Abstract

The modifier for fine blast furnace powder is produced with anhydrous sodium sulfate 20-55 weight portions, industrial sodium carbonate 5-30 weight portions, calcium chloride 10-50 weight portions, sodium chloride 10-50 weight portions, aluminum sulfate 10-30 weight portions, fly ash 5-15 weight portions, and through crushing and mixing. Experiment shows that adding the modifier in 1 wt% into fine blast furnace powder can improve the activity of fine blast furnace powder effectively and raise its strength. The modifier may be also added into fine fly ash powder to reach similar effect, and the fine blast furnace powder and the fine fly ash powder are used in producing cement and concrete.

Description

A kind of granulating blast-furnace slag powder modifier
Technical field the invention belongs to graining blast-furnace cinder micro-powder additive technology field, relates to a kind of granulating blast-furnace slag powder modifier.
Background technology is present, the graining blast-furnace cinder micro-powder of production, and the ubiquity strength grade is than the low technical defective; use it for preparation cement or commerical ready-mixed concrete, can reduce production costs, still; the addition of graining blast-furnace cinder micro-powder is too high, will influence the quality of its product.
Summary of the invention the purpose of this invention is to provide a kind of granulating blast-furnace slag powder modifier, to solve technical problems such as prior art graining blast-furnace cinder micro-powder strength grade is lower, further improves the performance of graining blast-furnace cinder micro-powder.
Granulating blast-furnace slag powder modifier of the present invention is to be formed through pulverizing, mixed preparing by the following weight proportion raw material: 20～55 parts of anhydrous sodium sulphate; 5～30 parts of industrial sodium carbonates, 10～50 parts in calcium chloride, 10～50 parts in sodium-chlor; 10～30 parts in Tai-Ace S 150,5～15 parts in flyash.
Granulating blast-furnace slag powder modifier of the present invention; experimental results show that: in graining blast-furnace cinder micro-powder, add 1%; just can effectively improve the activity of graining blast-furnace cinder micro-powder; improve the strength grade of graining blast-furnace cinder micro-powder; the preparation process that also can be used for high fine powdered coal; improve the activity of flyash; also can be used for utilizing graining blast-furnace cinder micro-powder or high fine powdered coal to prepare the process of cement or commerical ready-mixed concrete; graining blast-furnace cinder micro-powder or the addition content of high fine powdered coal in cement or concrete be can increase substantially, cement or concrete manufacturing cost reduced.
Appended drawings is a process flow sheet of the present invention
Embodiment
Embodiment 1
Take by weighing raw material by following weight proportion:
20 parts of anhydrous sodium sulphate, 10 parts of industrial sodium carbonates, 10 parts in calcium chloride, 10 parts in sodium-chlor, 20 parts in Tai-Ace S 150,10 parts in flyash.
Preparation process such as accompanying drawing are dried sodium-chlor in advance again and to be pulverized, simultaneously with behind calcium chloride, the Tai-Ace S 150 separated pulverizing, again with anhydrous sodium sulphate, industrial sodium carbonate and flyash by the said ratio batching, stir through mixing then, packing gets final product.
Wherein pulverize after the sodium-chlor drying, require to adhere to moisture content less than 0.5%; Temperature requirement prevents high temperature dehydration less than 60 ℃ in the Tai-Ace S 150 crushing process; Calcium chloride, sodium-chlor and Tai-Ace S 150 require the fine particle diameter less than 1mm after crushed; Batching metering requires accurately, and mixed stirring requires environmental drying, stirs.
Embodiment 2
According to embodiment 1, get 45 parts of anhydrous sodium sulphate, 30 parts of industrial sodium carbonates, 5 parts in calcium chloride, 5 parts in sodium-chlor, 10 parts in Tai-Ace S 150,5 parts in flyash.

Claims (1)

1, a kind of granulating blast-furnace slag powder modifier is characterized in that being formed through pulverizing, mixed preparing by the following weight proportion raw material: 20～55 parts of anhydrous sodium sulphate, 5～30 parts of industrial sodium carbonates; 10～50 parts in calcium chloride; 10～50 parts in sodium-chlor, 10～30 parts in Tai-Ace S 150,5～15 parts in flyash.
