Abstract
The invention discloses a kind of complex additives in common dry-mixed mortar, it is mixed by the raw material of following parts by weight: 50~60 parts of hydroxypropyl methyl cellulose ether, 3~5 parts of air entraining agent, 15~25 parts of sodium gluconate, 5~15 parts of dextrin, 8~15 parts of high performance water reducing agent of polyocarboxy acid, 5~10 parts of defoaming agent.Compounded additive of the present invention can simplify factory formula and production procedure, reduce quality control link, and be easier to disperse when the addition of compounded additive, be suitable for large-scale production.And compounded additive of the present invention is different from simple mixture, application is to mix several substances by certain usage ratio to add.Large-scale dry-mixed mortar can be rapidly applied to produce, the control link of production process and the complexity of formula are reduced, is conducive to the stability and quality of mortar, and reduce influence of the additive weighing error to mortar, its performance is stablized, and several single additives added in mortar can be replaced.
Description
Technical field
The present invention relates to the production and application field of construction material is related to, specifically provide a kind of for general dry-mixed mortar
Compositional type additive.
Background technique
Common dry-mixed mortar factory formula is by cement, coarse sand, fine sand, flyash, hydroxypropyl methyl cellulose ether, bleed
The composition such as agent, sodium gluconate, dextrin, high performance water reducing agent of polyocarboxy acid, defoaming agent.Wherein hydroxypropyl methyl cellulose ether, draw
The additional amounts such as gas agent, sodium gluconate, dextrin, high performance water reducing agent of polyocarboxy acid, defoaming agent are few, single component dosage 0.1% with
Under.Dosage is more in actual production process, and quantitative addition needs metering numbers more, and the quality of single additive needs stringent control, raw
Production process is complicated and changeable, is unfavorable for the stability of quality when large-scale production.

Its performance is relatively stable, is easy to control density, the water retention of mortar, improves mortar strength.
To achieve the above object, embodiment of the present invention are as follows: a kind of complex additive in common dry-mixed mortar,
It is characterized in that, being mixed by the raw material of following parts by weight: 50~60 parts of hydroxypropyl methyl cellulose ether, air entraining agent 3~5
Part, 15~25 parts of sodium gluconate, 5~15 parts of dextrin, 8~15 parts of high performance water reducing agent of polyocarboxy acid, 5~10 parts of defoaming agent.
Preferably, it is characterized in that, the complex additive in common dry-mixed mortar, by following parts by weight
Raw material is mixed: 58 parts of hydroxypropyl methyl cellulose ether, 5 parts of air entraining agent, and 20 parts of sodium gluconate, 10 parts of dextrin, polycarboxylic acids
5 parts of high-performance water reducing agent, 2 parts of defoaming agent.
Preferably, the dextrin is starch by heating, decompose and hydrolysis under acid or diastatic action
And the polymer generated.
Preferably, the defoaming agent is organic silicon defoamer.
Compounded additive of the present invention can simplify factory formula and production procedure, reduce quality control link, and multiple
It is easier to disperse when with the addition of formula additive, is highly suitable for producing on a large scale.Compounded additive of the present invention is different from simple
Mixture, application be by several substances by certain usage ratio mix add.Can rapidly it be applied to large-scale dry
Mortar production, reduces the control link of production process and the complexity of formula, is conducive to the stability and quality of mortar, and subtract
Few influence of the additive weighing error to mortar, performance are stablized, and several single additives added in mortar can be replaced.
