Abstract
The invention discloses a using method for adopting calcium aluminum hydrotalcite as early a strength agent for cement concrete and belongs to the application technology field of hydrotalcite materials. The using steps are as follows: cement and freestones are mixed according to the ratio that the cement weight is 20 to 100 percent of the total weight of the cement and the freestone materials and the adding weight of the cement is recorded; the calcium aluminum hydrotalcite is added according to the ratio of 0.1 to 5 percent of the adding weight of the cement and the cement is stirred and mixed uniformly; water that accounts for 40 to 90 percent of the cement is added weight and uniform stirring and mixing is carried out again; finally, the well mixed concrete is added to a construction position. The using method has the advantages of improving the anti-fold capability and the compression resistant capability respectively to 60 to 70 percent and 70 to 80 percent and having easy operation.
Description
Technical field
The invention belongs to technical field of hydrotalcite material application, particularly a kind of with the using method of calcium aluminum hydrotalcite as cement concrete hardening accelerator.In the concrete operations calcium aluminum hydrotalcite is added in the concrete of forming with certain proportion by the 0.1%-5% with the cement quality ratio as new and effective cement concrete hardening accelerator.It is according to the difference of addition and the difference of cement concrete slurry, to the raising of early stage anti-folding of cement concrete material and compressive property respectively at 60%-70% and 70%-80%.
Background technology
Cement concrete is a major project material up to now.Its history is not long, and before about 160 years, because the appearance of portland (hydraulicity) cement, its importance is given prominence in construction work.It is still to belong to indispensable in 21 century, be difficult to displaced engineering materials.
Admixture is the 6th a kind of composition except that cement, water, sand, stone, mixing material (the levigate material of referring and synthesizing) in the cement concrete component, and it is a kind of chemical building material.Mix the later concrete performance of admixture and be greatly improved, mainly show concrete strength and weather resistance, purposes also greatly enlarges.Because parameter seldom, so cost does not increase.
Hardening accelerator is a kind of admixture of accelerate concrete early strength development.All need one long period because begin mix to setting and harden formation certain intensity from concrete.In order to quicken this process, quicken the turnover of template and pedestal, the curing time of the carrying of the stretch-draw of prestressed concrete or destress, concrete structures, shortening steam-curing concrete, the winter construction concrete reaches critical strength quickly, all wishes early strong.In a word, the demand to hardening accelerator is very huge.
The intercalation configuration material is a class new function material that develops rapidly in recent years.Its Modulatory character of constructing primitive and structure and variation for its development provides the broad space, can be used as catalytic material, separation and sorbing material, functional aid material, biological medicine material etc., are widely used in a plurality of fields of national economy.Since the nineties in 20th century, research institution and industrial community are to its pay attention to day by day both at home and abroad.Anionic intercalation configuration material is a class important branch of intercalation configuration material, and it is again based on hydrotalcite-based compound.Hydrotalcite-based compound comprises hydrotalcite (hydrotalcite) and houghite (hydrotalcite-like compound), its main body generally is made of the oxyhydroxide of two kinds of metals, therefore be called laminated dihydroxy composite metal hydroxide (layered double hydroxide is abbreviated as LDH) again.
Water insoluble and the organic solvent of calcium aluminum hydrotalcite, laminate structure is stable, and the hexagonal structure regularity of lamella is higher, can generate the particle of large-size.Containing a large amount of OH-in the calcium aluminum hydrotalcite structure, is a kind of solid alkali.Simultaneously because to bear the AFM of physical strength in its structure and pattern and the cement extremely similar, so think calcium aluminum hydrotalcite added in the cement concrete and can improve its early strength greatly.
Summary of the invention
The purpose of this invention is to provide a kind of with the using method of calcium aluminum hydrotalcite as new and effective cement concrete hardening accelerator.Solved the interpolation problem of calcium aluminum hydrotalcite when concrete construction.
Calcium aluminum hydrotalcite provided by the invention as the using method of high-efficiency cement concrete early strength agent is:
Cement, sandstone are accounted for the mixed of the 20%-100% of cement and sandstone material total mass by cement quality, and note the interpolation quality of cement; Press the 0.1%-5% interpolation calcium aluminum hydrotalcite that cement adds quality then, mix; Add the water of 40% to 90% quality that accounts for cement quality again, and mix once more; At last the concrete for preparing is made an addition to construction location.
Adopt day island proper Tianjin XRD-6000 type X-ray diffractometer that sample is carried out qualitative analysis.Curve is X-ray diffraction (XRD) spectrogram of the concrete powder that makes among the embodiment 1 among Fig. 1.
Adopt Japanese HITACHI S-4700N type scanning electronic microscope (SEM) to observe the pattern of moulding concrete powder.Fig. 2 is the SEM photograph of the concrete powder that makes among the embodiment 2.Calcium aluminum hydrotalcite is a hexagon in the sample, and particle size is about 2 μ m, with AFM in hydrated cementitious consistent appearance mutually.Fig. 3 is the SEM photograph of the concrete powder that makes among the embodiment 4.Calcium aluminum hydrotalcite is a hexagon in the sample, and particle size is about 1 μ m, with AFM in hydrated cementitious consistent appearance mutually.
What the present invention described is a kind of with the using method of calcium aluminum hydrotalcite as new and effective concrete additive, according to this addition means, according to the difference of addition and the difference of cement concrete slurry, to the raising of early stage anti-folding of cement concrete material and compressive property respectively at 60%-70% and 70%-80%.And easy handling.
