FES Journal of Engineering Sciences, 2021 The standard mix ratio of lime: pozzolana specified by all standards is 1:2 by weight to produce lime pozzolan cement (LPC) with the minimum required strength of 4 MPa. This ratio may be affected by many factors such as the quality of lime and pozzolana, in adition to the quantity of amorphous silica in pozzolana.
