Beneficial effect of the present invention is: a kind of steel ring concrete of the present invention; Calculate by volume; It is by water: cement: sand: rubble: steel ring is 0.6～0.7: 1: 1: 1.6～2: 0.5～0.6 proportioning is processed, and wherein steel ring is the elongated rectangular shape block form.This steel ring concrete adopts steel ring to replace reinforcing bar; And steel ring is to produce the waste material that produces in the product process in many production; For example can produce a large amount of steel ring waste materials during punching press electronic transformer EI iron core, because steel ring is the waste material that continuous punching press produces, an iron core factory that has 10 left and right sides high velocity ram machines can produce about 100 tons of steel ring waste materials in every month; These steel ring waste materials are all sold salvage collection company as steel scrap with low price by factory; Be used for melting down steel-making, not only caused the waste of resource, and increased cost to manufacturer.If use these steel ring waste materials to produce a kind of steel ring concrete of the present invention, but then utilization of waste material turn waste into wealth, not only can economize on resources, reduce the cost of manufacturer, increase the income pattern, and this steel ring concrete cost is also lower.
Description of drawings:
Fig. 1 is the structural representation of steel ring according to the invention;
Fig. 2 is that the A of Fig. 1 is to synoptic diagram.
Embodiment:
Below in conjunction with accompanying drawing the present invention is further described: as depicted in figs. 1 and 2, a kind of steel ring concrete calculates by volume; It is by water: cement: sand: rubble: steel ring is 0.6～0.7: 1: 1: 1.6～2: 0.5～0.6 proportioning is processed; Said steel ring is the elongated rectangular shape block form, and the steel ring material is a siliconized plate, optional selecting to silicon steel or non orientating silicon steel; Certainly, said steel ring material also can be soft steel.As preferred embodiment, cement: sand: rubble: the volume ratio proportioning of steel ring is 0.7: 1: 1: 2: 0.6.Wherein, the length L of said steel ring is 28～41 millimeters, and width W is 6～8 millimeters, and thickness H is 0.2～0.5 millimeter, and rectangle hem width b is 0.8～1 millimeter.
Because steel ring is the waste material that continuous punching press produces, arranging does not have rule, is contained in to be loose condition (of surface) in the container, and stacking volume is bigger, and therefore, above-mentioned volume ratio proportioning can according to circumstances suitably be adjusted.It is good after each forms to be equipped with by above-mentioned volume ratio proportioning, stirs, tamping and maintenance again, finally reaches design strength.Wherein, steel ring concrete for making technology such as stirring, tamping and maintenance etc. and normal concrete, Steel Concrete are similar.
A kind of steel ring concrete according to the invention has following characteristics:
One, utilization of waste material: these steel rings are all sold salvage collection company as steel scrap with low price in iron core factory and are used for melting down steel-making; If be used for making the steel ring concrete, then belong to utilization of waste material, can increase income; Can also economize on resources, reduce the cost of manufacturer.
Two, adhesivity is good: have strict production technique when siliconized plate is rolling, surperficial oil-containing is few.During punching out, only add a spot of stamping and cutting oil, stamping and cutting oil has very strong volatility, can volatilize very soon after having dashed.So the steel ring surface does not contain greasy dirt, with concrete material good adhesive force property is arranged, not second to Steel Fiber Reinforced Concrete.
Three, tension, shearing resistance, folding strength are high: because steel ring is a kind of straight-flanked ring of sealing, in concrete can with the mutual shackles of other material, improved concrete cohesive strength greatly.The hollow ring member of the distinctive thick 0.2mm～0.5mm of steel ring is difficult for sliding at inside concrete; Can not receive behind the pulling force as Steel Fiber Reinforced Concrete mainly is that the invar fiber slides and destroys; But steel ring is broken and could be destroyed, so its tension, shearing resistance, folding strength have all improved.
Four, higher fatigue strength and impelling strength are arranged: steel ring limits the generation of infant cracking in concrete, can stop the crack to further expand under external force.At the stressed initial stage, steel ring and concrete are simultaneously stressed, and concrete is the main undertaker of external force.Along with external force constantly increases and lasting for some time, and progress of fracture is after to a certain degree, concrete stressed minimizing, and steel ring becomes the main undertaker of external force.Limit fissured further expanding greatly across fissured steel ring, thereby had higher fatigue strength and impelling strength.
A kind of steel ring concrete of the present invention, its mechanical property and normal concrete compare, and be as shown in the table:
| Tensile strength | Improve 50%～80% than normal concrete |
| Bending strength | Improve 60%～90% than normal concrete |
| Slip resistance | Improve 60%～100% than normal concrete |
| Edurance beding strength | Improve 120%～180% than normal concrete |
| Impelling strength | Improve 2～10 times than normal concrete |
| Shrinkability | Reduce by 7%～10% than normal concrete |
In view of above characteristics; The steel ring concrete is particularly suitable for bearing the bigger beam of stress in bending, post; Or bear concrete structure, and to higher engineering or a part of performance requriements such as tension, anti-folding, slip resistance and cracking resistance, shock resistance, antifatigue, antidetonation, antiknock with big tensile stress.Such as highway pavement, railroad sleeper, premculded pile, frame joint, hole, hole cover plate etc.
Concrete has bigger ultimate compression strength, but tensile strength is very low.For this reason, just in concrete, add reinforcing bar, to improve its tensile strength.And the steel ring concrete has advantages of higher tensile strength, thereby can partly replace Steel Concrete, can save expensive Twisted Steel material, reduces " carbon " content of engineering, and in this sense, the steel ring concrete also can be called green material.If in Steel Concrete, add steel ring again, then can further improve concrete intensity, lower cost.
In sum, the steel ring concrete utilizes the part waste-material-preparing, and cost is lower; Improve the comprehensive utilization ratio of steel, increased concrete kind, can expand concrete range of application; Improve its use properties; Be a kind of environmental protection type material, can effectively economize on resources, have broad application prospects.
