Abstract
The invention discloses an emulsified asphalt modified cement base composite material, which is mainly prepared from the following components in parts by weight: 5 parts of water, 10 parts of cement, 20 to 30 parts of natural river sand, 0.8 to 2 parts of emulsified asphalt, 0.1 to 0.3 part of initiator, 7 wt% of carboxymethyl cellulose, and 1 wt% of calcium chloride. The composite material has the following advantages: (1) the permeability resistant property is obviously enhanced; (2) the corrosion resistant performance is effectively enhanced, the brittleness is prominently reduced, and the deformability is improved; (3) the carbonization resistant performance is good, and at the same time, low temperature anti-cracking property and durability of asphalt mixture are both improved.
Description
Technical field
The present invention relates to field of compound material, particularly relate to a kind of modified cement-based composite of emulsified asphalt.
Background technology
Two or more chemical property or the mutually different material of tissue, the material being combined into the level of microcosmic or macroscopic view, all can become composite, this is of common occurrence in our engineering construction and daily life, as mixed the mud wall of straw, cement concrete, ceramic metal, rubber tyre etc., the existing history for a long time of polymer application in cement mortar and cement concrete, but it is not promoted so far, most important reason is owing to polymer is expensive, and the outstanding advantages of this polymer of emulsified asphalt is low price, the polymer modified cement based composite material using emulsified asphalt preparation economic has important development prospect, therefore, how to study a kind of low cost and the good cement-base composite material of combination property has become to be presently required and solves the technical problem that.
Summary of the invention
It is an object of the invention to the problem above overcoming prior art to exist, for realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of modified cement-based composite of emulsified asphalt, is mainly made up of the component of following mass fraction: 5 parts of water, cement 10 parts, natural river sand 20～30 parts, emulsified asphalt 0.8～2 parts, initiator are 0.1～0.3 part.
Further, emulsifier content is water 5% in described emulsified asphalt.
Further, described natural river sand mean diameter is 40～60 mesh.
Further, one or more in potassium peroxydisulfate initiator, sodium peroxydisulfate initiator, ammonium persulfate initiator or azodiisobutyronitrile initiator of described initiator.
Further, described composite contains the carboxymethyl cellulose of 7%wt, the calcium chloride of 1%.
The medicine have the advantages that 1, permeability resistance has clear improvement；2, being effectively improved corrosion resistance and fragility is significantly reduced, deformability increases；3, anti-carbonation properties is preferable, improves low-temperature cracking-resistance and the durability of asphalt simultaneously.
Detailed description of the invention
Below in conjunction with embodiment, describe the present invention in detail.
A kind of modified cement-based composite of emulsified asphalt, is mainly made up of the component of following mass fraction: 5 parts of water, cement 10 parts, natural river sand 30 parts, emulsified asphalt 2 parts, initiator are 0.3 part.
Wherein, the emulsifier content in emulsified asphalt is the 5% of water.
Wherein, natural river sand mean diameter is 40～60 mesh.
Wherein, one or more in potassium peroxydisulfate initiator, sodium peroxydisulfate initiator, ammonium persulfate initiator or azodiisobutyronitrile initiator of initiator.
Wherein, composite contains the carboxymethyl cellulose of 7%wt, the calcium chloride of 1%.
Embodiment 1: a kind of its preparation technology following steps of the modified cement-based composite of emulsified asphalt: stop after adding water and other auxiliary agent continuation stirring 5min after in proportion cement, fluvial sand being put into blender stirring 1min, the whole glue sand being stirred are uniformly charged in die trial at twice, stop after the dynamic 2min of resonance, after curing molding, complete goods.
The foregoing describe the citing of the present invention, illustrate principal character and advantages of the present invention.It should be appreciated that the present invention is not restricted to the described embodiments, the present invention also has various changes and modifications, and these changes and improvements both fall within scope of the claimed invention.
