Abstract

Dry-mixed waterproof mortar is characterized by comprising the following ingredients (by weight): 45-60% of limestone machine-made sand, 20-30% of yellow sand, 3-10% of fly ash, 12-18.3% of cement and 1.2-1.5% of additives, wherein the additives comprise a modified waterproof material and a thickening agent. Mass ratio of the modified waterproof material to the thickening agent is 0.63:1. The modified waterproof material is one or a mixture of cellulose ether, an air entraining agent or a water repellent. The thickening agent is mortar thickening powder. The product has durability, good water-repellent performance, strong adhesion stress and low shrinkage, is convenient for construction, has stable quality, and has good ageing resistance and waterproofness. Test results of the product accord with the national standard of ''pre-mixed mortar'' GB/T25181-2010.

Description

Be dry mixed waterproof mortar and preparation technology thereof
Technical field
The present invention relates to building mortar, espespecially one is dry mixed waterproof mortar.
Background technology
Being dry mixed waterproof mortar is build and apply material very widely in fitting-out work field, refer to that the aggregate (as quartz sand) of drying screening process, inorganic coagulation material (as cement) and additive (as polymkeric substance) etc. carry out a kind of particulate state or the powdery of physical mixed by a certain percentage, building site is transported to form packed or in bulk, add water the material that can directly use after mixing and stirring, and has thin layer and play the effects such as bonding, liner, protection, waterproof and decoration.The material cost of existing dry-mixed mortar is high, and building energy conservation is poor, construction workability is poor, cohesive force is low, impermeability is poor, for wall coating and ground, underground project waterproof layer, the coat of plaster hollowing easily caused, ftracture, come off and the problem such as seepage, so be just difficult to ensure to construction quality, needing in blending process with adding admixture simultaneously, being therefore difficult to the quality ensureing product.
Summary of the invention
For solving the problem, the invention provides that a kind of waterproof impervious characteristic is good, weather resistance and cohesive force is strong, shrinking percentage is low, and just simple with construction, steady quality, what have good ageing-resistant and water resistance is dry mixed waterproof mortar.For achieving the above object, the technical solution used in the present invention is
One is dry mixed waterproof mortar, it is characterized in that, comprises the component of following mass percent:
Wherein, described admixture comprises modified water-proofing material and viscosifying agent, and the mass ratio of modified water-proofing material and viscosifying agent is 0.63:1;
Described modified water-proofing material is one or more mixtures of ether of cellulose, air entrapment agent or hydrophober, and described viscosifying agent is mortar densification powder.
As the preferred scheme of one, described in be dry mixed the component that waterproof mortar comprises following mass percent:
As the preferred scheme of one, described in be dry mixed the component that waterproof mortar comprises following mass percent:
As the preferred scheme of one, described in be dry mixed the component that waterproof mortar comprises following mass percent:
As the preferred scheme of one, described cement is P.O42.5 cement.
Beneficial effect of the present invention is, raw material of the present invention have employed limestone deposit, and adopt waste resource flyash, effectively reduce the cost being dry mixed waterproof mortar, the waterproof impervious characteristic of product is good, cohesive force is strong, shrinking percentage is low, and be provided with admixture, do not need to add again in construction process, construction simple and fast, steady quality, have good weather resistance, ageing-resistant and water-proof function, its test-results all meets the requirement of national standard " premixing mortar " GB/T25181-2010.
Embodiment
Below by specific embodiment, the invention will be further described.
Wherein in admixture, the quality of modified water-proofing material and viscosifying agent is 5 ㎏ and 8 ㎏, and modified water-proofing material adopts the mixture of ether of cellulose, air entrapment agent and hydrophober, and described viscosifying agent adopts mortar densification powder, and cement adopts P.O42.5 cement.
Embodiment one
Adopt the component of following quality, what be fully mixed and made into grade M10 is dry mixed waterproof mortar:
Embodiment two
Adopt the component of following quality, what be fully mixed and made into grade M15 is dry mixed waterproof mortar:
Embodiment three
Adopt the component of following quality, what be fully mixed and made into grade M20 is dry mixed waterproof mortar:
Three kinds of different gradess that above-mentioned each mass component is made be dry mixed waterproof mortar, carry out test of products according to the national standard of " premixing mortar " GB/T25181-2010, draw test-results as shown in table 1.
Table 1:
Test-results of the present invention all meets the requirement of " premixing mortar " GB/T25181-2010, have employed limestone deposit, and adopt waste resource flyash, effectively reduce the cost being dry mixed waterproof mortar, the waterproof impervious characteristic of product is good, cohesive force is strong, shrinking percentage is low, and is provided with admixture, do not need to add again in construction process, construction simple and fast, steady quality, has good weather resistance, ageing-resistant and water-proof function.This product is applicable to the common waterproofing work of concrete casting building body and masonry structure surface, is applicable to the impervious waterproofing work such as building exterior wall face, interior decoration simultaneously.
Above embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that the common engineering technical personnel in this area make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determine.
