[0027] The present invention also provides a concrete preparation method, which comprises mixing the above concrete composition with water.

[0028] According to the present invention, the amount of water used is particularly limited, and the conventional amount in the field can be used. Preferably, based on 100 parts by weight of the stone, the amount of water used is 23-29 parts by weight; more preferably 25-27 parts by weight.

[0029] The present invention also provides a concrete prepared by the above method.

[0030] The concrete according to the invention has sufficient strength, good compression resistance and heat and abrasion resistance.

[0040]After proportioning the components in Table 2, they were mixed with water to prepare concrete; wherein, relative to 100 parts by weight of high-titanium heavy slag, the amount of water was 25 parts by weight. The average particle size and component content of high-titanium heavy slag are shown in Table 1, and the compressive strength, heat resistance, wear resistance and slump of the obtained concrete are shown in Table 3.

Abstract

The present invention discloses a concrete composition, and concrete and a preparation method thereof, wherein the concrete composition contains cement, sand, stone, fly ash and scrap iron, and the stone contains high titanium heavy slag. According to the present invention, the concrete composition has advantages of low cost and environmental protection, and the obtained concrete has characteristics of sufficient strength, good compression resistance, good heat resistance, and good wear resistance.

Description

technical field [0001] The invention relates to a concrete composition and concrete and a preparation method thereof. Background technique [0002] The aggregate of heat-resistant and wear-resistant concrete is one of the important factors to ensure that the concrete meets the technical requirements in a high-temperature environment, and it is also a key factor to save costs and facilitate construction. [0003] At present, granite crushed stone and andesite are generally used in China to prepare heat-resistant and wear-resistant concrete at 300°C to 600°C, but the cost of using granite crushed stone or andesite is relatively high. Moreover, over-exploitation of gravel destroys natural vegetation and causes soil erosion. [0004] Therefore, there is an urgent need for a low-cost, environmentally friendly concrete material with sufficient strength, good compression resistance, and good heat and wear resistance. Contents of the invention [0005] The purpose of the present...
