Abstract
The invention discloses an additive for producing steel fiber-concrete manhole covers. The additive comprises polyester type polycarboxylic acid water reducer, soap powder, welan gum, triisopropanolamine, polyether modified organic silicon foam breaker, calcium formate, synergist, and water. Through the technical scheme mentioned above, the additive can improve the early strength and mould turnover rate, reduce production cost, prevent the phenomenon of mould sticking and cover breaking, increase the glossiness of manhole cover, maintain the beautiful appearance, and enhance the mark number of manhole cover, and the produced manhole covers are completely qualified.
Description
Technical field
The present invention relates to manhole cover field, particularly relate to a kind of additive for producing fabric reinforcement concrete manhole cover.
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, in order to replace cast iron inlet for stom water double-edged fine-toothed comb and well lid, can 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 can specify there is plurality of specifications model according to requirement of engineering and standard.Present fabric reinforcement concrete manhole cover has complete design and an arrangement of reinforcement drawing, ripe production technology, shapes and die worker's unit of pinpointing and corresponding mould processing drawing, has the lectotype selection of advanced person.
The concrete grade of fabric reinforcement concrete manhole cover production and application is generally C50, owing to manufacturer mostly is workshop-based production, not strict, unlike Large Precast Members factory, such as section of jurisdiction, pile tube etc. to the quality control of concrete.The intensity of the problem so brought, mainly concrete is defective, breakage, fracture etc. easily occurs.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of additive for producing fabric reinforcement concrete manhole cover, makes the performance of manhole cover be improved.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of additive for producing fabric reinforcement concrete manhole cover, including polyesters polycarboxylate water-reducer, soap powder, welan gum, triisopropanolamine, organic silicon modified by polyether foamicide, calcium formate, synergist and water.
In a preferred embodiment of the present invention, the raw material components of described additive includes: by percentage to the quality, polyesters polycarboxylate water-reducer 10-20%, soap powder 0.5-1.0%, welan gum 0.3-0.6%, triisopropanolamine 0.2-0.5%, organic silicon modified by polyether foamicide 0.05-0.2%, calcium formate 0.1-0.3%, synergist 1.0-5.0%, water surplus.
In a preferred embodiment of the present invention, the solid content of described polyesters polycarboxylate water-reducer is 40%.
The invention has the beneficial effects as follows: the additive for producing fabric reinforcement concrete manhole cover of the present invention, early strength can be improved, mold turnover can be improved, reduce production cost, prevent sticking to mould, manhole cover damage occurs, improve the glossiness on well lid surface, guarantee attractive in appearance, promote well lid label, it is ensured that the well lid that dispatches from the factory fully meets standard-required.
