Abstract

The invention discloses a loess baking-free brick which comprises the following raw materials in percentage by weight: 80-90 percent of loess, 6-14 percent of lime and 3-8 percent of gypsum. The invention also discloses a baking-free preparation method of the loess baking-free brick. As the loess baking-free brick is produced on the spot by adjusting measures to local conditions, using local materials and utilizing materials around a building site, the transportation cost of raw materials and products is greatly reduced, the cost of the braking-free brick is greatly reduced and a large amount of expenses can be saved for a town builder. In addition, the produced baking-free brick is MU10-MU20 in strength.

Description

Loess is non-burning brick and preparation method thereof

Technical field

The present invention relates to building material technical field, especially a kind of loess is non-burning brick, and preparation method thereof.

Background technology

Many as the building wall material category, traditional have sintered clay blue bricks, a sintered clay common brick, relatively is widely used on buildings and structures body of wall always.It is mainly to be various concrete hollow blocks and the solid concrete building block that consolidating material is made by cement that free of calcining and steam curing two exempt from brick; The unburned brick of singly exempting from is mainly to utilize the industrial waste coal ash for manufacturing to make solid brick and aerating foamed building block.Economically, all single, double to exempt from the brick price all expensive than sintered clay brick.Wherein the freight charges of brick and terminal charges account for 50% price.Along with the progress of society, accelerated the process that villages and small towns are built, the consumption of materials for wall is also increasing, and the dynamics of environment protection is also increasing, and it is also more and more tighter that system is dug in the production of sintered clay brick, from the perspective of policy, can substantially abolish the agglomerated powder cob brick soon.

Summary of the invention

The present invention is directed to the deficiencies in the prior art, propose a kind of loess non-burning brick, adopting bare place purposes loess to replace clay is raw material, has protected arable land purposes edatope.

Also proposed the non-burning brick preparation method of above-mentioned loess, do not adopted sintering processing, saved the energy, and the non-burning brick intensity of the loess that obtains is high.

In order to realize foregoing invention the first purpose, the invention provides following technical scheme: a kind of loess is non-burning brick, comprises the raw material of following weight content:

Loess 80%～90%

Lime 6%～14%

Gypsum 3%～8%.

Further, the weight content of each raw material is:

Loess 85%

Lime 10%

Gypsum 5%.

Further, contain the broken rubbish of the building that accounts for loess gross weight 10%～30% or rock ballast in described corpus luteum.

Compared with prior art, product of the present invention has the following advantages: suit measures to local conditions, gather materials on the spot, material around application and construction ground is filled a prescription on the spot, make on the spot and produce, greatly reduced the expense of starting material and Product transport, simultaneously also greatly reduced non-burning brick cost, can be the villages and small towns builder and save a large amount of expenses.And make the intensity of brick between MU10～MU20.

In order to realize foregoing invention the second purpose, the invention provides following technical scheme: the non-burning brick preparation method of a kind of loess as mentioned above comprises the following steps:

1. take raw material by following weight content:

Loess 80%～90%

Lime 6%～14%

Gypsum 3%～8%;

2. with above three kinds of raw material mix and blend 5～10min, put into the bricks die compacting after stirring and made its moulding in 2～5 seconds, then get final product to get finished product after the vapor cure 48～72hr with 80～160 ℃ of temperature.

Further, described vapor cure be mould brick be placed on relative humidity more than 90%, more than 80 ℃ in the saturated steam of temperature.

The present invention adopts physical method that admixtion is pressurizeed and the vapor cure mode is made, and need not sintering.

Embodiment

Describe the present invention below in conjunction with embodiment, the description of this part is only exemplary and explanatory, should any restriction not arranged to protection scope of the present invention.

Embodiment 1

A kind of loess is non-burning brick, comprises the raw material of following weight content:

Loess 85%

Lime 10%

Gypsum 5%.

Wherein, loess can be the mud shape; Contain the broken rubbish of the building that accounts for loess gross weight 10% in this corpus luteum.

With above three kinds of raw material mix and blend 5min, put into the bricks die compacting after stirring and made its moulding in 2 seconds, then get final product to get finished product after the vapor cure 48hr with 80 ℃ of temperature.Wherein vapor cure be mould brick be placed on relative humidity more than 90%, more than 80 ℃ in the saturated steam of temperature.

Embodiment 2

Loess 83%

Lime 14%

Gypsum 3%.

Wherein, contain the rock ballast that accounts for loess gross weight 30% in loess.

The preparation method is with embodiment 1.

Embodiment 3

Loess 86%

Lime 6%

Gypsum 8%.

Wherein, the broken rubbish of building that contains the rock ballast that accounts for loess gross weight 10% and 10% in loess.

The preparation method is with embodiment 1.

Non-burning brick with above-mentioned all embodiment, making size is 240 * 115 * 55mm, tests their intensity, is respectively: embodiment 1 is MU18, and embodiment 2 is MU15, and embodiment 3 is MU12.

Above-described embodiment baking-free brick material can be adopted the different different products of die production, can be brick, can be also that a watt fire other products.

In the face of villages and small towns construction brick, the at present production of materials for wall be all production unit be fix and product flows, the advantage that the present invention also has is: production unit be flow and product is fixed, it is to suit measures to local conditions, gather materials on the spot, material around application and construction ground is filled a prescription on the spot, makes on the spot and produces, and has greatly reduced the expense of starting material and Product transport, simultaneously also greatly reduced non-burning brick cost, can be the villages and small towns builder and save a large amount of expenses.
