Hydraulic Lime

HYDRAULIC LIME IN CONSTRUCTION

Hydraulic lime is a useful building material for the following reasons;

It has a low modulus of elasticity,

There is no need for movement joints,

It allows buildings to "breathe",

It has a lower firing temperature than Portland Cement , and produces less CO₂ than ordinary lime, and so is less polluting,

Brickwork bonded with lime is easier to re-use,

It is less dense than cement, thus less cold bridging,

Lime re-absorbs CO₂, thus partially offsetting the large amount emitted during its manufacture.
