Description
Technical field
The invention belongs to building mortar fields, and in particular to a kind of to replace masonry mortar, plastering mortar and ground simultaneously
The three-in-one dry-mixed mortar of mortar.
Background technique
In the finishing of ordinary commercial housing, main mortar product is exactly masonry mortar, plastering mortar and ground mortar.?
In construction and decoration, while needing to build a wall using masonry mortar first, then using plastering mortar, masonry mortar, ground mortar
The plastering painting that metope is carried out with plastering mortar, finally in floor leveling, uses ground mortar.It is flat by a commercial house 100
Square rice calculates, and the total used in amounts of all mortars is wanted tens tons, when purchasing different mortars, for layman, had
Certain difficulty.It is also easy to because estimation is not allowed to cause the multiple waste of raw material, or scene occurs because mortar model confusion makes
Quality accident is caused with mistake.
The characteristics of three classes mortar, is different, and plastering mortar needs to have good water-retaining property, easily constructs, anti-sag does not crack, not empty
The features such as drum, shrinking percentage is small, freeze thawing resistance.Masonry mortar needs to have adhesion strength height, and structural strength is high, freeze thawing resistance.Floor sand
It is good with hardness high-wearing feature that slurry is needed, weather-proof anti-aging, does not crack, not hollowing, long service life.Mortar currently on the market
For reasons of cost, it is difficult to take into account these types of performance in the case where low cost.So three kinds of mortars are all separated currently on the market
It uses.
Summary of the invention
The present invention to solve the above problems, provide a kind of three-in-one dry-mixed mortar, can simultaneously instead of masonry mortar, smear
Lime and brick and ground mortar mitigate construction pressure, reduce cost.
A kind of three-in-one dry-mixed mortar, composed of the following components by mass percentage: Machine-made Sand 77.9%-81.4%,
Cement 12.3%, powder 6.2%-9.7%, surplus are additive, and the Machine-made Sand includes the Machine-made Sand of partial size 0mm-1.2mm
The Machine-made Sand 16% of 61.9%-65.4%, partial size 1.2mm-2.4mm.
Preferably, the Machine-made Sand is made of high-purity limestone crushing, sand fineness modulus control 2.4-2.5 it
Between, partial size 0.075mm powder containing quantity below is not more than 12%, and clay content is within 3%.
Preferably, the additive is hydroxypropyl methyl cellulose ether.
Preferably, the cement is P.042.5R ordinary portland cement.
Preferably, the powder is that the partial size 0.075mm or less generated in Machine-made Sand shattering process is not less than 80% powder
Material, fineness modulus are not more than 20%, need water ratio no more than 102%.
Compared with prior art, the invention has the following advantages:
Dry-mixed mortar performance that dry-mixed mortar of the invention matches while meeting masonry mortar, plastering mortar and ground
The all properties of mortar.It can be used simultaneously as above-mentioned three kinds of mortars.
(1) three-in-one dry-mixed mortar of the invention carries out live allotment without artificial screening, reduces finishing cost of labor；
(2) powder is during producing produced by large-scale dust catcher absorption, and fineness modulus is small, and water retention is excellent, anti-current
Extension performance is strong, largely reduces the waste of landing ash, more can guarantee because of cracking, hollowing phenomenon caused by water retention is low or sagging.
(3) Machine-made Sand has been used to substitute river sand on inventive formulation raw material, with the stone generated in Machine-made Sand manufacturing process
Powder substitutes flyash, reduces product cost in big degree；
(4) the stringent screening of the invention to Machine-made Sand partial size is Machine-made Sand gradation degree much higher than other products, simultaneously
Flyash is substituted using mountain flour completely.So be different from the configuration of other product number of mechanisms sand in the market, the present invention only with
A kind of additive " hydroxypropyl methyl cellulose ether " more ensures producing line while operability, workability do not decline
The stability of balance and mortar gradation and workability.And other dry-mixed mortars in the market improve construction using multiple additives
Property, workability substantially increase cost, and result in waste of resources phenomenon.The investment of additive excessive simultaneously is met in dry-mixed mortar
Sleep stirring after react during, every kind of additive can all influence the hydration reaction of cement, increase enterprise extra cost it
Outside, it more threatens to quality.
(5) Machine-made Sand of different-grain diameter particle is sieved by different sand storages using vibration screening machine in production technology, convenient in proportion
The gradation of free hold mortar, the gradation degree of reinforced mortar, high gradation make mortar strength big, in same cement additive amount
In the case of, this three-in-one mortar strength is much higher than river sand base mortar 30%.
Detailed description of the invention
(nothing)
Specific embodiment
A kind of three-in-one dry-mixed mortar, it is composed of the following components by mass percentage: Machine-made Sand 77.9-81.4%, water
Mud 12.3%, powder 6.2-9.7%, surplus are additive hydroxypropyl methyl cellulose ether, which includes partial size 0mm-
The Machine-made Sand 16% of the Machine-made Sand 61.9-65.4% of 1.2mm, partial size 1.2mm-2.4mm.Machine-made Sand is high-purity limestone crushing
It is made, sand fineness modulus controls between 2.4-2.5, and 0.075mm partial size powder containing quantity below is≤12%, clay content control
Within 3%.The gradation degree of different-grain diameter is high, and mortar particle is the non-diamond shape of polygon.Powder is to produce in Machine-made Sand shattering process
Raw partial size 0.075mm or less is more than or equal to 80% powder, and fineness modulus is not more than 20%, needs water ratio no more than 102%.Water
Mud is P.042.5R ordinary portland cement.
Three kinds of different cement mortar ratios are set forth below to be described in detail:
Keep the proportion of the Machine-made Sand of 1.2mm-2.4mm partial size, powder, cement and hydroxypropyl methyl cellulose ether constant,
Change the ratio of powder and 0-1.2mm partial size Machine-made Sand.The water conservation of this dry-mixed mortar is tested according to the regulation of JGJ/T70 respectively
Rate, setting time, 14d tensile bond strength, 28d shrinking percentage and frost resistance, according to appendix A " consistency in GB/T25181-2010
Loss late test method " pertinent regulations test 2 hours consistency loss lates of mortar of the present invention.Each performance is as follows:
Above table as it can be seen that 0mm-1.2mm particle size content in 61.9%-65.4% and powder ratio in 6.2%-9.7%
Between in the case where, the performance indicator of three-in-one dry-mixed mortar meets the requirement of three kinds of mortars.
The technological process of production is as follows:
(1) Machine-made Sand enters screening machine with elevator, broken Machine-made Sand is divided into three kinds of partial sizes after broken
Different sand storages are respectively enterd, three kinds of grain size specifications are respectively 0-1.2mm, 1.2-2.4mm, 2.4-4.8mm；(2) by 0-1.2mm's
Machine-made Sand, cement, powder and additive are respectively delivered to respective weigher and weigh according to regulation ratio；(3) after the completion of weighing,
Each material enters blender and quickly stirs, and first time mixing time is 1 point of half, then stands 3 minutes, again quickly
Stirring 10-30 seconds.
Since this formula uses the advanced Machine-made Sand matched, stringent to the proportion requirement of different-grain diameter Machine-made Sand, performance is better than
The dry-mixed mortar of common river sand production, cement consumption is few, at low cost, so the cost of three-in-one dry-mixed mortar will not be more dry than three kinds
Mortar is used alone high.
One embodiment of the present invention above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
Limitations on the scope of the patent of the present invention therefore cannot be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to guarantor of the invention
Protect range.
