GGBS slag is by product of iron and steel manufacturing process. It contains the entire basic constituent of OPC but not exactly in the same ratio and chemical form. Slag itself has no cementing property but when mixed with OPC, it develops hydraulic properties similar to cement.

Chemical Composition Of GGBS The chemical composition of a slag varies considerably depending on the composition of the raw materials in the iron production process. Silicate and aluminate impurities from the ore and coke are combined in the blast furnace with a flux which lowers the viscosity of the slag.

GGBS is a glassy, granular, non metallic material consisting essentially of silicates and aluminates of calcium and other bases. Slag when ground to less than 45 micron from coarser, popcorn like friable structure, will have a specific surface of about 400 to 600 m2/kg (Blaine). GGBS has almost the same particle size as cement.

Chaeng GGBS production line has been recognized by key customers, the domestic production operation of the production line has been up to more than 30, customers all over the country. Process Description. The stacked slag is packed and feed by the forklift trucks, then transported by belt conveyor.

Because GGBS has low embodied CO 2, it allows designing concrete mixes for sustainable construction. The manufacture of GGBS requires less than 20% of the energy and produces less than 10% of the CO 2 emissions compared to Portland Cement production. GGBS is a sustainable alternative for Portland Cement in the production of: ready-mix concrete.

The process involves cooling of the slag through high-pressure water jets, this leads to formation of granular particles. The granulated slag is further processed by drying and then grinding in a vertical roller mill or rotating ball mill or roller press to a very fine powder,which is called GGBS.

slag is rapidly quenched in water. This process is known as granulation because it produces glassy granules, similar in appearance to a coarse sand. These have excellent cementitious properties. The hydration process GGBS can be used as a replacement for cement because the hydration process is similar to that of Portland cement.

In this step, the materials, energy and waste flows involved in the production process will be converted to flow elementary. The databases for OPC, sand and electricity production represent the local Malaysian local flow elementary, while built-in Ecoinvent database was used for the water and GGBS production process.

• Sources of GGBS not readily available in Hong Kong. i.e. Hong Kong. not economical to import blast import furnace slag from steel mill. • Current specification not cater to adopt the use of blast furnace slag as substitution. • In UK current demand for ggbs exceeds its production by approx. 50%, i.e. needs

GGBS slag is a derivative from the manufacturing process of iron and steel. It contains the entire basic constituents of Ordinary Portland Cement (OPC) but in a different percentage and chemical formula. Slag does not has any innate cementing ability; however, when combined with OPC, it produces hydraulic capability identical to cement.

It is economical in large quantities, so it is suitable for premixed concrete, bulk on-site concrete production, and precast product manufacturing (Samad et al., 2017). GGBS produces lower heat during the hydration process, enhances resistance from chloride and sulfate attack compared with OPC.
