Home thesis grind kaolin replacement with cement

the discussion of cement in this thesis is mainly about the Portland cement. Portland cement, the basic ingredient of concrete, is a closely controlled chemical combination of calcium, silicon, aluminum, iron, and small amounts of other ingredients to which gypsum is added in the final grinding process to regulate the setting time of concrete.

Concrete is made by mixing cement with water and aggregate. Usually, the aggregate consists of stones or rocks, but MPB wood is a new option. "Normally, cement repels organic materials, such as wood," says Pasca, who recently completed his master's degree at UNBC by researching this topic. "But for some reason, cement sticks to ...


The production of Portland cement (PC) is the major source of CO 2 emissions associated with concrete materials. Due to the very large volumes of cementitious materials used (around 50% or all manufactured materials), it is estimated to be responsible for 6–8% of global anthropogenic greenhouse gas emissions [1, 2].This originates mainly from decomposition of …

The raw material in the manufacture of Metakaolin is kaolin clay. Heating up of clay with kaolinite (Al2O3.2SiO2.2H2O) as the basic mineral component to the temperature of 500 °C – 600°C causes loss of structural water with the result of deformation of crystalline structure of kaolinite and formation of an unhydrated reactive form so-called metakaolinite.
