The development and application of glass fiber reinforced plastics in the construction industry is very beneficial to reducing the weight of buildings, improving the use function of buildings, reforming architectural design, speeding up construction progress, reducing project cost and improving economic benefits, and is a necessary condition for realizing the modernization of the construction industry.

1, building efficiency of FRP

(1) material performance design

The efficiency of FRP can be designed according to the use requirements. If water resistance, corrosion resistance and high strength are required, resin-based composite materials can be selected. Because of its light weight and convenient manufacture, FRP can be used to manufacture large-scale building products with complex structures and shapes at one time, thus improving the integrity of building structures.

(2) Good mechanical efficiency

The mechanical properties of FRP can be designed in a wide range. Due to different materials and different laying directions of reinforcing materials, composite materials with very different properties can be obtained. For example, the tensile strength of unidirectional glass fiber reinforced epoxy composites can reach above 1000MPa, which is higher than that of steel (construction steel). When carbon fiber is used as reinforcing material, the elastic modulus of FRP can reach the level of building steel, but its density is 4 ~ 4 less than that of steel. More importantly, in the process of manufacturing FRP, regional reinforcement can be carried out according to the stress state of the components, which can not only improve the bearing capacity of the structure, but also save materials and reduce the self-weight.

(3) Good decoration

Glass fiber reinforced plastic has a smooth surface, which can be made into various bright colors, different patterns and patterns, and is suitable for making various decorative plates, large reliefs and arts and crafts sculptures.

(4) Light transmittance

Transparent glass fiber reinforced plastic has a light transmittance of more than 85% (similar to glass), and its biggest feature is that it is not easy to break and can bear load. When used in building engineering, the structure, enclosure and lighting can be comprehensively designed, which can simplify the lighting design and reduce the project cost.

(5) thermal insulation

The function of the building is to prevent the temperature change caused by heat conduction and convection, and give people a good working and resting environment. The thermal insulation efficiency of general building materials is poor. For example, the thermal conductivity of ordinary concrete is1.5 ~ 2.1w (m k), that of red brick is 0.81w (m k), and that of resin-based composite sandwich structure is 0.05 ~ 0.08 w(m·k), which is higher than that of ordinary red brick.

(6) Sound insulation

Sound insulation effect is one of the criteria for evaluating building quality. However, among traditional materials, building materials with good sound insulation effect often have high density, poor heat insulation and difficult transportation and installation. Although the sound insulation efficiency of FRP is not ideal, it can dissipate vibration sound waves and spread sound waves. The specially designed sandwich structure can achieve the double-layer effect of sound insulation and heat insulation.

(7) Electrical efficiency

Glass fiber reinforced plastic has good insulation performance, is not affected by electromagnetic waves and does not reflect radio waves. Through this design, it can have good microwave transmission efficiency in a wide frequency band, and has special uses for buildings with electrical communication systems, such as manufacturing radomes and various computer rooms.

(8) chemical resistance

FRP has good antibacterial effect and corrosion resistance to acid, alkali, organic solvents and seawater. It is especially suitable for chemical engineering, underground engineering and water conservancy engineering.

(9) Water-permeable and water-absorbent glass fiber reinforced plastic is low in hygroscopicity and impermeable, and can be used for waterproofing and water supply and drainage of construction projects.

2. Application of building resin-based composites.

(1) bearing structure

Composite building products used as load-bearing structures include: columns, trusses, beams, foundations, load-bearing folded plates, roof panels, floors, etc. These FRP members are mainly used for chemical corrosion of load-bearing structures in factories, high-rise buildings and large plate structures of all-FRP composite buildings.

(2) envelope structure

The products of FRP enclosure structure include various corrugated plates, sandwich plates, FRP composite plates made of different materials, integral and assembled folded plate structures and shell structures. The plate used as the shell structure is not only the envelope structure, but also the load-bearing structure. These components can be used as assembly components of external wall panels, partition boards, anticorrosive floors, roof structures, sun visors, ceilings, thin shell structures and folded plate structures in industrial and civil buildings.

