Under allow its intensity to be apparently higher than similar product.
The present invention can effectively adapt to various operating conditions, construction, and reasonable formula adjustment can be made for different conditions, is mentioned
The high water-retaining property of mortar, intensity, workability, have prevented spilling water phenomenon after mortar stirring.And reduce dry-mixed plastering mortar original
Material and production cost improve construction efficiency, reduce environmental pollution.
The additive that the present invention uses can make corresponding adjustment, cellulose ether for different operating condition and environment
Play the role of water-keeping thickening, the water-retaining property for increasing mortar does not allow it spilling water, lamination occur while guaranteeing that mortar will not be because
For dehydration is too fast and the phenomenon that crack, thixotropic lubricant, which plays, to be promoted mortar mobility but can guarantee that its is not stratified
Effect, water-reducing agent, which play the role of reduction amount of water under the premise of guaranteeing application property, prevents loss of strength.
Specific embodiment
The mass fraction of this dry-mixed terrace mortar each component is as follows, cement: 16-18%, mountain flour: 0-10%, 0-1.2mm
Machine-made Sand: the Machine-made Sand of 55%, 1.2-2.4mm: the Machine-made Sand of 5-15%, 2.4-4.75mm: 18%-28%, cellulose ether:
0.015-0.03%, thixotropic lubricant: 0.02%, water-reducing agent: 0.1%.Wherein the mountain flour in formula is Machine-made Sand crushing and screening
When the powder that generates, pass through dust collecting system and collect and Machine-made Sand production line.
Wherein the main gradation distribution of third gear Machine-made Sand is as follows:
Wherein, Machine-made Sand particle fraction, sieve pore partial size are respectively 4.75mm:0,2.4mm:(18 ± 2) %, 1.2mm:(15
± 2) %, 0.6mm:(12 ± 2) %, 0.3mm:(10 ± 2) %, 0.15mm:(8 ± 2) %, 0.075mm:7% ± 2%, sieve bottom
(30 ± 3) %.
We can see that the dosage section of a variety of materials changes greatly from cement mortar ratio, main cause has following several
Point: 1, the intensity model of Gao Liudong terrace mortar is different, and the intensity of mortar is mainly derived from the dosage and mortar of cement in mortar
Gradation.2, the gradation of mortar inevitably has fluctuation in process of production, needs to pass through when mortar fluctuation of aggregate graduation range is larger
The parameter of a variety of materials is adjusted to make mortar guarantee original gradation and then ensure that the quality of mortar is stablized.High fluidity terrace sand
The main grading limit and partial size of slurry act on (using Machine-made Sand as radix 1) as shown in the table:
Wherein the Machine-made Sand of 2.4mm is mainly used for improving intensity, and the Machine-made Sand of 1.2mm is mainly used for improving workability,
0.15mm-0.6mm Machine-made Sand mainly prevents lamination from occurring, and guarantees application property, uses feel smoothness, 0.075mm and following
Machine-made Sand mainly improves mortar workability, water retention.
It is especially needed be pointed out that in the present embodiment 0.6mm, 0.3mm in the Machine-made Sand of 0.15mm-0.6mm partial size,
The ratio of 0.15mm presses linear decrease, forms an extraordinary gradation relationship, under the ratio, product is in practice of construction process
In have very high workability.
The fluctuation of cellulose ether dosage is the main reason is that because water retention requirement difference of the different seasons to mortar, winter
The difference of the water retention of season and summer mortar is larger, is found through experiments that the water retention of mortar under 5-10 DEG C of winter of environment temperature reaches
It is both not in quality problems to 88% metope, and the water retention needs of mortar reach under 30-35 DEG C of summer high temperature of environment temperature
It could be guaranteed to 95% metope quality.
So cellulose ether dosage is adjusted according to temperature difference, use environment temperature is between 5-10 DEG C, cellulose
Ether dosage is the 0.015%-0.02% of total amount, and when use environment temperature is more than or equal to 30 DEG C, cellulose ether dosage is total amount
0.025%-0.03%.
It is as follows that existing terrace mortar performance data on the market is compared by taking model M15 as an example:
42.5 intensity ordinary portland cements: 16%, mountain flour: the Machine-made Sand of 0%, 0-1.2mm: 55%, 1.2-2.4mm
Machine-made Sand: the Machine-made Sand of 7.85%, 2.4~4.75mm: 21%, cellulose ether: 0.03%, thixotropic lubricant 0.02% subtracts
Aqua 0.1%.
Above data is amount of water 15.8%, mixing time 60 seconds, is carried out under code test environment.
It can be seen that high fluidity terrace mortar has better mobility to make mortar in use process from above data
In be easier to construct, reduce the labor intensity of worker, improve construction efficiency, shorter setting time reaction mortar after construction before
Phase intensity can be formed quickly, so as to shorten the latent period of subsequent processing, while mortar gradation to be mutually filled in cost basic
Its intensity is allowed to be apparently higher than similar product in identical situation.
