Abstract
The invention discloses a kind of high-strength fabric cement and the method making template with this cement, relate to construction material manufacturing technology field；Said composition includes the material of following weight portion: portland cement 47 ~ 55 parts, SILICA FUME 1 ~ 3 part, Plant fiber 2 ~ 4 parts, perlite 0.5 ~ 1.5 part, cement rubber powder 2 ~ 3 parts, waterglass 0.4 ~ 0.8 part, mineral fibres 3 ~ 7 parts, silica flour 22 ~ 42 parts, nylon fiber 0.5 ~ 1.5 part；By the high-strength fabric cement of above-mentioned weight on cement slurry dewatering production line through feeding intake, stirring, base, cast net, cover, the operation such as discharging can be prepared by required cement building template；The present invention can solve cement building template tensile strength and impact strength is low, permeability resistance is poor problem.
Description
Technical field
The present invention relates to construction material manufacturing technology field, the formula of especially a kind of building template made with cement for main component.
Background technology
Building template is the widely used a kind of temporary supporting structure of building trade, its objective is to make concrete, structural member shape by the position of regulation, physical dimension, keeps its tram, and bear building template deadweight and act on external loads thereon；Conventional building template has plank sheathing (including plywood), steel form and plastic formwork etc., and these templates all exist some problems: one, plank sheathing exists the problems such as not fire-retardant, yielding, not recyclable, use cost is high；Two, steel form exist template from great, easily get rusty, mobile installation needs hoisting machinery handling, high in cost of production problem；Three, plastic formwork exists that the little bearing capacity of intensity and toughness is low, coefficient of thermal expansion and contraction is big, electroslag welding easily scorches the problems such as template.For any of the above template Problems existing, oneself has people to start to make building template with cement plate in recent years, to substitute above-mentioned various template, owing to the building template made of cement plate need not be removed, formed integrally with cement building template after concrete is dry and hard, collectively form a part for xoncrete structure, building cost is substantially reduced, it is contemplated that in the near future, this cement building template will replace above-mentioned various template in a large number, become the main force of building template！Owing to cement is a kind of fragility construction material, not only tensile strength and impact strength are low, and permeability resistance is also poor, if simply making cement building template with cement, the overall performance of the concrete layer of the concrete formation that this cement formwork is in connection is poor, it is difficult to reach the requirement of building trade.
Summary of the invention
It is an object of the invention to provide a kind of high-strength fabric cement and the method making template with this cement, it can solve cement building template tensile strength and impact strength is low, permeability resistance is poor problem.
In order to solve the problems referred to above, the technical solution used in the present invention is:
This high-strength fabric cement and the method making template with this cement, including the material of following weight portion: portland cement 47 ~ 55 parts, SILICA FUME 1 ~ 3 part, Plant fiber 2 ~ 4 parts, perlite 0.5 ~ 1.5 part, cement rubber powder 2 ~ 3 parts, waterglass 0.4 ~ 0.8 part, mineral fibres 3 ~ 7 parts, silica flour 22 ~ 42 parts, nylon fiber 0.5 ~ 1.5 part.
Further: described SILICA FUME is the silica flour of 1000 order ~ 1500 orders.
Further: described silica flour is the silica flour of 200 order ~ 500 orders.
A kind of high-strength fabric cement makes the method for template, comprises the following steps:
A, feed intake: in the head box of cement slurry dewatering production line, put into various raw materials and appropriate water that high-strength fabric cement compositions comprises；
B, stirring: be sufficiently stirred for above-mentioned raw materials and make they mix homogeneously；
C, base: by conveyer belt, cement blank is attached on the excircle of forming tube through dehydration procedure on cement slurry dewatering production line；
D, cast net: when the thickness of the cement blank being attached on forming tube reaches the half of required template thickness, throw in steel wire by the steel wire release platform being arranged in frame；
E, covering: continue by conveyer belt, cement blank is covered forming tube, and cover steel wire；
F, discharging: when the cement blanket thickness being attached on forming tube reaches to set thickness requirement, whole cement blanket is exited from forming tube.
Further: described steel wire steel wire diameter is 1mm ~ 2mm, mesh 40mm ~ 60mm × 40mm ~ 60mm.
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that
1, the formula of the present composition is adopted, it is possible to be greatly improved tensile strength and impact strength, the permeability resistance of produced cement building template.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is further described:
