Abstract
The invention discloses high-strength fiber cement and a method of manufacturing formworks by using the cement, and relates to the technical field of building material manufacturing. A composition comprises following materials by weight: 47-55 parts of Portland cement, 1-3 parts of microsilica, 2-4 parts of plant fiber, 0.5-1.5 parts of perlite, 2-3 parts of cement rubber powder, 0.4-0.8 part of water glass, 3-7 parts of mineral fiber, 22-42 parts of quartz powder and 0.5-1.5 parts of nylon powder. The high-strength fiber cement in the ratio mentioned above can be prepared into the cement building formworks in a cement mortar dehydration production line by steps of adding materials, stirring, making a blank, putting meshes, covering, discharging, and the like. The high-strength fiber cement and the method can overcome the problems of cement building formworks, namely low tensile strength, low shock strength and poor penetration resistance.
Description
Technical field
The present invention relates to material of construction manufacturing technology field, especially a kind of formula of building template taking cement as main component and make.
Background technology
Building template is the widely used a kind of temporary supporting structure of building trade, its objective is and concrete, structural part are shaped by the position specified, geometrical dimension, keep its tram, and bears building template deadweight and effect external loads thereon; Conventional building template has wooden form (comprising glued board), Sheet Steel Form and plastic mould etc., and these templates all exist some problems: one, wooden form exists the problems such as not fire-retardant, yielding, not recyclable, use cost is high; Two, Sheet Steel Form exist template from great, easily get rusty, mobile installation needs hoisting machinery handling, high in cost of production problem; Three, plastic mould exists that the little bearing capacity of intensity and toughness is low, coefficient of thermal expansion and contraction is large, electroslag welding easily scorches the problems such as template.For above various template Problems existing, oneself has people to start to make building template with cement plate in recent years, to substitute above-mentioned various template, because the building template made of cement plate does not need to remove, after concrete is dry and hard and cement building template formed integrally, a part for common formation concrete structure, building cost reduces greatly, can predict, 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! Because cement is a kind of fragility material of construction, not only tensile strength and resistance to impact shock low, and permeability resistance is also poor, if just make cement building template with cement, the overall performance of the concrete layer that the concrete of this cement formwork and its combination is formed is poor, is difficult to the requirement reaching building trade.
Summary of the invention
The object of this invention is to provide a kind of high-strength fabric cement and the method by this cement making template, the problem that it can solve cement building template tensile strength and resistance to impact shock is low, permeability resistance is poor.
In order to solve the problem, the technical solution used in the present invention is:
This high-strength fabric cement and the method by this cement making template, comprise the material of following weight part: silicate cement 47 ~ 55 parts, SILICA FUME 1 ~ 3 part, 2 ~ 4 parts, vegetable fibre, perlite 0.5 ~ 1.5 part, cement rubber powder 2 ~ 3 parts, water glass 0.4 ~ 0.8 part, mineral fibre 3 ~ 7 parts, silica powder 22 ~ 42 parts, nylon fiber 0.5 ~ 1.5 part.
Further: described SILICA FUME is 1000 order ~ 1500 object silica flours.
Further: described silica powder is 200 order ~ 500 object silica powders.
High-strength fabric cement makes a method for template, comprises the following steps:
A, to feed intake: in the head box of cement slurry dewatering production line, drop into various raw material and appropriate water that high-strength fabric cement composition comprises;
B, stirring: fully stir above-mentioned raw materials and make them mix;
C, base: by travelling belt, cement blank is attached on the excircle of forming tube through dehydration procedure on cement slurry dewatering production line;
D, to cast net: when the thickness being attached to the cement blank on forming tube reaches a half of required template thickness, throw in woven wire by the woven wire release platform be arranged in frame;
E, covering: continue cement blank to cover forming tube by travelling belt, and cover woven wire;
F, discharging: when being attached to the cement blanket thickness on forming tube and reaching setting thickness requirement, whole cement blanket is exited from forming tube.
Further: described woven 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 following beneficial effect:
1, adopt the formula of the present composition, greatly can improve tensile strength and resistance to impact shock, the permeability resistance of produced cement building template.
