory conditions, simulated terraces were made using the clay baked bricks and the sand cushions of example 1, and the water absorption and water permeability coefficients of the simulated terraces obtained from the different sand cushions were measured.
The specific method for detecting the water absorption rate comprises the following steps: according to the fermentation bin terrace paving method, manufacturing a corresponding cushion layer, airing for 2 days, paving a clay brick to form a imitated terrace (the clay brick is dried to constant weight), and weighing the weight m of the imitated terrace 0 Adding water on the imitated terraces until the micro-seepage water comes out, and calculating the water absorption weight m under different imitated terraces 1 The water absorption W under different simulated floor conditions was estimated as follows:
W＝(m 1 /m 0 )％
the specific method for detecting the water permeability coefficient comprises the following steps: according to the fermentation bin terrace laying method, corresponding cushion layers are manufactured, the cushion layers are dried for 2 days, the clay bricks are laid to form imitated terraces (the clay bricks are dried to constant weight), the imitated terraces are put into a container with holes, enough water (the adding amount of each terrace is the same) is added, the penetrating time is 2 hours, a hole plug is opened, the penetrating water weight Q is collected and weighed, and the water permeability coefficient under different imitated terraces is estimated according to the following mode:
k＝QL/At
q-the amount of water exuded in ml;
l-terrace thickness in cm;
a-floor surface area in cm 2 ；
T-time, in s;
table 3 floor water absorption and permeability coefficients
| Terrace class | Water absorption percentage% | Coefficient of water permeability cm/s |
| Analog terrace 1 | 21.2％ | 0.49*10 -3 |
| Analog terrace 2 | 18.6％ | 0.47*10 -3 |
| Simulation terrace 3 | 17.2％ | 0.43*10 -3 |
| Analog terrace 4 | 11.6％ | 0.3*10 -3 |
| Simulation terrace 5 | 14.2％ | 0.36*10 -3 |
| Analog terrace 6 | 15.8％ | 0.40*10 -3 |
| Analog terrace 7 | 15.4％ | 0.39*10 -3 |
Note that: (1) The sand and stone cushion layers in the simulated terraces 1, 2 and 3 correspond to the sand and stone cushion layer 1, the sand and stone cushion layer 2 and the sand and stone cushion layer 3 in the embodiment 2 respectively.
(2) The simulated terrace 4 corresponds to comparative example 11, 4 kg of clay sintered brick fine powder, 4 kg of water and 2 kg of cement are uniformly mixed to prepare a cement slurry cement ratio bonding layer, a cement slurry cement ratio bonding layer with the thickness of 15mm is paved, and then clay sintered bricks with the thickness of 5.5cm are paved.
(3) The sand cushions in the simulated terraces 5, 6, 7 correspond to those described in comparative examples 12, 13, 14, respectively.
As a result, as shown in the above table, the step of laying the sand and stone cushions was omitted from comparative example 11, and the proportions of the sand and stone cushions 4 to 6 of comparative examples 12 to 14 were different, and the water absorption rates of the simulated terraces without sand and stone cushions and the simulated terraces with sand and stone cushions 4 to 6 were smaller than those of the simulated terraces with sand and stone cushions 1 to 3 of example 3.
In addition, when the stone chips and the crushed stones are absent in comparative examples 15 and 16, respectively, the obtained mixture is easy to shake when being piled up, is unstable, cannot form a stable sand and stone cushion, cannot prepare a corresponding terrace, and therefore, the water absorption test experiment is not performed.
That is, the comparative experiments further show that in the preparation process of the sand and stone cushion, parameters such as different particle diameters, different adding proportions and the like of the second and first broken stones and the stone scraps can influence the related performance of the sand and stone cushion.
3. The clay sintered brick prepared in example 1 and the bentonite sintered brick prepared in comparative example 17 were each tested for 5 indexes of water absorption, water permeability coefficient, flexural strength, wear resistance and acid resistance, and the test results are shown in table 4.
The detection standard for detecting the water permeability coefficient, the flexural strength, the wear resistance and the acid resistance is implemented by referring to relevant indexes of GB/T25993-2010 'water permeable pavement bricks and water permeable pavement boards', GB/T2542-2012 'wall brick experiment method', JT/G3450-2019 'highway subgrade and pavement field test procedure', GB/T12988-2009 'inorganic ground material wear resistance test method'.
The water absorption rate detection standard of the clay sintered brick is implemented according to GB/T8488-2008 acid-proof brick, and the water permeability coefficient detection standard is implemented according to GB/T25993-2010 water permeable pavement brick and water permeable pavement slab.
