The ratio of Lime Concrete. Lime, sand, and cement mix must be combined in the proper amounts to get a good lime concrete solution. Three generally mixtures exist to make this material, but two have been discontinued as they had been found lacking in long term integrity. The only viable option is a mixture that calls for a 1:1:6 ratio—one ...
Jan 20, 2020 Lime concrete mix ratio depends on the type of construction, but in general, it can be taken up to 1:2 ratio for lime, sand respectively and up to 1:3 ratio for lime, coarse aggregate respectively. Lime concrete had wide applications in construction before the trend of using cement as binding material.
Lime Saturation Factor (LSF) The Lime Saturation Factor is a ratio of CaO to the other three main oxides. Applied to clinker, it is calculated as: LSF=CaO/(2.8SiO 2 + 1.2Al 2 O 3 + 0.65Fe 2 O 3) Often, this is referred to as a percentage and therefore multiplied by 100. The LSF controls the ratio of alite to belite in the clinker.
