Description
Technical field
The present invention relates to a kind of light high strength concrete materials and preparation method thereof, belong to building material technical field.
Background technology
Light high strength concrete (HSLC) has the spies such as light-weight, intensity is high, density is low, elasticity modulus is low, durability is good
Point, good heat preservation, insulative properties, the U.S. in 1913 are first light high strength concrete with the klining haydites of book structure that circles round
Development lay a good foundation, fast development has been obtained in countries in the world since the sixties in last century, particularly in the U.S., north
Europe, Japan and other countries are widely used in skyscraper, super-high building structure, Longspan Bridge and urban interchange and ocean
In engineering.
It starts to walk relatively late, to be mainly subject to aggregate self-strength for the research and development of light high strength concrete in China
Limitation, the intensity of concrete hardly result in raising, and are typically to reach raising concrete strength by increasing the dosage of cement
Purpose, but since increasing for cement consumption can cause mixed lightweight aggregate to float, segregation phenomenon occurs, so as to cause mixed
The intensity for coagulating soil declines, and elasticity modulus and stress distribution are uneven, seriously constrain being widely applied for light high strength concrete
And application.
Meanwhile China has carried out numerous studies in terms of the large-scale application of light high strength concrete.Such as：Patent of invention Shen
Please " light high strength concrete and its preparation method "（CN102659363 A）Increased by the compound use of exciting agent and tackifier
The dosage of low-density cementitious material, promote slurry sticks poly- property, on the basis of hardened paste mechanical property is ensured, reaches significantly
Degree reduces hardened paste unit weight purpose；Patent of invention " a kind of High-strength lightweight concrete "（ZL201310702446.4）In swelling
Under the action of soil, by the activation of calcium carbonate and zinc sulfate, not only resistance to compression, tensile resistance are strong for gained concrete, but also quality
It is relatively light；Application for a patent for invention " a kind of light high strength concrete and preparation method thereof "（CN104803645 A）Using molecular sieve and
Air entraining agent collective effect introduces a large amount of micro- stomatas little to intensity effect in concrete, further reduces high-strength light coagulation
The unit weight of soil promotes the application range of light high strength concrete.
Although more than technology prepares the lightweight concrete material of advantages of higher compressive strength to a certain extent, for being mixed
The raw material entered are more demanding, and industrial processes are complex, and the apparent density for the concrete material prepared cannot obtain
It effectively reduces, there are certain feasibility problems during practice of construction.
Oil-well cement is used in oil gas field well cementation field as a kind of high-strength cement, reaches after shaping in the short period
Comparable intensity, with good stability after hardening, impervious, corrosion stability.The high intensity of oil-well cement, corrosion stability etc. is excellent
It is benign to be used in light high strength concrete that the compression strength of concrete will to be effectively improved, at the same ensure light high strength concrete compared with
Low-density, this is for the comprehensive performance important in inhibiting of raising light high strength concrete.
The content of the invention
It is an object of the invention to provide a kind of light high strength concrete material, the strength grades of the light high strength concrete
For LC50~LC60, apparent density is controlled in 1500~1650kg/m3, there are the spies such as good antidetonation shock attenuation, durable, light-weight
Point, and nontoxic, beneficial to environmental protection, the defects of overcoming the prior art and deficiency.
Another object of the present invention also resides in the preparation method for providing above-mentioned light high strength concrete material, and this method combines
Current light high strength concrete technology and oil gas field well cementation field advanced material, not only substantially increase existing high-strength light coagulation
Compression strength, the corrosion resistance of soil, while ensure that the good durability of light high strength concrete, while this method production cycle
Short, raw material valency is low to be easy to get, and application easy to promote large-scale has a vast market prospect.
