Embodiment 1

[0022] A concrete aggregate containing high titanium type blast furnace slag comprises the following components in parts by weight: 100 parts of high titanium type blast furnace slag aggregate, 50 parts of recycled concrete aggregate, 10 parts of modified straw fiber and 20 parts of seaweed fiber.

[0023] Among them, the high-titanium blast furnace slag aggregate is prepared by the following method: slowly cooling the high-titanium blast furnace slag, removing iron, crushing to less than 40mm, and then secondary crushing to less than 20mm, and then undergoing plasticity and sieving in turn to obtain Aggregate with a particle size of 5-15mm is the high-titanium blast furnace slag aggregate.

[0024] Concrete recycled aggregates are prepared by the following method: crush waste concrete, ball mill, screen out aggregates with a particle size of 5-15 mm, and then soak them in water and 10 wt% hydrochloric acid solution for 5 hours, take them out and wash them in medium Dry at 40°...

Abstract

The invention discloses a concrete aggregate containing high-titanium blast furnace slag and a preparation method thereof. The concrete aggregate containing high-titanium blast furnace slag comprises the following components in parts by weight: 100-500 parts of high-titanium blast furnace slag aggregate, 50-300 parts of concrete recycled aggregate, 10-15 parts of modified straw fibers and 20-30 parts of alginate fibers. The invention also discloses a preparation method of the concrete aggregate. According to the invention, recycling of high-titanium blast furnace slag and waste concrete is realized at the same time, the use requirements of thin concrete or dense reinforced concrete and the like can be met, and the problems of recycling of the high-titanium blast furnace slag and the waste concrete, poor performance of concrete aggregate and the like in the prior art are effectively solved.

Description

technical field [0001] The invention relates to the technical field of slag reuse, in particular to a concrete aggregate containing high titanium type blast furnace slag and a preparation method thereof. Background technique [0002] With the development of the economy, the current construction industry has achieved refined construction, and the requirements for concrete are becoming more and more stringent. Different parts and structures have different requirements for concrete, and the corresponding requirements for aggregate are also more detailed. Especially for pouring thinner concrete, and in structures with denser steel bars (especially multi-layer denser steel bar structures), there are special requirements for concrete aggregates. Due to the small amount of concrete used, it is generally not tested. Special research, its corresponding performance can not meet its use requirements. [0003] At the same time, mass production of concrete consumes a large amount of nat...
