Embodiment 1

[0026] A method for preparing environmentally friendly ceramic clear water bricks by utilizing the sediments of the Yellow River, which comprises the following steps:

[0027] 1) Billet preparation: excavate the Yellow River sediment in the Binzhou section of Shandong from the riverbed, and stack it by the river for 15 years to become the Yellow River sedimentary sediment (fully weathered); when used, if the moisture content exceeds 5wt%, the Yellow River sedimentary sediment The sand is dried on a chain plate dryer to a moisture content of less than 5wt% (weight); the coal gangue and the flux are respectively crushed to 1mm with a jaw crusher, and the clinker is crushed to 1mm for use;

[0028] By weight percentage: 60% of sediment deposited in the Yellow River, 10% of fly ash, 10% of coal gangue, 10% of flux, and 10% of clinker; material, spare;

[0029] Add the sediment, fly ash, coal gangue, flux and clinker deposited by the Yellow River into the twin-shaft mixer, and the...

Embodiment 2

[0038] A method for preparing environmentally friendly ceramic clear water bricks by utilizing the sediments of the Yellow River, which comprises the following steps:

[0039] 1) Billet preparation: The Yellow River sediment in the East A section of Shandong Province was dug out from the river bed and stacked on the riverside for 12 years to become the Yellow River sedimentary sediment (fully weathered); when used, if the moisture content exceeds 5wt%, the Yellow River sedimentary sediment The sand is dried on a chain plate dryer to a moisture content of less than 5wt% (weight); the coal gangue and flux are respectively crushed to less than 1mm with a roller crusher, and the clinker is crushed to 1.5mm for use;

[0040] By weight percentage: 80% of sediment deposited in the Yellow River, 5% of fly ash, 5% of coal gangue, 5% of flux, and 5% of clinker; material, spare;

[0041] Add the sediment, fly ash, coal gangue, flux and clinker deposited by the Yellow River into the twin...

Embodiment 3

[0050] A method for preparing environmentally friendly ceramic clear water bricks by utilizing the sediments of the Yellow River, which comprises the following steps:

[0051] 1) Billet preparation: The Yellow River sediment was dug out of the river bed, and was stacked on the riverside for 20 years to become the Yellow River sedimentary sediment (fully weathered); then the Yellow River sedimentary sediment was dried on a chain plate dryer to a moisture content of 4wt% ( weight); use jaw crusher to crush coal gangue and flux to 0.8mm respectively, and crush clinker to 1mm for standby;

[0052] By weight percentage: 70% of sediment deposited in the Yellow River, 8% of fly ash, 8% of coal gangue, 7% of flux, and 7% of clinker; material, spare;

[0053] Add the sediment, fly ash, coal gangue, flux and clinker deposited by the Yellow River into the twin-shaft mixer, and then add water to mix and stir. 21% of the weight; use a vacuum mud machine to practice mud, and cut into mud ...

Abstract

The invention belongs to the technical field of building materials, and provides a method for preparing an environment-friendly ceramic plain brick by sediment of the Yellow River. The method is characterized by comprising the following: 1) a step of blank preparation, in which, the sediment of the Yellow River is dug up from riverbed, and is deposited for more than 10 years to be deposited sediment of the Yellow River; the blank comprises the following compositions in weight percentage: 60 to 80 percent of the deposited sediment of the Yellow River, 5 to 10 percent of pulverized fuel ash, 5 to 10 percent of coal refuse, 5 to 10 percent of fluxing agent, and 5 to 10 percent of grog refractory; the compositions are selected for standby; water is added to the mixture for mixing and stirring, wherein the amount of the water is 20 to 22 percent of gross weight of the deposited sediment of the Yellow River, the pulverized fuel ash, the coal refuse, the fluxing agent and the grog refractory; mud is milled by a vacuum pugmill, and is cut into mud cakes; after the mud cakes are aged for 3 days, the blank is produced for standby; 2) a step of glaze preparation; 3) a step of shaping; 4) a step of glazing; 5) a step of drying; and 6) a step of maturing, thereby producing the environment-friendly ceramic plain brick with water content ratio of between 6 and 8 weight percent. The plain brick prepared by the method has the characteristics of high regularity, high strength and strong decoration, and can be directly used for walls bricklaying without external decorating.

Description

technical field [0001] The invention belongs to the technical field of building materials, and particularly relates to a preparation method of ceramic clear water bricks. Background technique [0002] Ceramic facing brick is a sintered wall material that integrates decoration, heat preservation, load-bearing and other functions. Because the ceramic facing brick wall has the breathing function of absorbing and expelling moisture, it naturally adjusts humidity, temperature, and has thermal and sound insulation effects. it is good. People feel comfortable living in this environment. The buildings and landscapes built with ceramic clear water bricks have the characteristics of matte natural, elegant style, solemn and durable, beautiful and generous, and distinctive personality. It is generally believed that the regularity of ceramic clear water bricks is high (the error is within ±1mm), the water absorption rate is low (6-8%), and the compressive strength is high (above 30MPa)...
