Abstract
The invention discloses anti-discharge high-strength concrete which is prepared from the following raw materials in parts by weight: 100 parts of cement, 70 parts of water, 30-35 parts of ganister sand, 20-25 parts of sodium silicate, 15-18 parts of calcium carbonate, 11-15 parts of gypsum powder, 5-8 parts of sodium sulphide, and 2-6 parts of nickel oxide. The anti-discharge high-strength concrete adopts the ganister sand to replace a part of cement, so that the strength of the concrete can be effectively improved by adding sodium silicate, the discharge reaction is prevented under the action of sodium sulphide and nickel oxide and the operation condition of high strength of high external friction and the like, and an accident caused by discharge reaction formed by a high-strength operation for a long period of time is reduced.
Description
Technical field
The present invention relates to a kind of concrete.
Background technology
Concrete, referred to as " concrete (t ó ng) ": refer to the general designation that is cemented to overall engineered composite material by gelling material by gathering materials.Conventionally concrete one word of saying refers to cement makes gelling material, and sand, masonry gather materials; Coordinate by a certain percentage with water (adding or do not add admixture and adulterant), through stirring, moulding, maintenance and cement concrete, also claim normal concrete, it is widely used in civil engineering work.
When cement is applied as some high-strength materials, such as expressway, railroad sleeper etc., under the effects such as extraneous high strength friction, its surperficial atom can form free state, and provide electron production exoelectrical reaction, affect the normal operation of train, automobile etc. or easily cause the accident.
Summary of the invention
The technical problem to be solved in the present invention is to overcome existing defect, and a kind of anti-discharge high-strength concrete being suitable under high-strength working is provided.
Object of the present invention is carried out specific implementation by the following technical programs:
A kind of anti-discharge high-strength concrete, the each component of its raw material by weight, 100 parts of cement, 70 parts, water, silica flour 30-35 part, water glass 20-25 part, calcium carbonate 15-18 part, terra alba 11-15 part, sodium sulphite 5-8 part, nickel oxide 2-6 part.
As preferred version, above-mentioned anti-discharge high-strength concrete, the each component of its raw material by weight, 100 parts of cement, 70 parts, water, 33 parts of silica flours, 21 parts of water glass, 16 parts, calcium carbonate, 14 parts of terra albas, 7.5 parts, sodium sulphite, 3 parts of nickel oxide.
Beneficial effect of the present invention:
The anti-discharge high-strength concrete of the present invention, adopt silica flour to replace part of cement, the interpolation of water glass can effectively improve concrete intensity, and under the effect of sodium sulphite and nickel oxide, make it under large operating condition such as the intensity of extraneous high friction etc., stop exoelectrical reaction, reduce the generation of the accident causing because of long-time high-intensity operation formation exoelectrical reaction.
