Embodiment 1

[0026] Utilize the method that Yellow River silt is prepared environment-friendly ceramic clear-water brick, it comprises the steps:

[0027] 1) Billet preparation: excavate the Yellow River silt from the Binzhou section of Shandong Province from the river bed, and pile it up by the river for 15 years to become the Yellow River sediment (fully weathered); The sand is dried on the chain plate dryer until the moisture content is below 5wt% (weight); the gangue and the flux are respectively crushed to 1mm with a jaw crusher, and the clinker is crushed to 1mm, and set aside;

[0028] Percentage by weight: Yellow River sediment 60%, fly ash 10%, coal gangue 10%, flux 10%, clinker 10%; select the Yellow River sediment, fly ash, coal gangue, flux and cooked material, spare;

[0029] Add the Yellow River sediment, fly ash, coal gangue, flux and clinker into the twin-shaft mixer and add water to mix and stir. The amount of water added is the total amount of the Yellow River sediment, ...

Embodiment 2

[0038] Utilize the method that Yellow River silt is prepared environment-friendly ceramic clear-water brick, it comprises the steps:

[0039] 1) Billet preparation: excavate the Yellow River silt from the river bed in Dong'a section of Shandong Province, and pile it up by the river for 12 years to become the Yellow River sediment (fully weathered); The sand is dried on the chain plate dryer until the water content is below 5wt% (weight); the gangue and the flux are respectively crushed to below 1mm with a double-roller crusher, and the clinker is crushed to 1.5mm, and set aside;

[0040] Percentage by weight: Yellow River sediment 80%, fly ash 5%, coal gangue 5%, flux 5%, clinker 5%; select the Yellow River sediment, fly ash, coal gangue, flux and cooked material, spare;

[0041] Add the Yellow River sediment, fly ash, coal gangue, flux and clinker into the twin-shaft mixer and add water to mix and stir. The amount of water added is the total amount of the Yellow River sedime...

Embodiment 3

[0050] Utilize the method that Yellow River silt is prepared environment-friendly ceramic clear-water brick, it comprises the steps:

[0051] 1) Blank preparation: the Yellow River silt is dug out from the river bed, and it is stacked by the river for 20 years to become the Yellow River sediment (fully weathered); then the Yellow River sediment is dried on a chain plate dryer to a moisture content of 4wt% ( weight); use a jaw crusher to crush the gangue and flux to 0.8mm respectively, and crush the clinker to 1mm for later use;

[0052] Percentage by weight: Yellow River sediment 70%, fly ash 8%, coal gangue 8%, flux 7%, clinker 7%; select the Yellow River sediment, fly ash, coal gangue, flux and cooked material, spare;

[0053] Add the Yellow River sediment, fly ash, coal gangue, flux and clinker into the twin-shaft mixer and add water to mix and stir. The amount of water added is the total amount of the Yellow River sediment, fly ash, coal gangue, flux and clinker. 21% of ...

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 in particular 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 moisture absorption and moisture discharge, it can naturally adjust humidity and temperature, and has the effect of heat insulation and sound insulation. it is good. People feel comfortable living in this environment. The buildings and landscapes made of ceramic clear water bricks have the characteristics of matte nature, elegant style, solemn and durable, beautiful and generous, and distinctive personality. It is generally believed that ceramic clear water bricks have high regularity (within the error of ±1mm), low water absorption (6-8%), and high compressive strength (above 30M...
