The liquid percentage at 1450 0 C can be estimated using the formula. % Liquid content (1450 0C) = 3.0 x A+2.25 x F+S. Where A=Al 2 O, F=Fe 2 O 3, S= MgO+K 2 O+Na 2 O+SO 3 In Clinker. The normal range of liquid phase is 22-27%. Burnability is a reference value for raw meal indicating how difficult it is to burn.

For Malaysia, the embodied energy for 1 ton of cement is 4560 MJ/t on average and the embodied energy for 1 ton of concrete is 1000 MJ/t on average (Omar et al., 2014). It can be concluded from these numbers that the embodied energy value for 1 ton of concrete is approximately 25% of the embodied energy value for 1 ton of cement.
In 2015, 2.0 million tons of cement were produced and 2.2 million tons in 2014. CSN currently markets cement of types CP-II and CP-III, sold in the region of Baixada Fluminense, south of Rio de Janeiro, Vale do Paraíba and Grande São Paulo, in addition to the State of Minas Gerais.
