Abstract
The invention discloses concrete for a plastic mold to produce a steel fiber concrete well seat. The concrete comprises cement, yellow sand, cobblestone, steel fiber, coal ash, silica fume, water reducer, polyether modified organosilicon defoamer, thickener, early strength agent and water. By the above mode, chemical additives are adopted to modify the concrete and to optimize matching ratio of the same, so that early strength of the concrete is improved, demolding quality is improved, and production efficiency is improved.
Description
Technical field
The present invention relates to a kind of concrete, particularly relate to a kind of concrete producing steel fiber reinforced concrete well seat for mould of plastics.
Background technology
Fabric reinforcement concrete manhole cover, it is using steel fiber reinforced concrete as matrix, utilizes the shock resistance of steel fiber reinforced concrete, anti-fatigue performance and steel fiber reinforced concrete to tend to the feature of Two dimensional Distribution in thin-wall member, and be equipped with suitable reinforcing bar, strengthen frame with band iron, meticulously process.
Fabric reinforcement concrete manhole cover is in order to replace cast iron inlet for stom water double-edged fine-toothed comb and well lid, it is possible to alleviate construction weight nearly 30%, reduces cost about 50%, can meet the requirement of loaded vehicle load, and effectively solve loss problem.Fabric reinforcement concrete manhole cover specifies there is plurality of specifications model according to requirement of engineering and standard.Present fabric reinforcement concrete manhole cover has complete design and arrangement of reinforcement drawing, ripe production technology, die worker's unit of sizing and fixed point and corresponding mould processing drawing, has the lectotype selection of advanced person.
Steel fiber reinforced concrete well seat is when using mould of plastics to produce, different from adopting punching block.Difference is in that, adopt mould of plastics, steel fibre dispersion effect in concrete is bad, and in concrete during vibration, cut is easily caused to mould of plastics in its two ends, so that concrete mortar can be added in cut, when molding next time, novel concrete can embed, and is firmly bonded, it is not easy the demoulding, adopts external force forced demoulding then can cause the breakage of well seat, fracture.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of concrete producing steel fiber reinforced concrete well seat for mould of plastics, the easy demoulding, is conducive to producing.
For solving above-mentioned technical problem, the technical scheme that the present invention adopts is: provide a kind of concrete producing steel fiber reinforced concrete well seat for mould of plastics, including cement, yellow ground, stone, steel fibre, flyash, silicon ash, water reducer, Polyether Modified Polysiloxanes Defoaming Agent, thickening agent, early strength agent and water.
In a preferred embodiment of the present invention, the component that described concrete raw material includes has: in parts by weight, cement 400-600 part, yellow ground 700-900 part, stone 800-1200 part, steel fibre 3-6 part, flyash 10-20 part, silicon ash 10-30 part, water reducer 3-5 part, Polyether Modified Polysiloxanes Defoaming Agent 1-3 part, thickening agent 5-10 part, early strength agent 1-2 part, water 280-550 part.
In a preferred embodiment of the present invention, described cement is cement PO42.5；Described yellow sand is two district's medium sands, and the modulus of fineness of described yellow sand is 2.6-2.9, and the clay content of described yellow sand is less than 1.0%；Described stone is particle diameter is the continuous grading of 5mm-20mm.
In a preferred embodiment of the present invention, described steel fibre is blunt nosed steel fibre；Described flyash is I grade of flyash；The water-reducing rate of described water reducer is more than 30%.
The invention has the beneficial effects as follows: the concrete producing steel fiber reinforced concrete well seat for mould of plastics of the present invention, adopt chemical addition agent that concrete is modified, the match ratio of optimised coagulation soil, improves epistasis concrete morning, promote demoulding quality, improve production efficiency.
