Hydraulic lime
Encyclopedia : H : HY : HYD : Hydraulic lime
Hydraulic lime is a variety of slaked lime used to make mortar. It is produced by heating (calcining) limestone that contains clay and other impurities that enable it to set without exposure to air. It is used for providing a faster initial set in more extreme conditions (including under water).
Lime in Construction
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", Lime is a natural material, It has a low embodied energy which means it has a lower firing temperature, Brickwork bonded with lime is easier to re-use, It is less dense than cement, thus, less cold bridging, Lime re-absorbs CO 2.
