Description
Technical field
The present invention relates to building material field, a kind of high performance lightweight concrete is specifically related to, also relates to this light
The preparation method of matter high performance concrete.
Background technology
At present, known normal concrete is by cement, coarse aggregate, fine aggregate, water, additive and adds if necessary
Composite prepared by mineral admixture.Rubble, cobble of the coarse aggregate typically using particle diameter more than 5mm are used as coarse aggregate.With broken
, as coarse aggregate, sand as fine aggregate, 1m3 concrete weighs about 2400kg, therefore works deadweight is larger, causes ground for stone or cobble
Load increases, so that the expense of structure foundation treatment increases.
All it is that rubble appearance is irregular, gill shape is more so that produced with it as aggregate due to concrete with rubble and sand
The concrete for going out is each to dissimilarity, the service behaviour that the building that influence pours out builds.It is common mixed at the aspect of workability
Solidifying soil is also poor due to the pumping of the irregular low-slump concrete of aggregate appearance.
Basaltic Main Ingredients and Appearance is (also a small amount of silica, alundum (Al2O3), iron oxide, calcium oxide, magnesia
Potassium oxide, sodium oxide molybdena), wherein dioxide-containing silica at most, accounts for 45 to 50 or so percent.Black Warrior stone price is just
Preferably, distribution is wider than natural pumice, and southern area is also distributed.
The content of the invention
A kind of lightweight, high intensity, the good endurance provided it is an object of the invention to overcome disadvantages mentioned above, and can be with
Substantially isotropic high performance lightweight concrete is accomplished.
Another object of the present invention also resides in the preparation method for providing the high performance lightweight concrete.
A kind of high performance lightweight concrete of the invention, including following weight portion raw material：In terms of 1 part of cement, 0.6-0.9
Part lightweight fine aggregate, 0.9-1.25 parts of lightweight coarse aggregate, 0.25-0.55 parts of water.
A kind of above-mentioned high performance lightweight concrete, wherein：Additive can according to a conventional method be allocated into as needed.
A kind of above-mentioned high performance lightweight concrete, wherein：Lightweight fine aggregate is less than 4.75mm particle diameter hollow thin-wall balls.
A kind of above-mentioned high performance lightweight concrete, wherein：Lightweight coarse aggregate is more than 5mm particle diameter hollow thin-wall balls.
A kind of above-mentioned high performance lightweight concrete, wherein：Hollow thin-wall ball is Black Warrior stone hollow thin-wall ball.
A kind of above-mentioned high performance lightweight concrete, wherein：The preparation method of Black Warrior stone hollow thin-wall ball includes following step
Suddenly：
（1）Black Warrior stone raw material are ground into graininess；
（2）Black Warrior stone particle is sent to melting furnaces it is heated to 1450-1500 DEG C and is fused into liquid；
（3）Then the liquid shear outflow is pressed into hemisphere base into uniform segment mould；
（4）Two hemispheres base is connected into a complete hollow thin-wall ball at high temperature under high pressure.
A kind of preparation method of high performance lightweight concrete of the invention, above-mentioned component is uniformly mixed according to a ratio can.This
Invention compared with prior art, with obvious beneficial effect, as can be known from the above technical solutions：The present invention is hollow thin Black Warrior stone
Squash adds concrete as a kind of new aggregate, produces a kind of high performance lightweight concrete, and the concrete can be greatly
The deadweight of building member is reduced, reduces the load that ground is born.With this kind of lightweight, high intensity, good endurance concrete
The height of high-rise building can be so that further to be increased by comparison.The present invention is because the Black Warrior stone hollow thin-wall ball bone for using
Material appearance rule, so the concrete produced can substantially accomplish isotropism.Also it is excellent in terms of some of workability
The pumping of low-slump concrete can be improved the characteristics of general concrete, aggregate appearance rule and lightweight.It is of the invention
Concrete gravity is lighter, can improve the bearing capacity of component, and will not reduce concrete strength.And possess good durable
Property, concrete is respectively to the basic same sex.
