Abstract

The invention relates to a manufacturing method of light pavement bricks with high intensity and high water permeability. The manufacturing method comprises the following steps: preparing mixtures; molding the pavement bricks; drying; setting and roasting. The manufacturing method has sufficient raw materials, can effectively purify the environment and reduce pollution sources, can quickly absorb accumulated water of brick surfaces, saves external roasting energy consumption, is more firmly combined with bedding mortar in a construction process and is not easy to loosen; and the roasted bricks have lighter weight.

Description

The making method of light high-intensity water permeability pavement bricks

Technical field

The present invention relates to a kind of brick-making method, especially utilize river lakebed mud and domestic sludge to be raw material, improve the traditional product shape, sintering is made the making method of lightweight, high-strength, high permeability performance pavement bricks.

Background technology

Traditional pavement bricks (being commonly called as the bread brick) is to be that raw material mixes compacting and forms with cement, aggregate chips, flyash, and is heavy, water-absorbent is poor, and combines insecure (loosening easily) with the bed course mortar;

Summary of the invention

The objective of the invention is to overcome the deficiencies in the prior art, a kind of raw material abundance, environment purification are provided, make the source of pollution minimizing, can absorb rapidly the brick surface ponding, combine more firmly, be difficult for loosening, weight when saving outside roasting energy consumption, construction with bedding mortar than the light making method of pavement bricks.

According to technical scheme provided by the invention, described light high-intensity water permeability pavement bricks making method comprises the steps:

Compound preparation: it is to prepare by weight after 0% that mud mud cake, slag and lake, river mummification bed mud all are converted to water ratio, during preparation, the amount that adds mud cake in per two weight part slags is 1～3 weight part, the amount that adds lake, river mummification bed mud is 5～7 weight parts, wherein the slag particle diameter is less than or equal to 2mm, mix back 1～2 week of ageing, measure the compound water ratio and reach 8～16%, be used to make the adobe material;

The road stock mould is pressed: fix fin on die bottom plate, add pug in mold cavity, use the formula road brick press that jolt-squeezes that pug is carried out pressing mold, the power of impulsing of the formula of jolt-squeezing road brick press is controlled at 40～68KN, vibration frequency is controlled at 4000～5000 times/minute, and amplitude is controlled at 10～15mm;

Dry: as adobe material in road to be adopted natural air drying or the dry cage dual mode of waste heat, adobe material water ratio is reduced to be less than or equal to 7%;

Setting: with the staggered lapping of dried road adobe material, and leave 5～10mm gap in stoving oven, make airstream in kiln unimpeded, base substrate can fully be heated;

Roasting: stoving oven carries out roasting behind setting, and firing temperature is at 1080～1150 ℃ in the control stoving oven, and firing period was controlled at 13～19 hours.

The present invention has following advantage:

1, the selection of raw material all is to utilize life or trade wastes such as river lakebed mud, domestic sludge and slag, and the raw material abundance can make the source of pollution minimizing again.

2, adobe is after roasting, and the remaining coal in organic matter in the domestic sludge and the slag divides fully burning, makes finished product inside be full of abundant fine pore, can absorb the ponding on brick surface rapidly, has and can save outside roasting energy consumption.

3,, increased contact area and the bonding force of finished product bottom with bedding mortar by changing the bottom shape of finished product.Owing to increased indent, then the bottom contact area has increased about 50%, and during laying, because bedding mortar is filled to interior recess, both have formed mutual occlusion structure to solidify the back, and it is more firm that novel road brick is combined with bedding mortar, is difficult for loosening.

4, after the remaining coal in organic matter in the domestic sludge and the slag divides fully burning, finished product unit's unit weight diminishes, the change of novel road brick bottom shape, reduced the consumption of raw material again, make that brick list brick weight ratio tradition road, novel road brick is light more than 40%, both make things convenient for transportation, alleviated construction labour intensity again.
