Abstract

A kind of hards mixing mortar, mix by lime mortar and hards, wherein hards is for peeling off flax the hards fiber that the waste of flax behind the numb skin is processed into, the long 3-20mm of hards fiber, diameter are about 1mm, the hards fiber mixes in the mortar after softening, its in hards mixing mortar shared volume ratio for being no more than 40-50%; Hards mixing mortar weight after solidification of the present invention is light, and tensile strength increases, and is difficult for chapping, and thermal and insulating performance is good, and cheap.

Description

Hards mixing mortar and processing method thereof

Technical field

The present invention relates to a kind of hards mixing mortar, this hards mixing mortar intensity height, cost is low, and warmth retention property is good, is a kind of New Building Materials.

Background technology

Existing building is big with raw material cement mortar weight after solidification, and tension is not easily chapped, and intensity is low.And traditional cement mortar delamination degree, degree of sinking to, intensity, indexs such as freeze thawing resistance circulation are all lower, and water wasting mud takes sand, the cost height.

Simultaneously, flax is one of China's main farm produce, and the Heilongjiang Province accounts for 85% of national cultivated area, is main flax place of production.Wherein, numb skin is carried out utilization as the textile industry raw material, is piled up discardedly and peel off waste of flax behind the numb skin, does not only obtain reasonable use, simultaneously because it is not perishable, causes environmental pollution easily.

When seeking the solution of above-mentioned two problems at the same time, through many times experiment for many years, obtain a kind of hards mixing mortar, it has also solved the waste of flax in the agricultural and has handled problems in the performance that improves existing mortar.

Summary of the invention

Above-mentioned purpose is accomplished by following technical scheme:

A kind of hards mixing mortar, mix by lime mortar and hards, it is characterized in that: described hards is for peeling off flax the hards fiber that the waste of flax behind the numb skin is processed into, the long 3-20mm of described hards fiber, diameter are about 1mm, described hards fiber mixes in the mortar after softening, its in hards mixing mortar shared volume ratio for being no more than 40-50%;

Wherein, described mortar is mixed by cement, lime, sand, water, and each components by weight is a cement in the hards mixing mortar: lime: sand: hards=1: 1: 1-2: 3-4.Described hards mixing mortar and processing method thereof may further comprise the steps:

A, flax is peeled off waste of flax behind the numb skin make hards fiber about long 3-20mm, diameter 1mm, and soften;

B, with cement, lime, sand, hards by 1: 1: the weight ratio of 1-2: 3-4 is mixed, and adds water, makes hards mixing mortar, wherein, hards in hards mixing mortar shared volume ratio for being no more than 40-50%.

Hards described in the present invention is for after peeling off numb skin with flax, the hards fiber that is processed into waste of flax.The hards fibre property is good, its tensile strength height, and not perishable, light weight is easy to get, cost is low, mixes in the mixed mortar, can improve the crack resistance of mortar greatly, reduces coat of plaster weight, improve the house insulation heat-proof quality, reduce the consumption of cement and sand, thereby reduce housing cost.Evidence, the other plant rhizome, for example the fibroid of cornstalk etc. is poor, and tensile strength is low, can not satisfy the technical requirement of motar.

Technical scheme of the present invention has following beneficial effect:

1. experiment showed, that the indexs such as delamination degree, degree of sinking to, intensity, freeze thawing resistance circulation of hards mixing mortar all satisfy the requirement of motar, slightly higher than traditional cement mortar.

2. this product bulk density is 64.7% of a common mixed mortar, has reduced the coat of plaster deadweight;

3. the thermal conductivity factor of hards mixing mortar is much smaller than common mixed mortar, and the thermal and insulating performance of the coat of plaster behind the 50mm is equivalent to the brick wall behind the 90mm, becomes a kind of light-weight thermal-insulation wall raw material.

4. hards mixing mortar can be used cement 32.1% for every cubic metre less, uses sand 54.4% less, can reduce coat of plaster cost 29.53%, and only the Heilongjiang Province in architectural engineering is plastered, can save 80,000,000 yuan of building costs to annual flax waste bar development and use every year.

5. the hards cement mortar can also be improved the insulation in house, sound absorption qualities, and the crack resistance of raising coat of plaster improves wall quality, reduces construction costs.

6. undergraduate course is ground into fruit and can widelys popularize in the township enterprise in flax place of production, has broad application prospects and obtains remarkable economic efficiency.Raw material flax waste of flax is agricultural byproducts, and output is big, and it is wide to distribute, and can gather materials on the spot, and turns waste into wealth.Its resource is inexhaustible.

7. the tow scutcher tool can adopt general pulverizer, need not special process equipment, and production process is simple, and once less input.Need not special factory building.The process less energy consumption, pollution-free, and pile up the contaminated environment of going rotten for waste of flax and find solution route.

8. hards processing can be located at flax place of production, be processed into fiber after, packed each job site of selling to.To the hards processing space, agricultural byproducts are become commodity can obtain economic benefit.To applying unit, saved cement and yellow ground, reduced the coat of plaster cost, also can obtain considerable economic, can think that this scientific and technological achievement has broad application prospects.

The specific embodiment

Embodiment 1:

Hards mixing mortar, its composition comprises: cement mortar, be mixed with hards in the described cement mortar, ratio of weight and number wherein is a cement: lime: sand: hards=1: 1: 1-2: 3-4 mixes.

Described hards cement mortar and processing method thereof are:

A, flax is peeled off waste of flax behind the numb skin make hards fiber about long 3-20mm, diameter 1mm, and soften;

B, with cement, lime, sand, hards by 1: 1: the weight ratio of 1-2: 3-4 is mixed, and adds water, makes hards mixing mortar, wherein, hards in hards mixing mortar shared volume ratio for being no more than 40-50%.

Wherein, described hards mixing mortar can be widely used in wall plastering and build by laying bricks or stones.

For those of ordinary skills; be easy to expect on the application's basis; the ratio of described hards mixing mortar, constituent etc. are changed or suitable adjustment a little; but and and incomplete same similar products like, this product that obtains is also within the scope that the application's claim is asked for protection.
