Different Types of Fiber-Reinforced Ready-Mix Plaster and Their Applications
(1)How is it manufactured?
The manufacturing process of Glass Fiber Reinforced Plaster (GFRP) primarily involves effectively combining glass fibers with gypsum matrix materials to enhance the mechanical and application properties of the gypsum. Below is a detailed explanation of the manufacturing methods for glass fiber reinforced gypsum:
1.Dispersion Methods of Glass Fibers in Gypsum
The distribution of glass fibers within the gypsum matrix is crucial for its reinforcement effectiveness, typically involving the following three dispersion methods:
One-Dimensional Orientation: Glass fibers are oriented in a specific direction within the gypsum matrix. To fully utilize the reinforcing effect, fibers should be positioned in both the upper and lower layers of the fiber gypsum board. To prevent layering in the gypsum products, it is essential that the fiber bundles are thoroughly saturated with the gypsum slurry.
Two-Dimensional Plane Distribution: A network of glass fibers is laid in the upper and lower layers of the gypsum board. However, this method may lead to significant layering issues, resulting in suboptimal interfacial bonding and a noticeable decrease in strength.
Three-Dimensional Random Distribution: Short-cut glass fibers are added to the gypsum matrix during molding. This method requires simple equipment and is easy to operate, making it a commonly used reinforcement approach today. However, its drawbacks include uneven distribution, breakage, and clumping of glass fibers. If appropriate lengths and dosages of glass fibers are used, these issues can be effectively mitigated.
2.Manufacturing Steps
Raw Material Preparation:Gather high-strength gypsum powder, short-cut glass fibers, water, and any necessary additives (such as retarders or accelerators).
Mixing: Combine the gypsum powder, short-cut glass fibers, and water in a mixer according to specified proportions. During mixing, ensure that the glass fibers are evenly dispersed within the gypsum matrix to maximize their reinforcing effect.
Molding: Pour the mixed glass fiber reinforced gypsum into molds and use vibration or compaction techniques to eliminate air bubbles and ensure material density.
Curing: The molded glass fiber reinforced gypsum must be cured under appropriate conditions to allow for complete hydration of the gypsum and achieve the desired strength.
3.Reinforcement Mechanism of Glass Fibers
The reinforcement effect of glass fibers in the gypsum matrix is primarily reflected in several aspects:
Increased Flexural Strength: Glass fibers possess high tensile strength and fracture toughness, allowing them to absorb significant energy when forces are applied to the gypsum matrix, thereby inhibiting crack formation and propagation and improving flexural strength.
Improved Water Resistance: While adding glass fibers may impact the water resistance of gypsum, proper formulation and surface treatment can mitigate this issue to some extent.
Enhanced Durability: Glass fibers exhibit good chemical stability and are less affected by environmental changes, thus enhancing the durability of gypsum products.
4.Application Areas
Due to its lightweight nature, fire resistance, sound insulation properties, environmental friendliness, and ease of construction, glass fiber reinforced gypsum is widely used across various construction fields. It provides safer and more reliable support for commercial buildings, public structures, and residential projects while enhancing overall building quality and comfort.
In summary, the manufacturing process of glass fiber reinforced gypsum requires strict control over raw material ratios and mixing techniques to ensure uniform dispersion of glass fibers within the gypsum matrix for effective reinforcement.

Moreover, the versatility and plasticity of fiber-reinforced premixed gypsum have earned it widespread recognition in the decorative materials field. From exquisite sculptures to practical interior decorative items, it easily adapts to various designs, providing designers and artists with limitless creative space. Additionally, its good sound absorption properties make it a preferred material for special venues like theaters and concert halls.
It is worth noting that the advantages of fiber-reinforced premixed gypsum extend beyond these aspects. It also features excellent fireproofing and waterproofing capabilities while being environmentally friendly and energy-efficient. Its production and usage have minimal environmental impact, aligning with modern construction’s pursuit of sustainability. Furthermore, its convenient construction characteristics and efficient processing significantly enhance building efficiency while reducing construction costs.
In summary, fiber-reinforced premixed gypsum plays an increasingly important role in the construction and decoration industries due to its unique properties and wide range of applications.
