Surkhi is a very ancient building material. In many parts of India, the use of lime and surkhi is a common practice. It is because Surkhi bonds well with lime and helps in the carbonation of lime. Many monuments, temples, forts, haveli, and traditional homes use surkhi with lime for mortars and plasters. Other aggregates and admixtures are also present in such mixes, but the bond between surkhi and lime is exceptional. Surkhi is porous and can retain moisture, which can help in the early carbonation of lime. It is identified long ago and is a crucial factor in the traditional system. Fun Fact: Even the modern material innovations in cement are also trying to use surkhi (or other pozzolanic material) as an ingredient for cement to make it less disastrous to the environment (read more about LC3 cement). So, the question is, if it is such excellent material, then why should we not learn about the old, time-tested combination of lime and surkhi and make good, sustainable homes to meet our needs?
