Problems solved by technology

Granulated blast furnace titanium slag is an inactive material, and its dosage in cement is less than 10%. The amount of finely ground high-titanium slag used in concrete and mortar is also smaller, which lacks economy, so granulation Blast furnace titanium slag has been underutilized in the construction industry as admixture or admixture

Embodiment approach

[0009] 1. The proportion of blast furnace titanium slag composite fine powder is 40%-100%, and the proportion of fly ash is 0-60%.

[0010] 2. The proportion of blast furnace titanium slag composite fine powder is 40%-90%, the proportion of fly ash is 5%-60%, and the proportion of steel slag is 5%-60%.

[0011] The main physical and chemical indicators of the above-mentioned blast furnace titanium slag composite micropowder are: TiO 2 5%-23%, specific surface area ≥ 400m 2 / kg, 28d compressive strength ratio ≥ 75%. After the above-mentioned blast furnace titanium slag composite micropowder is prepared, an additive that accounts for no more than 5% of the weight of the blast furnace titanium slag composite micropowder is added. Additives are natural gypsum, calcined gypsum, Yuanming powder, calcium sulfoaluminate and water reducing agent alone or in combination.

[0012] The specific surface area of ​​the fine-grained blast furnace titanium slag and steel slag is ≥400m 2 / k...

Embodiment 1

[0017] The blast furnace titanium slag composite micropowder is produced by adding 5% by weight of the above-mentioned additives according to 100% of the blast furnace titanium slag.

Embodiment 2

[0019] Prepared according to 40% of blast furnace titanium slag and 60% of fly ash fine powder. First, the mixed raw materials are dried and ground separately, and then the ingredients are mixed evenly, and the finished product is packaged.

Abstract

The present invention is one kind of composite micro powder of blast furnace titanium slag, which is used as non-active material added into cement, concrete and mortar. The composite micro powder contains blast furnace titanium slag, flyash and steel slag, and is added into cement, concrete and mortar with the amount being more than 10 % of cement. Using the blast furnace titanium slag in large scale can lower the production cost and improve the performance of cement, concrete and mortar.

Description

technical field [0001] The invention relates to a composite micropowder containing blast furnace titanium slag, particularly a composite micropowder which is mixed into cement, concrete and mortar as an inactive material. Background technique [0002] Ordinary blast furnace slag powder is an active mixed material. It only needs to be ground separately or mixed with a small amount of gypsum to be ground. It has been widely used in cement, concrete and mortar as a mixture or admixture. Granulated blast furnace titanium slag is an inactive material, and its content in cement is less than 10%. The amount of finely ground granulated high titanium slag used in concrete and mortar is also smaller, and it lacks economy. Therefore, granulation Blast furnace titanium slag has not been utilized as a mixture or admixture in the construction industry. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a composite micropowder containing blast furnace t...