(3) Lighting products

Transparent building products include transparent corrugated board, translucent sandwich structure board, integral and assembled lighting cover, etc. , mainly used for lighting skylights, roofs and surrounding walls of industrial workshops, civil buildings, agricultural greenhouses and large public buildings.

(4) Door and window decoration materials

Products belonging to this kind of material include FRP doors and windows pultruded profiles, flat plates, embossed plates, composite plates and so on. Resin glass fiber reinforced plastic is used for general window frame profiles. Composite doors and windows are waterproof, heat-insulating and resistant to chemical corrosion. Used in industrial and civil buildings, decorative panels are used as dados, suspended ceilings, large reliefs, etc.

(5) Water supply and drainage engineering materials

Composite products have been widely used in municipal water supply, drainage and sewage treatment projects, such as various specifications of water supply glass steel pipes, high-level water tanks, septic tanks, anti-corrosion sewage pipes and so on.

(6) Sanitary ware materials

These products include bathtubs, washbasins, urinals, integrated and assembled toilets, etc. It is widely used in sanitary engineering of various buildings and bathrooms.

(7) Heating and ventilation materials

Composite products are cooling towers, pipes, plates, grilles, fans, blades and integral heating and ventilation products. Ventilation kitchen, air supply pipeline, exhaust pipeline and anti-corrosion hood in the central air conditioning system applied in the project.

What are the main applications of sodium silicate in architecture?

A. Brush the surface of the material with density 1.35g/cm to improve its weatherability? Soaking or brushing porous materials such as clay brick, cement concrete, silicate concrete and stone with sodium silicate can improve the compactness, strength, impermeability, frost resistance and water resistance of materials.

B, reinforcing the soil, namely alternately injecting sodium silicate and calcium chloride solution into the soil, and the generated silicic acid gel is in an expanded state due to absorbing moisture in the soil in a humid environment, so that the soil is consolidated.

C, preparing a quick-setting waterproof agent.

D. Repairing cracks in brick walls After mixing sodium silicate, granulated blast furnace slag powder, sand and sodium fluorosilicate in a proper proportion, they are directly pressed into cracks in brick walls, which can play a role in bonding and strengthening.

E, sodium silicate aqueous solution can be used as the external surface of fire doors.

F, which can be used for manufacturing acid-resistant cement and lining of furnace pits. physicochemical property

The main applications of water glass in architecture are as follows:

(1) Brush the material surface, impregnate the porous material and reinforce the foundation.

Coating the stone surface with sodium silicate can improve its weatherability and durability of buildings. At a density of 1.35g/cm? Soaking with water glass or brushing porous materials such as clay bricks and cement concrete for many times can improve the density and strength of the materials, and improve the impermeability and water resistance. However, it should be noted that gypsum products must not be treated with sodium silicate. Because the substance containing calcium sulfate reacts with water glass to generate na2so 4, Na2SO4 has crystal expansion, which will destroy the substance through crystal expansion. Water glass with modulus of 2.5-3 and calcium chloride solution are poured into the soil together, and the generated silicic acid gel is in an expanded state in a humid environment because it absorbs moisture in the soil, which consolidates the soil and improves the impermeability of the foundation.

(2) Preparation of waterproof agent

Taking water glass as the base material and adding two or four kinds of alum aqueous solutions, it is called two-alum or four-alum waterproofing agent. This waterproof agent can be mixed into portland cement mortar or concrete to improve the compactness and setting and hardening speed of mortar or concrete. Tetrasulfate waterproofing agent has a fast setting speed, generally less than 1min, and is suitable for emergency repair projects such as plugging loopholes and cracks.

(3) Sodium silicate concrete

The composite material made of sodium silicate as cementing material, sodium fluorosilicate as curing agent and powdered fillers such as cast stone powder and sand aggregate through mixing, stirring, vibrating molding, drying and curing and acidification is called sodium silicate concrete. If the filler and aggregate used are acid-resistant materials, it is called sodium silicate acid-resistant concrete; If heat-resistant sand aggregate is selected, it is called water glass heat-resistant concrete.

Sodium silicate concrete has the characteristics of high mechanical strength, good acid and heat resistance, strong integrity, wide source of materials, convenient construction, low cost and good use effect.
