 — The SEM-analyses demonstrate the influence of the burning temperature. The sample burnt at 1’050 C shows particles with a very porous structure typical for soft burnt, high reactive lime. When looking at the sample burnt at 1’450 C larger crystals can be detected. This indicates the presence of mass transport on the surface and re ...

with water creating hydrated lime and releasing large amounts of heat. Hydrated lime is calcium hydroxide (Ca(OH) 2). This is a very fast acting and powdery lime material. This material is caustic and can easily burn plants that are already established. Finely ground hydrated lime can have an ENV of 120-135% and if too much is applied the soil pH

 — The earliest use of lime dates to present-day Turkey between 7,000 and 14,000 years ago, and many ancient civilisations used it to create mortar between stones. The Romans, however, took lime a step further, mixing it with various other ingredients to create an early version of cement.

 — The early strength of both soft- and hard-burn AAB pastes increased as SS/SH increases, from 3.56 to 10.10 MPa for the soft-burn type and 0.55–0.79 MPa for the hard-burn type. The higher SS/SH provided more silica into the system and enhanced the binders' reactions.

 — The classification of lime is often seen in terms of its reactivity, such as (i) dead burned, (ii) hard, (iii) medium, and (iv) soft. Lime with a lower reactivity is often referred to as medium, hard and dead burned. The decrease of reactivity is accompanied by a reduction of the surface and the porosity of the lime, which is called sintering.
