Introduction to the production process of GRC

Glass fiber reinforced concrete is a fiber concrete composite material with alkali-resistant glass fiber as the reinforcement and cement mortar as the matrix material. GRC is a material that expresses the designer's imagination through mold shape, texture, texture, and color. Below I will introduce you to the GRC process.

A brief introduction to the production process

There are many types of glass fiber reinforced concrete, such as short-cut fiber yarn, continuous fiber untwisted roving, mesh cloth, short-cut fiber mat, etc. Different types of glass fiber are mixed into the cement matrix in different ways, and the same type of glass fiber is not mixed into the cement matrix in the same way. Moreover, the amount of glass fiber incorporated and the way of use has a great influence on the mechanical properties of glass fiber reinforced cement composites.

This has resulted in a variety of processes for making glass fiber reinforced concrete, such as injection process, premixed injection process, premixed casting process, injection molding process, cloth mesh process, winding process, etc. Each of these production processes has its advantages and disadvantages. Each production process has its characteristics and is suitable for making different products, and of course, the equipment used is also different.

Specific production process

1、Jetting process

The spraying process is the earliest and most applied method of manufacturing GRC facades, including manual spraying and automatic spraying. Early 1970s BRE was the first to use this method to manufacture glass fiber reinforced concrete (GRC) products.

Whether hand blasting or mechanical blasting, the blasting process requires specially trained operators and specialized equipment. The correct method of operation greatly affects the strength and durability of GRC concrete. For the injection process, the glass fiber is randomly distributed in the cement mortar in a two-dimensional chaotic direction, the effective utilization rate of the fiber is high, and the physical properties of the products are better.

2、Pre-mixing process

The pre-mixing process is to mix short-cut glass fiber and cement mortar matrix to form a homogeneous glass fiber cement mixture and then made it by pouring or spraying method. According to the different molding methods, the premixed process can be divided into the premixed casting process and premixed injection process. The premixed casting process is similar to the process for precast concrete products, where the casting process is often supplemented by a vibratory process.

Over the last 24 years, our production process has been updated with the advancement of technology. We started to use 3Dscanning, 3D sculpture, 3D printers, etc., to precise position the sculpture processing and installation, and high-end digital production guarantee. It is the responsibility of every manufacturer to produce GRC decoration that meets the standards to ensure the healthy development of the supply cable market. Our company has conducted several tests on our products before leaving the factory, and the quality pass rate is guaranteed. If you need to buy GRC, you can consider our cost-effective products.
