Description
Technical field
A kind of mortar and preparation method thereof belongs to mortar preparation technical field, relates generally to a kind of aerosil sand
Slurry and preparation method thereof.
Background technique
Mortar is a kind of Important building material in architectural engineering, is widely used in the masonry and plastering engineering of building.Mortar
It is many kinds of, performance constantly improves also with the development of modern architecture material, the tensile strength of common cement mortar,
Flexural strength and adhesion strength is high, poor toughness, easy to crack, with society development for cement and cement matrix intensity
It is required that it is higher and higher, increase calcium silicates etc. in cement kind, improve the intensity of cement mortar, while also bringing some new ask
Topic, for example, material brittleness problems, aquation heat problem, non-loaded deformation the problem of, in view of the above-mentioned problems, people start constantly
Research adds various substances in cement mortar kind, to enhance its toughness and caking property etc., although having done a variety of effort, cement mortar
Various aspects of performance still cannot reach engineering necessary requirement.
Aeroge is a kind of solid matter form, one of the solid of world's upper density very little.Density is 3 kilograms every cube
Rice.Because density is extremely low, at present most light aeroge only have 0.16 milligram it is per cubic centimeter, it is more slightly lower than atmospheric density, so
It is called " cigarette freezed " or " blue smoke ".Since the particle of the inside is very small (nanometer scale), so visible light dissipates when passing through it
Smaller (Rayleigh scattering) is penetrated, just as sunlight by air.Therefore, it, which is also looked at as sky, turns blue (if the inside does not have
Have the other things of doping), if seen against light somewhat rubescent.(sky is blue, and the sky of dusk is red).Due to
General 80% or more is air in aeroge, so there is extraordinary heat insulation, the aeroge of one-inch thickness it is suitable 20 to 30 pieces it is general
The heat insulating function of logical glass.Even if aeroge is placed between rose and flame, rose also can be at all lossless.As a kind of novel
Material has been applied to various field kinds, applies it in mortar, and the performance for improving cement mortar various aspects will become one
New direction.
Summary of the invention
To solve the above-mentioned problems, the invention discloses a kind of aerosil mortars and preparation method thereof, not only
The various aspects of performance of cement mortar is improved, and preparation process is simple, it is easy to accomplish.

The process kind of answering causes the influences such as the decline of its early strength, drying shrinkage increase, compression strength reduces, dispersed using the western clothes of water-reducing agent,
Mortar early strength can be improved in wetting action, while can also be improved the workability of mortar.
The fineness modulus range of the sand is between 2.2-2.6.
The fineness of the cement is 80 μm and tails over less than or equal to 2.5%.
Based on a kind of preparation method of aerosil mortar, include the next steps:
Step 1: determining cement-sand ratio, the dosage of every cube of mortar kind cement is determined according to cement-sand ratio；
Step 2: the system of stirring evenly after ethyl acrylate lotion, silica aerosil microballoon and polymer powder are mixed
At slurries A；
Step 3: cement, sand, mineral micro powder and water are mixed, and water-reducing agent is added, stirs evenly and mud B, mud is made
The consistency range of B is 68mm-73mm；
Step 4: slurries A is added in mud B, it is lasting to stir, and defoaming agent is added while agitating.
Compared with prior art, the present invention having the advantages that, polymer powder, silica airsetting in the present invention
Glue microballoon and the mixing of ethyl acrylate lotion, the mixed serum of formation are mixed with cement and sand, constitute a kind of net of elastic interpenetrating
Network structure, cement and sand are evenly distributed in the elastomeric network, improve the whole viscosity of cement mortar while also significantly
It improves its tensile strength, flexural strength, mortar bonding durability to improve, reduces its drying shrinkage, reduces cracking, while can be with
Increase frost resistance and anti-permeability performance.
