Description
Technical field
It the present invention relates to the use of negative poisson's ratio foamed material and design a kind of New Style Concrete Materials for being not easy to crack and flake off
Method, belong to new material and new construction field.
Background technique
Reinforced concrete structure is a kind of structure type very widely used in building structure, is had cheap and steady
Qualitative good feature, will long-term existence in the infrastructure construction in China.But concrete due to material, match ratio with
And crack and flake off phenomenon caused by the problems in work progress and can be found everywhere, it greatly affected concrete material in building work
Application in journey.
1987, conventional polyurethanes foam was put into aluminium-making mould by American scholar Lakes, right again after the three-dimensional compression of progress
It is heated, is cooled down and relaxation processes, the auxetic polyurethane foam that Poisson's ratio is -0.7 has been made, this is first in the world
Made auxetic foamed plastics.Since then, the research of auxetic foam starts active.Currently, negative poisson's ratio foamed material
Type is increasingly various, preparation process is also greatly improved, and has the characteristics that preparation is convenient and low in cost.With conventional solid material
Material is compared, and foamed material has excellent specific strength, specific stiffness, good buffering energy-absorbing, rich and changeful size and inside
The advantages that micro-structure, is provided simultaneously with the functions such as filtration of sound, sound insulation, heat-insulated, humidity, can meet more under some extreme service environments
Functional requirement.The new material kind that negative poisson's ratio foamed material has a high potential as one, be expected to be applied to textile, industry,
Space flight, protection, biomedicine, sensor and other fields.
The introducing of negative poisson's ratio material can be effectively improved the stress distribution and cracking phenomena of concrete surface in concrete.
There is both sides advantage in the negative poisson's ratio foamed material that is wrapped laterally of the concrete material of axial compression: on the one hand, coagulation
When being pressurized lateral expansion can occur for soil material, can generate pressure to the negative poisson's ratio foamed material for being wrapped in external, make negative pool
Pine assembles than material to compressive region, can play effect of contraction to the cracking of concrete；On the other hand, it can reduce since concrete is opened
Split the pollution of the dust and particulate matter that peel off and generate to environment.Negative poisson's ratio material is widely used to various industries and takes at present
Preferable effect is obtained, while various New Style Concrete Materials and concrete composite material emerge one after another.The present invention is by negative pool
Pine is effectively combined than foamed material and concrete material, the advantage of two kinds of materials is utmostly played, so that development of new is embedding
Close the concrete material of negative poisson's ratio foam.
Summary of the invention
The purpose of the present invention is in view of the defects existing in the prior art, by negative poisson's ratio foamed material and the organic knot of concrete
It closes, has designed and prepared a kind of chimeric negative poisson's ratio foam volume New Style Concrete Materials, and propose specific implementation method, compared with
