Description
Technical field:
The invention belongs to building material technical fields, and in particular to a kind of loess solidifies the preparation method for hitting real brick.
Background technique:
In the Northwest that loess blazons, a large amount of slabstones of exploiting can damage western fragile ecological environment, loess
It is that the Northwest is with the longest history, most popular natural material, passes through loess brick and replace mortar flag stone and concrete hollow
Brick can lower the carrying capacity of environment of the Northwest.But it since earth building intensity is low, durability is poor, volume stability is poor, adds
Traditional sun-dried mud brick manufacture craft is coarse, leads to traditional adobe house poor seismic behavior.
Summary of the invention:
The technical problems to be solved by the present invention are: providing a kind of solidify with the loess being economical and environmentally friendly worth hits real brick
Preparation method.
In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions: reality is hit in a kind of solidification of loess
The preparation method of brick, includes the following steps,
S1,100 parts of loess for taking drying by mass fraction and crossing 2mm sieve；
S2,10~20 parts of flyash of addition and 10~15 parts of plant fiber are taken by mass fraction, and by flyash
It is added in 100 parts of loess with plant fiber；
S3, it will be stirred evenly in above-mentioned raw materials investment blender, mixing time 15min；
S4, alkali-activator and distilled water in step S3 gains by 10 parts~12 parts of mass fraction addition, distilled water
Content is using the optimum moisture content of loess as standard；
S5, it will be stirred evenly in step S4 gains investment blender, mixing time 10min；
S6, appropriate step S5 gains are taken to pour into shaper, Beat numbers.
After S7, molding, step S6 gains are demoulded, natural curing 28d in 20 DEG C of room temperature is placed in and gets product.
Preferably, the flyash in step S2 is the powder of 200~300 mesh.
Preferably, the plant fiber in step S2 is corn stalk fiber, wheat straw fiber, rice hull cellulose, straw
One of fiber is a variety of, and plant fiber is the powder of 40~60 mesh.
Preferably, the alkali-activator in step S4 is sodium silicate aqueous solution, the modulus of alkali-activator is not more than 3.2, alkali
Exciting agent is 20 ° of é~30 ° B B é.
Preferably, the square mould that the mold in step S6 is 120mm~240mm.
Preferably, the compactive effort of Beat numbers is 100kJ~210kJ in step S6.
Compared with prior art, usefulness of the present invention is: realizing the recycling of loess material and reduces carrying capacity of environment；
It gathers materials on the spot, is solidified using environment friendly curing agent, there is value economical and environmentally friendly, meet northwest China Canal in Loess Area ecology
Civilization construction requirement；The present invention is by Beat numbers and natural curing, non-burning brick semidry method compression moulding and height with tradition
It presses steam curing different, production cost can be reduced, it is energy saving；What waterglass alkali-activated carbonatite flyash generated has gelling performance
Calcium silicate hydrate gel, so that the contact area of skeleton particle increases, the hole between particle is gradually reduced, and skeleton particle is by point
Contact becomes face contact, coheres as a close spatial networks overall structure, soil strength is improved；Meanwhile plant
Fiber has low-density, high length-diameter ratio, and loess is made to become reinforced earth, strengthens the connection between particle, toughening enhancing.
