Hydration is a chemical reaction that occurs between water and cement in concrete, resulting in the hardening and setting of the material. The process of hydration is what gives concrete its strength and durability. There are different types of hydration in concrete, including: Understanding the different types of hydration in concrete is important for ensuring the proper handling and curing […]
Type II GGBS, or Ground Granulated Blast Furnace Slag, is another type of supplementary cementitious material used in concrete. It is also known as low heat GGBS because it generates less heat during the hydration process compared to other types of GGBS. The purpose of Type II GGBS in concrete is similar to that of Type I GGBS, which is […]
Type I GGBS, or Ground Granulated Blast Furnace Slag, is a type of supplementary cementitious material used in concrete. It is the most commonly used type of GGBS in concrete and is suitable for use in all types of concrete. The purpose of Type I GGBS in concrete is to replace a portion of the Portland cement in the mix. […]
GGBS, or Ground Granulated Blast Furnace Slag, is a byproduct of the iron and steel industry that is used as a supplementary cementitious material in concrete. GGBS is produced by quenching molten slag from a blast furnace with water and then grinding the resulting material into a fine powder. This process creates a material with cementitious properties that can be […]
Cured-in-Place GRP lining (CIPP) is a process used to create a Glass Reinforced Plastic (GRP) lining for the interior of a pipeline or other cylindrical structure. This process involves the insertion of a flexible, resin-impregnated liner into the pipeline, which is then inflated and cured to create a new, structurally sound lining. The purpose of Cured-in-Place GRP lining is to […]
Prefabricated GRP lining is a process in which a Glass Reinforced Plastic (GRP) lining is fabricated in a factory or workshop and then transported to the site where it is to be installed. This process involves creating a lining to exact specifications and then transporting it to the site where it is installed, reducing the need for on-site fabrication. The […]
Filament Winding GRP Lining is a process used to create a Glass Reinforced Plastic (GRP) lining for the interior of a structure or container. This process involves winding continuous fibers of fiberglass around a rotating mandrel, which is then coated with resin to form the lining. The purpose of Filament Winding GRP Lining is to create a strong, durable, and […]
Spray-Up GRP Lining is a process used to create a Glass Reinforced Plastic (GRP) lining for the interior of a structure or container. This process involves spraying a mixture of resin and chopped fiberglass onto the surface to be lined using a spray gun. The purpose of Spray-Up GRP Lining is to create a smooth, durable, and corrosion-resistant surface on […]
Hand Lay-Up GRP Lining is a process used to create a Glass Reinforced Plastic (GRP) lining for the interior of a structure or container. This process involves manually applying layers of resin and fiberglass to the surface to be lined using brushes and rollers. The purpose of Hand Lay-Up GRP Lining is to create a smooth, durable, and corrosion-resistant surface […]
GRP lining is the process of using Glass Reinforced Plastic (GRP), also known as Fiberglass, to line the interior of a structure or container. This lining is used to protect against corrosion and to provide a smooth, durable surface that is easy to clean and maintain. There are several different types of GRP lining, including: Each type of GRP lining […]
