This is 400 m 3 (524 yd 3) of gas; and CO 2 normally forms only 0.04% of air. Cement production is responsible for around 7% of worldwide greenhouse gas emissions. The only larger contributors are electricity generation and transport. Most of the CO 2 released when cement is made comes from the chemical reaction.

What Are the Mix Ratios for Cement and Sand?

Aug 04, 2015 The basic mix ratio for concrete is one part water, two parts cement and three parts sand. An alternative ratio is one part cement, two parts sand and three parts gravel with enough water added until the mixtures reaches the consistency of thick mud. Lime is also a common additive to the mix.

Silica Ratio (SR) The Silica Ratio (also known as the Silica Modulus) is defined as: SR = SiO 2 /(Al 2 O 3 + Fe 2 O 3) A high silica ratio means that more calcium silicates are present in the clinker and less aluminate and ferrite. SR is typically between 2.0 and 3.0. Alumina Ratio (AR) The alumina ratio is defined as: AR=(Al 2 O 3 /(Fe 2 O 3)
