Using lime as a construction material

It has a low elastic modulus. There is no need for expansion movement joints.

Using lime as a construction material

These materials were used because of availability and low cost. The Egyptians utilized gypsum mortars to lubricate the beds of large stones when they were being moved into position ref. However, these matrials did not perform well in the presence of high levels of humidity and water.

It was discovered that limestone, when burnt and combined with water, produced a material that would harden with age. The earliest documented use of lime as a construction material was approximately B.

The beginning of the use of lime in mortars is not clear. It is well documented, however, that the Roman Empire used lime based mortars extensively.

Using lime as a construction material

Vitruvius, a Roman architect, provided basic guidelines for lime mortar mixes ref. For in this way there will be the right proportion of the mixture and blending. The Romans created hydraulic mortars that contained lime and a pozzolan such as brick dust or volcanic ash.

These mortars were intended be used in applications where the presence of water would not allow the mortar to carbonate properly ref. Examples of these types of applications included cisterns, fish-ponds, and aqueducts.

The most significant developments in the use of pozzolans in mortars occurred in the 18th century.


It was discovered that burning limestone containing clays would produce a hydraulic product. InJames Smeaton developed perhaps the first hydraulic lime product by calcining Blue Lias limestone containing clay. An Italian pozzolanic earth from Civita Vecchia was also added to provide additional strength ref.

This mortar mixture was used to build the Eddystone Lighthouse. James Parker patented a product called Roman cement or natural cement in Natural cement was produced by burning a mixture of limestone and clay together in kilns similar to those used for lime. The resulting product was ground and stored in waterproof containers.

Typically, natural cements had higher clay contents than hydraulic lime products, which allowed for better strength development.

Using lime as a construction material

Natural cement mortar was used in construction where masonry was subjected to moisture and high levels of strength were needed ref. Portland cement consisted of a blend of limestone, clay and other minerals in carefully controlled proportions which were calcined and ground into fine particles.

Though some portland cement was imported from Europe, it was not manufactured in the United States until A guide by Cornish Lime, using NHL or Lime Putty.

There are a number of different substrates you could be working with, from a simple masonry wall to a timber lath substrate, and we have tried to keep the following guide as generic as possible. Using Hemp in Construction It is created by wet-mixing the chopped woody stem of the hemp plant (hemp shiv) with a lime-based binder to create a material that can be cast into moulds.

Lime is a material comprising any physical and chemical forms under which calcium and/or magnesium oxide (CaO and MgO) and/or hydroxide (Ca. Drying Soils Chemically Using Lime. Contractors should review the material safety data sheet before beginning lime application.

The National Lime Association also has several publications available on their website that offers helpful guidance on using lime in construction.

The earliest documented use of lime as a construction material was approximately B.C. when it was used in Egypt for plastering the pyramids(ref. ii). The beginning of the use of lime .
