Abstract
The invention relates to dry-mixed mortar for ground. The dry-mixed mortar for the ground comprises the following raw materials in part by weight: 18 to 28 parts of composite Portland cement 42.5, 66 to 76 parts of dry river sand, 5 to 8 parts of coal ash, 0.08 part of hydroxypropyl methyl cellulose ether, 0.3 part of calcium formate powder, 0.3 part of sodium naphthalene sulfonate and 0.2 part of lime powder. The dry-mixed mortar for the ground has the technical effects that: the raw materials of the mortar are mixed in advance to form the dry-mixed mortar, so the stirring time of the raw materials of the mortar is reduced and the construction efficiency is improved.
Description
Technical field
The present invention relates to a kind of mortar, relate in particular to a kind of ground and use dry-mix.
Background technology
When building a house, need use various building material, the mortar that uses in different occasions is exactly indispensable material of construction; The material of forming mortar must just need be transported to the place that builds a house respectively before building a house, manual work adds water stirring back formation mortar with cement and river sand then, and doing so not only influences operating efficiency; And cause construction ground dirty and messy; Particularly the cement tide of holding is rotten, influences cement quality easily, causes the building materials waste; And the each addition of the material in the mortar is different, and the mortar quality is unstable.
Summary of the invention
The object of the present invention is to provide a kind of ground to use dry-mix, the prior proportional mixing of material of construction guarantees that the quality of slurry is unified, and operating efficiency is provided.
The present invention realizes like this, comprises following raw materials in part by weight: 18-28 parts of 42.5 composite Portland cements, 66-76 parts of dry river sands, 5-8 parts in flyash, 0.08 part of hydroxypropyl methyl cellulose ether, 0.3 part in calcium formiate powder, 0.3 part of sodium naphthalene sulfonate polymer powder, 0.2 part of lime powder.During preparation, above-mentioned raw materials mixed get final product, during use mixed slurry is added suitable quantity of water and can form mortar.
Technique effect of the present invention is: the starting material of mortar are mixed the formation dry-mix in advance, and each component metering is accurate, and economical with materials avoids waste; The airborne dust that reduces or avoid building site stacking transportation of materials material to cause, it is convenient to construct, reliable in quality, the hollowing cracking phenomena after the product of avoiding common on-the-spot preparation mortar to occur is easily constructed; Factory's preparation, the sealing transportation, the scene adds water stirs, with following usefulness; Construction easily, and is of fine qualities, adds black talc; Workability improves, and outward appearance is level and smooth, and construction effect is good.