TABLE 4 comparison of physical Properties index of Clay baked brick and Trinity
Note that: the flexural strength refers to the ultimate breaking stress of the material when the unit area of the material bears bending moment, also called bending strength and breaking modulus, and the larger the flexural strength is, the less likely the material is broken; the wear resistance is characterized by the length of the grinding pit formed under a certain friction force, and the larger the grinding pit length is, the worse the wear resistance is.
It is seen that although the water absorption and water permeability coefficient of the clay sintered brick are smaller than those of the tri-clay, the wear resistance, breaking strength and acid resistance are higher than those of the tri-clay, in order to obtain the integral water absorption and water permeability coefficient of the clay sintered terrace consistent with those of the tri-clay terrace, a sand and stone cushion layer with better water absorption and air permeability is manufactured, but the sand and stone cushion layer is not suitable for the shoveling process operation in a fermentation bin and cannot be directly used as the terrace of the fermentation bin. Therefore, the sand and stone cushion layer and the clay sintered brick paved above the sand and stone cushion layer are integrally used as the fermentation bin terrace, so that the water absorption rate of the fermentation bin terrace can be improved, and meanwhile, the conventional process in the building industry is met, and the terrace is more stable and durable. By comparing the air temperature and the air relative humidity of the fermentation bin when the two terraces are turned over once, whether the physical characteristics of the two terraces, such as water absorption and the like, are consistent is verified.
4. Based on the result in the above "3", the water absorption and the water permeability coefficient of the clay baked brick are different from those of the clay itself to a certain extent, so that in order to make the indexes such as the overall water absorption and the water permeability coefficient of the terrace paved by the clay baked brick consistent with the related parameters of the terrace paved by the existing clay, the preparation of the terrace is carried out by combining the clay baked brick with the sand and stone cushion, as shown in the embodiment 2, the preparation of the curved terrace is carried out by combining the sand and stone cushion with better water absorption and air permeability with the clay baked brick (the embodiment 3). Based on the above, the air humidity during primary turning, the air temperature during primary turning, the primary turning temperature of the terrace and the secondary turning temperature of the terrace of the starter making fermentation bin terrace 2 prepared in example 3 and the fermentation bin terrace prepared in comparative example 17 are further detected respectively, and specifically are as follows:
and (3) detecting air humidity: and detecting the air humidity in the fermentation bin by using a hygrothermograph for scientific research. Before one-time turning, the fermentation bin is always in a closed state, the relative humidity of air in the fermentation bin reflects the water absorption and water permeability of the terrace to a certain extent during one-time turning, and the relative humidity of the two terraces during one-time turning is compared. As shown in figure 1, the air relative humidity of the two terraces is extremely poor and is 2.0, the air relative humidity of the two terraces is 82.7 in 1 to 7 rounds of starter propagation, and the air relative humidity of the two terraces is uniform as a whole, namely, the air humidity of the terrace fermentation bin can meet the air humidity requirement of the fermentation bin of the three-layer terrace.
And (3) detecting the air temperature: and detecting the air temperature in the fermentation bin by using an electronic thermometer. Before primary turning, the fermentation bin is always in a closed state, the temperature in the fermentation bin reflects the fermentation condition of the yeast block to a certain extent during primary turning, and the temperature change of the fermentation bin is compared with that of two terraces during primary turning. As shown in figure 2, the air temperature difference of the two terrace fermentation bins is 0.4 ℃, the temperature difference average value is 0.26 ℃, the whole terrace fermentation bins are consistent, and the terrace fermentation bin temperature can meet the requirements of primary turning temperature and secondary turning temperature of the three-layer terrace fermentation bin.
Detecting the primary turning temperature of the terrace: and detecting the fermentation temperature of the yeast block when the yeast block turns over for one time by using an electronic thermometer. The high-temperature Daqu fermentation of Maotai-flavor liquor is mainly characterized in that the primary turning temperature is higher than 60 ℃. The detection result is shown in figure 3, the primary bending temperature of the clay sintered brick terrace meets the process requirement, the primary bending temperature of the two terraces is extremely poor by 0.7 ℃, the temperature difference average value is 0.38 ℃, and the terraces are integrally consistent.
Detecting the secondary turning temperature of the terrace: and detecting the fermentation temperature of the yeast blocks during secondary yeast turning by using an electronic thermometer. The high-temperature Daqu fermentation of Maotai-flavor liquor is mainly characterized in that the secondary turning temperature is 50-55 ℃. The detection result is shown in figure 4, the secondary turning temperature of the clay sintered brick terrace meets the process requirement, the secondary turning temperature of the two terraces is extremely poor by 0.8 ℃, the temperature difference average value is 0.44 ℃, and the terraces are integrally consistent. The primary turning temperature and the secondary turning temperature of the terrace fermentation bin paved by the method can meet the requirements of the primary turning temperature and the secondary turning temperature of the tri-compound terrace fermentation bin.
