1. What are
the limitations of Lime as a cementing material?
a. The cementing bond of lime is not as
strong as that of Portland cement. However, before the advent of cement, lime
was the only material used in construction as a cementing material.
b. Lime takes a longer time to set since
it has to depend upon the availability of CO2 from the nature. Due to this the
speed of construction is restricted. For constructing a wall, after every .75
meter height, we may have to wait for 8 days to build it further.
c. Lime plaster / mortar can get eroded /
damaged due to heavy rains or turbulent wind blasts.
d. Lime is not a ready to use product like
cement. It needs slaking and other preparations before use.
e. Tiles fitted with lime get bulged out
after an year or so. This is due to the temperature variations evolving gases
like CO2.
Only heavy flooring like marble or other stone slabs can withstand these gas
pressures.
