Abstract

The present invention relates to method of making construction material using yellow phosphorus waste slag, the yellow phosphosus waste slag is ground into powder, blending according to phosphorus, cement:lime:soot powder as 5:0.5:0.2:0.2, add water and mix, press into standard brick, the sand dust is prepared by blending according to phosphorus slag:cement:lime:clag as 7:0.3:0.4:0.85, the construction material made according to present invention is high in press strength, heat insulating, low in production cost, and can protect environment.

Description

Utilize the method for yellow phosphorus sludge to produce building material

The present invention relates to the making method of standard brick and dust and sand, particularly a kind of method of utilizing yellow phosphorus sludge to produce building material.

Standard brick is to make with stone sand and cement in the prior art, and dust and sand is to make with silt, lime and cement, its manufacturing cost height, insulation, heat insulation poor.

The objective of the invention is to: a kind of method of utilizing yellow phosphorus sludge to produce building material is provided, a large amount of yellow phosphorus waste slags can be recycled, reach the purpose of protection environment, utilization of waste material with this method.

Formation of the present invention: the proportioning raw materials that (1) makes the standard brick material of construction is: phosphorus slag 5: cement 0.5: lime 0.2: cigarette ash powder 0.2: water 0.5;

(2) proportioning raw materials of making dust and sand material of construction is: phosphorus slag 7: cement 0.3: lime 0.4: clay 0.85;

According to above proportioning raw materials (1), yellow phosphorus waste slag is ground into 20% powdery, add cement, lime, cigarette ash powder and water and stir, mechanical pressing through check, maintenance, is made standard brick;

According to above proportioning raw materials (2), yellow phosphorus waste slag is ground into 20% powdery, add cement, lime, be stained with stirring, metering, packing.

Compared with the prior art, the present invention can utilize yellow phosphorus sludge to produce building material in a large number, the material compressive strength height of its making, and insulation, heat insulation good, low cost of manufacture can reduce the floor space of yellow phosphorus waste slag with utilization of waste material, the protection environment.Because its compressive strength height also can be made material of construction such as porous Hollow brick.

Embodiments of the invention 1: yellow phosphorus waste slag is ground into 20% powdery, again in phosphorus slag 5: cement 0.5: lime 0.2: the ratio batching of cigarette ash 0.2, add water and stir, machine is pressed into standard brick.

Example 2: yellow phosphorus waste slag is ground into 20% powdery, and again in phosphorus slag 7: cement 0.3: lime 0.4: the ratio batching of clay 0.85 stirs into dust and sand.

Claims (1)

1, a kind of method of utilizing yellow phosphorus sludge to produce building material is characterized in that: the proportioning raw materials that (1) makes the standard brick material of construction is: phosphorus slag 5: cement 0.5: lime 0.2: cigarette ash powder 0.2: water 0.5;

(2) proportioning raw materials of making dust and sand material of construction is: phosphorus slag 7: cement 0.3: lime 0.4: clay 0.85;

According to above proportioning raw materials (1), yellow phosphorus waste slag is ground into 20% powdery, add cement, lime, cigarette ash powder and water and stir, mechanical pressing through check, maintenance, is made standard brick;

According to above proportioning raw materials (2), yellow phosphorus waste slag is ground into 20% powdery, add cement, lime, clay stirring, metering, packing.
