Abstract
The invention relates to the technical field of recycling clay, in particular to a method for preparing a pavior brick by utilizing clay. The method is characterized by adopting the steps as follows: recycling and purifying waste clay, and air-drying the waste clay to constant weight; detecting the ingredients of the clay; analyzing lithofacies; conducing a clay fineness test and selecting a clay material suitable for use; mixing the selected clay with sand, stone, cement and water by a certain ratio and stirring to form concrete mixture; and enabling the mixture formulated in the former step to be subjected to full hydration reaction and solidification-formation at normal temperature so as to prepare the pavior brick meeting relevant national standard. The invention aims at designing the method for preparing the pavior brick by utilizing clay, transforming the waste clay into a resource for utilization and improving the embarrassed current situation of environmental pollution caused by clay.
Description
One, technical field: the mud that the present invention relates to make pottery is recycled production technical field, exactly is a kind of method of utilizing the clay standby pavior brick of making pottery.

2. technical scheme: the present invention adopts following technical solution.
A kind of method of utilizing the clay standby pavior brick of making pottery, it is characterized in that: it adopts following step to carry out:
(1) to discarded pottery mud reclaim, preliminary election, purifying treatment, deposit air-dry to constant weight;
(2) the pottery mud that step (1) is obtained carries out chemical composition analysis, confirms that chemically reactive meets the demands;
(3) the pottery mud that step (2) is obtained carries out petrographic analysis;
(4) the pottery mud that step (2) is obtained carries out fineness testing;
(5) the pottery mud that step (2), (3) (4) is obtained cooperates by a certain percentage with sand, stone, cement and water, forms glue sand-aggregate mixture;
(6) with the mixture of step (5) preparation, carry out abundant hydration reaction under the normal temperature state, coagulation forming forms stable concrete structure, prepares the pavior brick goods that meet the concerned countries standard.
In the step (1), pottery mud is got rid of the purifying treatment of foreign material, deposit air-dryly to constant weight, avoid mixing with other foreign material, or polluted, guarantee that hydration can fully carry out.
In the step (2), will carry out chemical constituents determination, wherein SiO through purification, air-dry pottery mud to constant weight
2And Al
2O
3Two kinds of compositions are the clay bases for pavior brick of making pottery.
In the step (3), petrographic analysis confirms that pottery mud material forms homogeneity and the stability that distributes, and guarantees that it plays consistently effect in concrete.
In the step (4), by fineness testing, measure the fineness of pottery mud; Fineness should satisfy: 45 μ m square hole sieves tail over less than or equal to 12%.
In the step (5), pottery mud is 10%～40% to the replacement amount of cement by massfraction.
In the step (6), through stirring, the moulding of vibrating, the demoulding and maintenance processes, make the uniform mixing of pottery cement concrete, moulding closely knit, fully stably carry out hydration reaction, prepare the pavior brick goods that meet the concerned countries standard.
3. advantage and effect
In sum, the present invention has the following advantages.
(1) effectively utilize discarded pottery mud, the change waste material is resource, alleviates the environmental pressure of Production of Ceramics enterprise, reduces enterprise's production cost.
(2) use the air-setting technology, will discard pottery mud and process, and transform the pavior brick of social needs, realized the recycling of waste.This invention is the new technology of low-carbon (LC), environmental protection.
(3) utilize the clay standby pavior brick of making pottery, the product properties is stable, and meets the concerned countries standard-required.Can realize continuous industry production, produce and stablize, good product quality.
(4) pavior brick is the product that the urban municipal construction needs in a large number, and utilizes the clay standby pavior brick of making pottery, and is lower than traditional pavior brick production cost, like this, and from alleviating economically the pressure of urban municipal construction.
(5) the present invention not only makes pottery mud be reused, and replaces cement, reduces the cement usage quantity, has greatly saved the production cost of preparation pavior brick, has economic implications.Alleviate the problems such as resources and environment of the production of cement.And, efficiently solve the environmental problem that discarded pottery mud causes, have good social effect.
Four, description of drawings: Fig. 1 is process flow sheet of the present invention.
Five, embodiment:
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the process route chart of embodiment.
As shown in Figure 1, embodiment cooperates the decontamination of pottery mud, categorizing selection and air-dry processing with sand, stone, cement and water etc. after processing by a certain percentage, through processes such as stirring, moulding, maintenances, utilizes the air-setting technology to prepare pavior brick.Wherein, the purpose of (1) decontamination, categorizing selection and air-dry processing is to obtain uniform component, stable, is beneficial to the pottery mud that carries out hydration reaction.Pottery mud is in drying regime, is easy on the one hand the stirring moulding of mixture, is conducive on the other hand control the water consumption of preparation pavior brick; The effect of (2) stirring.Stirring makes before the moulding in the mixture various components evenly mix; The effect of (3) vibrating.Vibrate and make the closely knit moulding of goods energy; (4) effect of maintenance.Maintenance can be carried out normal aquation, condenses and harden after making the mixture moulding, and goods have uniformly densely internal structure and higher intensity after the sclerosis.
