Abstract
The invention discloses high steel fiber concrete, which is prepared from the following components in parts by weight: 150 to 200 parts of cement, 120 to 160 parts of steel fiber, 80 to 120 parts of quartzite, 60 to 80 parts of silicon dioxide, 40 to 50 parts of polyacrylate, 30 to 60 parts of synergist, 20 to 40 parts of sodium sulfide and 120 to 180 parts of water. By using the high steel fiber concrete, in comparison with a conventional technique, the bending strength and the toughness of concrete, a limited crack width and the capacity of resisting cracks in surfaces of the concrete as well as antidetonation and fireproofing are improved; raw materials are low in cost; the high steel fiber concrete is applicable to a high-toughness construction requirement, meanwhile, has no pollution, and is harmless to an ambient environment.
Description
Technical field
The invention belongs to field of constructional engineering material, be specifically related to a kind of high steel fiber reinforced concrete.
Background technology
Concrete is as existing more than the 100 year history of construction material, and the advantage of concrete is, comprcssive strength is high, draws materials easily, and easy-formation is cheap, can be combined with other materials and make various heavy firmware, but concrete deadly defect is that tension is strong
Spend low, easy to crack, thus reduce the bearing capacity reduction of service life of xoncrete structure, become the hidden danger of various disaster accident.
Concrete is with concrete as matrix, the general name of cement based made by other fibrous materials mixing material, carries out and can improve the multiple performance of concrete, so fiber concrete is to change due to what fiber concrete can well inhibit crack
The effective ways of kind concrete stress performance.But the concern that people are more for a long time, the reinforced effects of single concrete, the most different types of fibrous material is different to the reinforced effects of concrete.Some can improve the preliminary examination cracking degree of concrete
Preventing concrete cracking, after some can improve concrete cracking, degree of participation limits fracture width development, and some has antiknock fire resistance property etc., can be complementary thus generation is just mixing effect between them by different fibrous materials according to fibrous material theory
Should, 1 effect adding 1 more than two can be reached, thus produce dependable performance and there is the novel height of preferable economic and social benefits
Performance fibers material.
Existing fiber concrete Tensile strength is low, and the low shock resistance of rupture strength is poor, and fire-and explosion-proof Performance comparision is weak, and therefore we need to provide a kind of tencel concrete material, thus promote the toughness of concrete.
Summary of the invention
Goal of the invention: present invention aims to the deficiencies in the prior art, it is provided that a kind of high steel fiber reinforced concrete, improves concrete flexural strength and toughness, the fracture width of restriction, opposing concrete surface be full of cracks and antiknock fire resistance property.
Technical scheme: in order to reach foregoing invention purpose, the present invention is specifically achieved like this: a kind of high steel fiber reinforced concrete, component including following parts by weight: cement 150 ~ 200 parts, steel fibre 120 ~ 160 parts, quartz 80 ~ 120 parts, silicon dioxide 60 ~ 80 parts, polyacrylate 40 ~ 50 parts, synergist 30 ~ 60 parts, 20 ~ 40 parts of sodium sulfide, 120 ~ 180 parts of water.
Wherein, described cement is alkaline cement.
Wherein, described synergist is CTF Concrete synergist.
Wherein, described sodium sulfide is anhydrous sodium sulfide.
Beneficial effect: the present invention is compared with conventional art, and scientific formulation, cost of material is low, it is adaptable to high tenacity building requirements, meanwhile, pollution-free, harmless to surrounding.The fiber concrete of the present invention is possible to prevent concrete cracking, improve concrete flexural strength and toughness, the fracture width limited, opposing concrete surface be full of cracks and antiknock fire resistance property, material of the present invention is beneficial to high-volume construction, can be widely applied to the xoncrete structure in the fields such as building, water conservancy, municipal traffic, ocean military project.
