It is a won­der­ful bind­ing and strength­en­ing build­ing ma­te­rial, and was once widely used across the coun­try. Its cli­matic re­spon­sive­ness and ad­van­tage, right from em­bod­ied en­ergy to heat trans­fer and longevity, in trop­i­cal In­dia are ex­pe­ri­enced both by layper­sons and tech­ni­cal experts. But it has failed to com­pete with its vi­cious com­peti­tor—ce­ment. The fact is that the ce­ment in­dus­try gets tremen­dous sup­port from the govern­ment, right from procur­ing raw ma­te­rial, to sourc­ing en­ergy, wa­ter and land. As a re­sult, the highly sub­sidised read­ily us­able ce­ment bag is eas­ily avail­able to a con­sumer com­pared to lime, which is dif­fi­cult to source. This has prompted builders to opt for ce­ment over lime for ba­sic con­struc­tion. The use of lime over ce­ment in var­i­ous com­po­nents, such as lime-mor­tar, lime-plas­ter and screed, would pro­pel a build­ing to­wards being green.
