Abstract
The invention relates to a dry powder mortar of stone dust, which is characterized in that the dry powder mortar of the stone dust is mainly formed by cement, fly ash, yellow sand, stone dust or mortar thickening powder. The invention initially takes the stone dust as the raw material of the dry powder mortar, and the mechanical property of the stone dust in the mortar is more excellent than the yellow sand, thereby changing waste into valuables. The invention is economical and environment-friendly.
Description
Technical field
The invention belongs to building material field, be specifically related to a kind of limestone powder dry powder mortar.
Background technology
Stone flour is that the stone quarry produces the waste that produces in the stone process, the stone flour that pile up like a mountain causes severe contamination to environment, and the meal content of stone flour is more, can have a negative impact to intensity and other performances so people without the raw material of stone flour as dry-mix, think.
Main in the past yellow ground and some the Additive Production dry-mix of adopting with regard to yellow ground, needs medium sand (fineness modulus 2.3～3.0), and because of building operation such as wet-mix concrete are in great demand to yellow ground, this just makes that medium sand is under-supply.
We are through trying to join, study, adjust mixing to the different volumes of same intensity grade and to different intensity grades sand, stone flour, and through secular effort, the qualified dry-mix of intensity is allotted in examination, and initiative is with the raw material of stone flour as dry-mix.
Summary of the invention
The objective of the invention is provides a kind of limestone powder dry powder mortar at above-mentioned weak point.
The objective of the invention is to implement in the following manner:
A kind of limestone powder dry powder mortar is characterized in that this limestone powder dry powder mortar mainly made by the raw material of the drying regime of following mass percent:
Cement 10～35%
Flyash 3～12%
Yellow ground 25～55%
Stone flour 25～55%
Mortar densification powder 1.3～5.2%.
Above-mentioned limestone powder dry powder mortar is characterized in that this dry-mix also can add following additive:
Account for above-mentioned limestone powder dry powder mortar weight 0.01～3.0% redispersable latex powder,
Account for above-mentioned limestone powder dry powder mortar weight 0.01～1.0% ether of cellulose,
Account for above-mentioned limestone powder dry powder mortar weight 0.01～1.0% fiber,
Account for above-mentioned limestone powder dry powder mortar weight 0.01～0.2% retardant,
Account for above-mentioned limestone powder dry powder mortar weight 0.01～1.0% water reducer,
With account for above-mentioned limestone powder dry powder mortar weight 0.01～4.0% hardening accelerator.
Percentage composition of the present invention is the quality percentage composition.
Above-mentioned ether of cellulose is methyl hydroxyethylcellulose ether or methylhydroxypropylcellulose ether; Above-mentioned fiber is synthon or wood fibre.
Above-mentioned retardant can be wooden calcium sulfonate or sodium phosphate etc.; Described water reducer can be calcium lignin sulphonate or trimeric cyanamide etc.; Described hardening accelerator can be calcium formiate or sodium sulfate etc.
Stone flour is the limestone crushing gained, and quality is hard, and sharp corners is arranged, and surface irregularity and cement-bonded property are good.The quality of stone flour depends on grating, and the stone flour voidage for preparing of level is little, and capacity is big, and density is good, and the present invention uses stone flour fineness modulus 2.7～3.0, and is preferred 2.9, grating two districts.The fineness modulus 2.7～3.0 of yellow ground, preferred 2.8, grating two districts.The mixture denseness is close, and the clean slurry that is used to wrap up fine aggregate is moderate, just can fill gap between fine aggregate.Yellow ground is close with the stone flour fineness modulus.No matter the two is by what mixed, and the compound grating that obtains is suitable with former grating.
" powder " content is bigger in the stone flour, cross the powder of 0.080mm sieve and can be regarded as " mud ", but " mud " in the stone flour is different with " mud " in the sand, and the former and grout cohesiveness are better.
We do through secular, a large amount of examination allotments of labor, mix stone flour in dry-mix, and the research stone flour is to the influence of mortar strength, and examination is joined the result and shown, mixes stone flour in the dry-mix and intensity is not had a negative impact.This proportioning is suitable for ordinary mortar, also is applicable to extraordinary mortar.To take by weighing various raw materials in proportion and mix, the water that adds total material weight about 1/5th stirs and can use.
Beneficial effect of the present invention:
Under the identical condition of workability, the mechanical property of stone flour is superior than yellow ground in the mortar.The price of stone flour is half of yellow ground on the market, uses stone flour, and we turn waste into wealth, and not only economy but also environmental protection can significantly improve economic benefit.
Embodiment
The various raw materials that embodiment 1～12 will take by weighing in proportion mix, and the water that adds total material weight about 1/5th stirs.
The yellow ground fineness modulus is 2.7～3.0, two district's medium sands.The stone flour fineness modulus is 2.7～3.0, grating two districts.
The result: the result who joins by the examination of 12 proportionings in table 1, the table 2 as can be seen, the stone flour consumption increases progressively, intensity effect is little.
The various raw materials that embodiment 13～18 will take by weighing in proportion mix, and the water that adds total material weight about 1/5th stirs.Used yellow ground fineness modulus 2.8, two district's medium sands.Stone flour fineness modulus 2.9, grating two districts.
The result: by the contrast of table 3, table 4, be that the ordinary mortar examination of one group of 6 different intensity grades is joined, sand, stone flour half-and-half mix with the benchmark mortar ratio.(also done these 6 strength grade benchmark examinations simultaneously and joined, promptly used cement, flyash, yellow ground, densification powder, intensity is qualified).
