Compressive strength and SEM analysis were conducted on the geopolymeric powder and the resulted geopolymer paste. Kaolin used in this work was obtained from Associated Kaolin Industries Sdn. Bhd, Malaysia with minimum 40% particle size with less than 2µm. Calcined kaolin was prepared by thermal treatment at 800 °C for 2 hours in furnace.
Kaolin and bauxite presented cold strengths of 27MN/m2 and 17MN/m2, respectively. This showed that kaolin has more cold crushing strength than bauxite as an individual raw refractory material. Cold crushing strength for 2:7 ratio was 22MN/m2 which increased to 33MN/m2 as kaolin increased to 7:2.

Kaolin is used in many consumer products and as a functional additive and process enabler in manufacturing. It is typically extracted from open-pit mines that range from small to very large scale (tens to hundreds of thousands of dry metric tons produced per year). Ore processing consists of removing impurities, engineering particle size and ...
Kaolin is the deposit of naturally occurring minerals containing hydrated aluminum silicates. Widely known as white clay or china clay, these minerals have desirable properties crucial for industrial and commercial applications.For that reason, the kaolin mining and processing steps thoroughly put the nature of the crude deposits and the end …
