ShengFanjc GFRC Introduction

ShengFanjc GRC Introduction Chinese full name :Glass fiber reinforced cement composites English name :Glass fiber reinforced cement composites GRC(GFRC) Is the abbreviation of glass fiber reinforced cement composite material ,From the European and American technology, is the anti-alkali glass fiber, cement, sand and other composite materials according to a certain ratio of mixing, in the mold within the molding, to produce a rich shape, texture and diverse products, are widely used at home and abroad have their own characteristics In the building. GRC's cementitious material is cement, so GRC is also a concrete product, belonging to a branch of the concrete industry.Ordinary concrete compressive strength is high, but the bending strength, tensile strength and impact strength is low.GRC due to its incorporation of alkali-resistant glass fiber, making its performance in all aspects of the above compared to ordinary concrete has a qualitative leap, without reducing the advantages of concrete products in the case of GRC material significantly increased the cement products Bending strength, tensile strength, impact strength and reduce their own density. High-quality GRC products can reach the bending strength of 25Mpa, impact strength of 10-25KJ / m2, but its dry density of only 1800-2000kg / m3, lighter than the concrete products about 1/5.These features make the GRC a significant advantage over prefabricated concrete or other cement products, especially when a thin-walled material is required, the advantages of b

Shengfan GFRG installation process

.GRG(GFRG) ceiling installation Ceiling installation mainly through the screw connection, the screw is not less than 8 cm, but the screw connection should not be too high, if the ceiling finish and floor height of more than 1 meter, and finally another welding conversion layer, the height of the layer if more than 2 meters, Double steel frame, steel frame conversion layer must take into account the space span, the span of the conversion layer should be increased to increase the steel model to reduce the sag index.After the conversion layer is best to put a few days after the time, so that the natural sagging steel in place after the GRG installation.When installing the ceiling GRG, the level of the middle part of the ceiling can be adjusted to about 5mm according to the experience value. After the GRG plate is installed, the steel frame will fall again after the steel plate, but the coefficient is not big, so it is solved by raising the middle level.As the GRG characteristics of the variable type, and the elasticity is better, so the installed GRG plate must be connected with a screw. .Wall mounting (same as GRC dry installation) .Seam processing : 1. Cracked paste deployment: Rafa caulking plaster + staple fiber (glass fiber) + retarder + water

Application scope of GFRG new materials

Glass Fiber Reinforced Gypsum (GFRG or GRG) is a white 'thin cast' alpha gypsum that is field finished, or may be factory finished depending on the specific application. Where once traditional 'plaster castings' were used, Glass Fiber Reinforced Gypsum (GFRG or GRG) is now specified because of its lightweight, superior strength and ease of installation. Glass Fiber Reinforced Gypsum (GFRG or GRG) is a white 'thin cast' alpha gypsum that is field finished, or may be factory finished depending on the specific application. Where once traditional 'plaster castings' were used, Glass Fiber Reinforced Gypsum (GFRG or GRG) is now specified because of its lightweight, superior strength and ease of installation. Glass Fiber Reinforced Gypsum (GFRG or GRG) is the bridge to shapes and curves for the drywall/plasterboard trades. With the move away from "less is more" in the late 1970's and the re-introduction of traditional architectural forms, GFRG (or GRG) evolved as the ideal medium. The construction boom of the past four decades established Glass Fiber Reinforced Gypsum as the means for architects and designers to achieve their design visions, while leveraging the experience of regular building trades. Today, Glass Fiber Reinforced Gypsum is used to achieve modern and "organic" shapes on walls and ceiling, in addition to traditional architectu

UHPC: A Robust Solution for Highway Infrastructure

Advances in the science of concrete materials have led to the development of a new class of cementitious composites called ultra-high performance concrete (UHPC). The links above will direct you to pages detailing UHPC projects, bridges with UHPC components, articles that focus on UHPC research, and the main contact at Turner-Fairbank Highway Research Center (TFHRC) for UHPC. The mechanical and durability properties of UHPC make it an ideal candidate for use in developing new solutions to pressing concerns about highway infrastructure deterioration, repair, and replacement. Since 2000, when UHPC became commercially available in the United States, a series of research projects has demonstrated the capabilities of the material. A handful of State departments of transportation have deployed UHPC components within their infrastructure, and many more are actively considering the use of UHPC. UHPC is a cementitious composite material composed of an optimized gradation of granular constituents, a water-to-cementitious materials ratio less than 0.25, and a high percentage of discontinuous internal fiber reinforcement. The mechanical properties of UHPC include compressive strength greater than 21.7 kilopounds per square inch (ksi) (150 Megapascals (MPa)) and sustained postcracking tensile strength greater than 0.72 ksi (5 MPa). Ultra-high performance concrete has a discontinuous pore structure that reduces liquid ingress, significantly enhancing durability compared to conventional and high-performance concretes. UHPC is being considered for use i

UHPC REINVENT STEEL, REIMAGINE CONCRETE

Ultra High Performance Concrete (UHPC) is a fiber reinforced cementitious composite which has garnered widespread interest since its inception in the 1990s. Various barriers to market have been slowly overcome. It is now commonly applied as a connection material for precast elements in many bridge deck replacements as well as in new construction applications. At Precast Systems Engineering, we are imagining new uses for UHPC as a component in the bridge and marine construction applications as formwork and integral precast systems capable of meeting the challenges ahead in challenging environments.
