Abstract

A non-burning light-weight brick is made up of sand as main raw material, expanded pearlite powder, lime, powdered coal ash, silicon slag and cement through shaping, and high-temp high-pressure steam curing, and features widely available raw materials, light weight, high strength and small allowable tolerance.

Description

A kind of light sand-lime bricks and production method thereof
The invention belongs to method non-burning brick and preparation, particularly is not light sand-lime bricks of raw material and preparation method thereof with the clay.
Existing construction material is a raw material by clay, cinder (ash), stone, mine tailing, metallurgical waste etc. mainly, the making of this class wall body brick need consume a large amount of clays, occupy cultivated land, make and originally nibbled day by day and reduce, so country has not encouraged to produce this brick with regard to arable land seldom.For addressing this problem, many producers and research institution have developed and have not contained or few building brick argillaceous, as Haydite bricks, structural clay tile, hollow clinker brick, diatomite brick etc., report is also arranged, in Chinese patent literature as CN1037886A, CN1051543A, CN1115310A etc.The subject matter that these new shaped bricks exist is, cost is higher relatively, and is conflicting between unit weight and intensity, and then intensity is lower even will to satisfy lightweight; If want the intensity height then to be difficult to reach lightweight.
The purpose of this invention is to provide a kind of light sand-lime bricks and production method thereof, it does not use clay, and cost is lower, and existing lighter unit weight has higher intensity again.
It is major ingredient that the present invention is achieved in that with sand, allocates swelling perlite powder, lime, flyash, white residue and cement into, be pressed into adobe after, putting into the steam-cured unit weight that forms of autoclave High Temperature High Pressure is 800～1000Kg/m 3Light sand-lime bricks.
The weight percent that constitutes the various compositions of light sand-lime bricks of the present invention is sand 40～55%, lime 10～15%, swelling perlite powder 15～20%, cement 3～8%, flyash 10～20%, white residue 6～15%.Each raw material need be made fermentative processing after mixing, make the quality of product better.In steaming the process of pressing, working conditions preferably is controlled at, 170～200 ℃ of temperature, vapor pressure 8～10Kg/cm 2, steam 4～5 hours pressure time, curing time 5～8 hours.Among getting the raw materials ready, an amount of diatomite or vermiculite can be added, in the composition of brick with the body of wall that satisfies some particular technology requirements brick needs.When using sand, the most cheap with mountain sand, then effect is best to adopt quartz sand.
Below, according to several specific embodiments of the present invention, its technical scheme is being described in further detail.
Embodiment 1
At first get the raw materials ready by following weight percent, sand 55%, lime 10%, swelling perlite powder 15%, cement 3%, flyash 11%, white residue 6%, adding water then stirs, fermented again 30 minutes～1 hour, be pressed into the adobe of 240 * 115 * 53mm or 240 * 115 * 106mm with brick pressing machine, send into to steam in the autoclave and press, temperature is 170 ℃, vapor pressure 10Kg/cm 2, steam 5 hours pressure time, curing time 8 hours, making unit weight is 920Kg/m 3Finished bricks, ultimate compression strength can reach more than the 8MPa.
Embodiment 2
At first get the raw materials ready according to following weight percent, sand 48%, lime 12%, swelling perlite powder 17%, cement 3%, flyash 12%, white residue 8%, adding water then stirs, fermented again 30 minutes～1 hour, be pressed into the adobe of 240 * 115 * 53mm or 240 * 115 * 106mm with brick pressing machine, send into to steam in the autoclave and press, temperature is 190 ℃, vapor pressure 9Kg/cm 2, steam 4.5 hours pressure time, curing time 7 hours, making unit weight is 840Kg/m 3Finished bricks, ultimate compression strength can reach more than the 8MPa.
Embodiment 3
At first by looking for following weight percent to get the raw materials ready, sand 40%, lime 15%, swelling perlite powder 20%, cement 3%, flyash 10%, white residue 12%, adding water then stirs, fermented again 30 minutes～1 hour, be pressed into the adobe of 240 * 115 * 53mm or 240 * 115 * 106mm with brick pressing machine, send into to steam in the autoclave and press, temperature is 200 ℃, vapor pressure 8Kg/cm 2, steam 5 hours pressure time, curing time 5 hours, making unit weight is 800Kg/m 3Finished bricks, ultimate compression strength can reach more than the 8MPa.
Technique scheme of the present invention can reach following effect:
1, do not use clay fully;
2, unit weight is lighter, can be lower than 800Kg/m3；
3, every index meets national standard;
4, intensity is higher, can reach 8～10MPa;
5, price is lower, is suitable as the Highrise buildings materials for wall.
