Problems solved by technology

The cost of this treatment method is high and it also pollutes the environment. Moreover, for the residual slurry of the pipe pile itself, no matter how it is discarded, it is a waste of resources.

Embodiment 1

[0024] A method for producing concrete solid bricks by using pipe pile residual slurry, comprising the following steps:

[0025] (1) Material preparation: Collect the residual slurry of pipe piles from the production workshop of pipe piles and transport them to the production workshop of concrete bricks, remove the large aggregate in the residual slurry of pipe piles, prepare aggregates and fly ash at the same time, and measure them according to the following weight ratio For later use: pipe pile residual slurry 15%, aggregate 80%, fly ash 5%; among them, the aggregate is crushed stone chips, the maximum particle size is less than or equal to 15mm, and the aggregate particle size is less than 0.15mm The content is less than or equal to 20% of the whole aggregate.

[0026] (2) Stirring of raw materials: The prepared raw materials are operated in the order of aggregate first and then fly ash. First, dry mix for 30 seconds, and then add the residual slurry of pipe piles for stirr...

Embodiment 2

[0037]A method for producing concrete porous bricks by using pipe pile residual slurry, wherein the maximum particle size of the aggregate is less than or equal to 2 / 3 of the minimum rib thickness of the porous concrete bricks, and the pressing pressure during the pressing process is controlled to 15Mpa, and the forming The time is controlled at 20 seconds, and its stacking height is 4-6 boards when resting indoors. The remaining parts are the same as those in Embodiment 1, and will not be repeated here.

Abstract

The invention discloses a method for producing a concrete brick by using residual slurry of a tubular pile, and belongs to the manufacturing field of building materials. The method comprises the steps of material preparation, raw material stirring, brick pressing, indoor standing, water-holding curing and product formation. The invention discloses a method for simply determining a matching ratio by simply evaluating effective ingredients of the residual slurry of the tubular pile. Compared with the prior art, the method is simple and practical; the residual slurry of the tubular pile, originally serving as waste, is used as the raw material, and the concrete brick meets various standards related with national buildings, so the treatment expense of a tubular pile production enterprise on the residual slurry of the tubular pile is saved, and the pollution of the residual slurry of the tubular pile to the environment is avoided; and on the other hand, the residual slurry of the tubular pile substitutes cement and is used as a cementing material for making bricks, so the production cost of a concrete brick production enterprise is reduced.

Description

technical field [0001] The invention relates to a manufacturing method of building materials, in particular to a method for producing concrete bricks by utilizing the residual slurry of pipe piles. Background technique [0002] On the one hand, with the increasing number of industrial and civil buildings, because clay red bricks need to consume a lot of clay, firing red bricks will destroy a lot of cultivated land, therefore, the state regulations no longer allow the use of clay fired bricks. Brick enterprises use various raw materials to fire bricks, among which cement concrete bricks are more common. For example, the Chinese invention patent with application number 200810136858.5 discloses a concrete solid brick of crushed stone, which is composed of the following materials in mass percentage: 50-70% of crushed stone, 20-40% of fly ash , 3-10% quicklime, 2-5% cement, 0.5-2% admixture; after mixing the above materials, add an appropriate amount of water and stir, and use a...
