Abstract
The present invention relates to a kind of mineral admixture, belong to technical field of concrete additives.The technical problems to be solved by the invention are to provide a kind of early epistasis can more preferable mineral admixture.Mineral admixture of the present invention is made up of the component of following weight proportion：Flyash 25-45 parts, blast furnace slag 50-70 parts, 0.5-1.5 parts, sodium sulphate 1-3 parts, calcium oxide 1-3 parts of dihydroxy ethyl ethylenediamine.To use the industrial residues such as flyash and blast furnace slag be primary raw material to the present invention, not only by its twice laid, it is to avoid its environmental pollution, while the 15-25% of equivalent cement can be replaced, has saved cost.The early age strength of concrete that mineral admixture of the present invention is prepared is higher, improves the early epistasis energy of concrete.
Description
Technical field
The present invention relates to a kind of mineral admixture, belong to technical field of concrete additives.
Background technology
Concrete admixture is that, in order to improve concrete performance, using water wisely adjusts strength grade of concrete, in concrete mixing
When mix the natural or artificial powdered ore material that can improve concrete performance.Admixture can be divided into active admixture and nonactive
Admixture.Active mineral admixture is non-sclerous in itself or setting rate is very slow, but can be reacted with hydrated cementitious generation calcium oxide,
The nonactive mineral of such as hydrated product of the generation with gelling ability, such as flyash, ground granulated blast furnace slag, zeolite powder, silicon ash are blended
Material does not react with cement component substantially, such as lime stone, the material such as levigate quartz sand.
At present, although existing mineral admixture such as blast-furnace cinder, flyash, inclined kaolin, gangue etc. can improve coagulation
The endurance quality of soil, but early activity is low, it is difficult to meet the construction of the concrete prefabricated product required to early strength.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of early epistasis can more preferable mineral admixture.
Mineral admixture of the present invention is made up of the component of following weight proportion：Flyash 25-45 parts, blast furnace slag 50-70 parts, two
AEEA 0.5-1.5 parts, sodium sulphate 1-3 parts, calcium oxide 1-3 parts.
Wherein, in order that the early epistasis of mineral admixture can more preferably, above-mentioned mineral admixture is preferably by the component of following weight proportion
Composition：Flyash 30-40 parts, blast furnace slag 55-65 parts, 0.8-1.2 parts of dihydroxy ethyl ethylenediamine, sodium sulphate 1.5-2.5 parts,
Calcium oxide 1.5-2.5 parts.
Further, above-mentioned mineral admixture is most preferably made up of the component of following weight proportion：35 parts of flyash, blast furnace slag
60 parts, 1 part of dihydroxy ethyl ethylenediamine, 2 parts of sodium sulphate, 2 parts of calcium oxide.
To use the industrial residues such as flyash and blast furnace slag be primary raw material to the present invention, not only by its twice laid, it is to avoid its environment
Pollution, while the 15-25% of equivalent cement can be replaced, has saved cost.The concrete that mineral admixture of the present invention is prepared is in early days
Intensity is higher, improves the early epistasis energy of concrete.
Specific embodiment
Mineral admixture of the present invention is made up of the component of following weight proportion：Flyash 25-45 parts, blast furnace slag 50-70 parts, two
AEEA 0.5-1.5 parts, sodium sulphate 1-3 parts, calcium oxide 1-3 parts.
Wherein, in order that the early epistasis of mineral admixture can more preferably, above-mentioned mineral admixture is preferably by the component of following weight proportion
Composition：Flyash 30-40 parts, blast furnace slag 55-65 parts, 0.8-1.2 parts of dihydroxy ethyl ethylenediamine, sodium sulphate 1.5-2.5 parts,
Calcium oxide 1.5-2.5 parts.
Further, above-mentioned mineral admixture is most preferably made up of the component of following weight proportion：35 parts of flyash, blast furnace slag
60 parts, 1 part of dihydroxy ethyl ethylenediamine, 2 parts of sodium sulphate, 2 parts of calcium oxide.
Specific embodiment of the invention is further described with reference to embodiment, does not therefore limit the present invention to institute
Among the scope of embodiments stated.
The preparation of the mineral admixture of the present invention of embodiment 1
Flyash 250kg, blast furnace slag 705kg, dihydroxy ethyl ethylenediamine 5kg, sodium sulphate 10kg, calcium oxide 30kg are taken, is mixed
It is even, obtain final product mineral admixture.
The preparation of the mineral admixture of the present invention of embodiment 2
Flyash 440kg, blast furnace slag 505kg, dihydroxy ethyl ethylenediamine 15kg, sodium sulphate 30kg, calcium oxide 10kg are taken, is mixed
It is even, obtain final product mineral admixture.
The preparation of the mineral admixture of the present invention of embodiment 3
Flyash 350kg, blast furnace slag 600kg, dihydroxy ethyl ethylenediamine 10kg, sodium sulphate 20kg, calcium oxide 20kg are taken, is mixed
It is even, obtain final product mineral admixture.
The mineral admixture prepared using embodiment of the present invention 1-3, is used in addition concrete, replaces the 15-25% of equivalent cement,
Contrasted using the concrete without mineral admixture of the present invention simultaneously, the compression strength of its 3d and 28d is determined respectively, tied
Fruit is as shown in table 1.Using P.052.5, water reducer is polycarboxylate water-reducer (PCA) to wherein cement, cobble-stone diameter 5-20mm,
River sand modulus of fineness is 2.8.
