Abstract
The invention discloses a building mortar admixture which includes following components, by weight, 80-100 parts of a naphthalene sulfonic acid/formaldehyde, 140-180 parts of molasses calcium, 25-30 parts of methyl cellulose ether, 20-32 parts of sodium dodecyl benzene sulfonate, 80-100 parts of mineral powder and 40-80 parts of bentonite. The raw materials are added successively into a reactor in order and then are subjected to mechanical stirring and mixing to obtain the admixture. The admixture is used for masonry mortar, plastering mortar and decorative mortar, can reduce usage amount of water and cement in the mortar, can improve strength and durability, can reduce the use quantity of cement, can reduce shrinkage rate and cracking damage.
Description
Technical field
The present invention relates to a kind of additive for building mortar.
Background technology
Additive for building mortar mixes in the process of mixing building mortar, in order to improve the material of building mortar performance.Admixture can improve the performance of building mortar effectively, and has good economic benefit, becomes material indispensable in building mortar.
Summary of the invention
The object of this invention is to provide a kind of additive for building mortar, this admixture is used for masonry mortar, motar and decoration mortar, contribute to after mixing reducing mortar water consumption and cement consumption, improve intensity and weather resistance, reduce cement consumption, shrinking percentage, cracking harm.
Object of the present invention is achieved through the following technical solutions:
A kind of additive for building mortar, is characterized in that: this admixture composition and weight part ratio are: naphthalene sulfonic acidformaldehyde condensation product 80-100 part, sugared calcium 140-180 part, methyl cellulose ether 25-30 part, Sodium dodecylbenzene sulfonate 20-32 part, breeze 80-100 part, wilkinite 40-80 part.
Further, this admixture composition and weight part ratio are: naphthalene sulfonic acidformaldehyde condensation product 80 parts, sugared calcium 140 parts, methyl cellulose ether 30 parts, Sodium dodecylbenzene sulfonate 20 parts, breeze 100 parts, wilkinite 40 parts.
Or further, this admixture composition and weight part ratio are: naphthalene sulfonic acidformaldehyde condensation product 100 parts, sugared calcium 180 parts, methyl cellulose ether 25 parts, Sodium dodecylbenzene sulfonate 32 parts, breeze 90 parts, wilkinite 60 parts.
This admixture raw material adds in reactor in order successively, and mechanical stirring mixes, and can obtain.
The effect of each component of following brief description: naphthalene sulfonic acidformaldehyde condensation product: the consumption reducing mortar and cement, extends the time of coagulation of mortar.Methyl cellulose ether: increase viscosity, prevent layering and segregation.Sodium dodecylbenzene sulfonate: bleed, improves the workability of mortar, freeze-thaw-cyclicity.
The present invention is used for masonry mortar, motar and decoration mortar, contributes to reducing mortar water consumption and cement consumption after mixing, and improves intensity and weather resistance, reduces cement consumption, shrinking percentage, cracking harm.
Present invention process is simple, and applied widely, addition means is easily grasped, environmentally safe, utilization of waste material; Product performance are excellent, improve the ultimate compression strength of mortar, water-retentivity and freeze-thaw-cyclicity, improve construction quality.
