ACI 549.5R-16 PDF Download

ACI 549.5R-16 is a standard report that provides comprehensive information on the use of spray-up and continuous strand techniques in the production of glass fiber-reinforced concrete (GFRC). The report highlights the various processes involved in manufacturing GFRC using these techniques and discusses the properties and applications of the resulting products.

The spray-up process involves the use of a spray gun to deposit a mixture of GFRC matrix and glass fibers onto a mold or substrate. This technique is known for its ability to produce complex shapes and intricate designs with minimal labor and material waste. The report explores the materials, equipment, and techniques used in the spray-up process, as well as the effects of various parameters on the final product's properties.

On the other hand, the report also covers the continuous strand technique, which utilizes continuous glass fiber strands embedded in the GFRC matrix. This technique offers increased strength and durability compared to the spray-up process and is often used in applications that require high-performance GFRC products. The report provides insights into the manufacturing process, including the types of fibers and matrix materials used, as well as the various methods of reinforcing the continuous strands.

Additionally, the report discusses the properties and performance characteristics of GFRC produced using both techniques. It touches on durability, strength, toughness, moisture resistance, dimensional stability, and fire resistance, highlighting the advantages and limitations of each technique.
