We only use good quality Natural Hydraulic Lime (NHL), which we know not to contain any sort of potentially damaging components. One of the most exciting elements of the Circle Organic farm project is the home-made hydraulic lime plaster we successfully used on the interior and exterior walls of the building. It produces good mortar. Hydraulic limes set by hydrolysis, a reaction caused by water. Moderately hydraulic lime. It is supplied in powdered form, it is pretty much the same as mixing and working with a modern cement. Traditional mortar with the practical benefits of a modern mortar. Consist primarily of 2CaOsb.2, Ca(OH)2, CaO and 2CaOsb.2O3. Hydraulic lime is a useful building material for the following reasons: Hydraulic lime concretes have been in use since Roman times, either as mass foundation concretes or as lightweight concretes using tufa or pumice as aggregates and a wide range of pozzolans to achieve different strengths and speeds of set. Eminently hydraulic lime contains 21-30% clay, slakes very slowly, and sets in approximately a day. Mosswood Gold It can be used where strength is required brick masonry, stone masonry, and under water constructions. Base Coat [1], Artificial hydraulic lime (AHL) or artificial lime (AL) becomes hydraulic when hydraulic and/or pozzolan materials are added either before or after burning in a lime kiln. The complete range, solutions for any lime plastering project. Oatmeal, medium coarse, archetypal lime mortar. It is suitable for good class of mortar, brick work and masonry. Stone and masonry sealer with satin finish. It is used for better quality work and exterior walls in freezing climates. Hydraulic lime mortars are indistinguishable from non-hydraulic limes. Traditional mortars derived from Scottish limestones were often slightly hydraulic. Lime putty is fabulicious, and you can use it in plaster, as a lime wash, or in lime mortars.

Quicklime can be combined with a natural hydraulic lime (NHL) to produce a gauged mortar. It is a type of cement, similar to mortar, that sets extremely fast and hardens after it has been mixed with water. Hydraulic lime provides a faster initial set and higher compressive strength than air lime and eminently hydraulic lime will set in more extreme conditions including under water. This means it is extremely flexible and allows for movement and thermal expansion. Secil NHL 2 - Natural Hydraulic Lime Gauged mixes. There are two basic types of hydraulic limes: Natural hydraulic lime (NHL) is produced by heating (calcining) limestone that naturally contains clay and other impurities: no materials may be added to create the hydraulicity. It is used for better 3. Consists mainly of hydrated lime with one or more pozzolans with possible inclusion of inert filler.

Hydraulic lime is a type of lime, or calciumcarbonate, which is used to make mortarand plaster products. Lafarge has a long and strong track record of producing Natural Hydraulic Lime stretching back to the mid 1800s. The lime is able to reduce plasticity and moisture-holding capacity. It is softer and sets much more slowly than hydraulic lime and remains softer for longer as the carbonation process is very slow. It is less dense than cement, thus less cold bridging. When Portland cement, even traces, is present (can be up to 20% of binder weight), it has to be labeled as 'PHLc'."[1]. Fox Cragg Eminently hydraulic lime (NHL 5) is used for external work in exposed areas, such as chimneys and for floor slabs/underpinning. The TXI Hydrated Lime 50 lb.
