Embodiment 1

[0027] Mix cement, high-titanium blast furnace slag, and high-titanium blast furnace slag sand with different particle sizes according to the ratio in Table 1, and then add water to mix to form concrete slurry, and then use a mold to cast a cuboid shape. The size length×width×height is 390mm×190mm×190mm; one of the cuboid-shaped surfaces with length×width 390mm×190mm and the opposite surface are provided with two through holes 1 through hollow bricks, and the diameter of the through holes 1 140mm; the distance between the axes of the two through holes 1 is 190mm, and the two through holes 1 are located in the middle of the cuboid shape; after pouring, the hollow brick with excellent thermal and mechanical properties can be obtained after conventional maintenance. The results are shown in Table 1.

Embodiment 2

[0032] The ratio of raw materials in embodiment two is carried out according to the ratio of the fifth group of experiments in embodiment one, and then cast into a cuboid shape with a mold. A surface of 390mm×190mm is provided with several through-holes 1 through the hollow brick between the opposite surface. The through-holes 1 are located in the middle of the rectangular parallelepiped, see Table 2.

Abstract

The invention discloses a high-titanium type blast furnace slag concrete hollow brick which gives consideration on both mechanical property and thermal performance, belonging to the field of concrete. The hollow brick is manufactured by casting concrete grout, and comprises the following raw material components according to the amount of the concrete grout of each cubic meter: 300-420kg of cement, 1,150-1,300kg of high-titanium type blast furnace slag sand with a particle size of 4.75-10mm, 680-800kg of high-titanium type blast furnace slag sand with a particle size of 0.16-4.75mm and 180-210kg of water. The high-titanium type blast furnace slag concrete hollow brick is produced by taking the high-titanium type blast furnace slag as a raw material, the production cost is saved, good economic benefits and social benefits are achieved, the requirements on compression resistance and shearing strength in the Brick Structure Design Specification GB50003-2001 are met, and the brick can be used as a wall material in construction engineering.

Description

technical field [0001] The invention belongs to the field of concrete, and in particular relates to a high-titanium blast furnace slag concrete hollow brick with both mechanical properties and thermal properties. Background technique [0002] High-titanium blast furnace slag is a kind of dense slag with a certain strength formed by the natural cooling or water cooling of the molten slag produced when Panzhihua Iron and Steel's ordinary blast furnace smelts vanadium-titanium magnetite. Compared with ordinary blast furnace slag, titanium dioxide (TiO 2 ) content is as high as 20% to 24%, and the calcium oxide content is low, that is, the slag produced by this raw material is an inactive material. Therefore, Panzhihua Iron and Steel has more than 55 million tons of high-titanium blast furnace slag that has not been used so far. It occupies an area of Thousands of mu, and the slag discharge volume is increasing by 3 million tons every year. Panzhihua Iron and Steel is already f...
