Abstract
The invention discloses anti-knock high-toughness concrete, and relates to a cement based composite material in the field of construction material, in particular to concrete with high strength and good toughness. The anti-knock high-toughness concrete is prepared from the following components in parts by weight: 20%-25% of cement, 15%-40% of fine aggregate, 25%-30% of coarse aggregate, 1%-10% of polystyrene foam particles, 1%-10% of admixture and 3%-20% of steel fibers or carbon fibers. Compared with the prior art, the concrete has the advantages that by addition of new components, the prepared concrete product has stronger toughness, cracks on walls are reduced, the service life is increased, and simultaneously the tensile strength, folding strength, shock resistance and fireproofing antiknock property of the concrete are improved.
Description
Technical field
The present invention relates to the cement-base composite material of a kind of building material field, particularly relate to a kind of strength high toughness good
Concrete.
Background technology
The material used between floors is referred to as construction material, is the material used in civil engineering and architectural engineering
It is referred to as.Construction material can be divided into structural material, ornament materials and some proprietary material, and structural material includes timber, bamboo wood, stone
Material, cement, concrete, metal, brick and tile, pottery, glass, engineering plastics, composite etc.；Ornament materials include various coating,
Paint, coating, veneer, assorted ceramic tile, there is the glass etc. of special-effect；Proprietary material refers to for waterproof, moistureproof, anticorrosion, prevents
Fiery, fire-retardant, sound insulation, heat insulation, be incubated, sealing etc..
Wherein the concrete in structural material is most commonly used in being current construction material.Concrete refers to by being gelled
Material is cemented to the general designation of the engineered composite material of entirety by gathering materials.Concrete one word generally said refers to make gelling material with cement
Material, sand, masonry gather materials, and coordinate by a certain percentage with water (can contain additive and admixture), agitated obtained by cement concrete,
Also referred to as normal concrete, it is widely used in civil engineering.Concrete material is a kind of durable material, but is substantially one
Plant porous material heterogeneous, under the corrosion function of the medium of carbon dioxide, water, chlorion, sulfate etc., be unavoidably subject to
Corroding to the impact of foeign element, concrete can accelerate the failure, and service life is greatly shortened.
The inorganic coagulation materials such as cement, lime, gypsum and water are mixed and concrete mix can be made to have plasticity；And then pass through
Chemically and physically chemistry is made the condensation hardening of various concrete and is produced intensity.It is, in general, that drinking water all can meet
The requirement of concrete mixing water.In water, acid, alkali, salt and the organic matter of excess all can produce injurious effects to concrete.Collection
Material does not only has filling effect, and has a major impact the character such as unit weight, intensity and the deformation of concrete.
Owing in concrete, uneven distribution, dissimilar and number is both contained in cement mortar body and interfacial transition zone
Solid phase, hole and the microcrack of amount, so that concrete is easily affected by external environment and causes concrete microcrack to extend,
Harmful substance invades and causes concrete deterioration, reduces concrete durability, affects the service life of concrete structures.Simultaneously existing
Some concrete material tensile strength is low, and the low shock resistance of rupture strength is poor, and fire-and explosion-proof Performance comparision is weak, concrete tough
Property is poor.
Summary of the invention
It is an object of the invention to provide a kind of antiknock high tenacity concrete, by adding new composition so that make
Concrete product has stronger toughness, reduces the crackle on wall, increases the service life, and can improve the anti-of concrete simultaneously
Tensile strength, rupture strength, shock resistance and fire-and explosion-proof performance.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: provide a kind of antiknock high
Toughness concrete, described antiknock high tenacity concrete component and weight portion are as follows: cement: 20%-25%；Fine aggregate: 15%-40%；
Coarse aggregate: 25%-30%；Polystyrene foam particles: 1%-10%；Additive 1%-10%；Steel fibre or carbon fiber: 3%-20%；Institute
The polystyrene foam particles stated, particle diameter 1-3mm；32.5 grades or 42.5 grades portland cements of described cement selection or common
Portland cement；Described coarse aggregate includes rubble, and particle diameter is 5-25mm；The powder containing quantity of described rubble is 5.2%, rubble
Counting mould degree accurately is 1.5；Described fine aggregate includes river sand and mica powder, Sha Wei II district, river medium sand, and clay content is less than 3%；Described
Additive is by more than one mixing in water reducer, phenol, polyvinyl alcohol, acetate, glycerine and polyacrylate material
Become；Described water reducer is with the wood calcium ordinary water-reducing agent as representative；Described steel fibre length and carbon fiber length are all 1-45
Millimeter.
Present invention advantage the most relatively is: by adding new composition so that the concrete system made
Product have stronger toughness, reduce the crackle on wall, increase the service life, can improve simultaneously concrete tensile strength,
Rupture strength, shock resistance and fire-and explosion-proof performance.
