Technical performance
- high flexural strength to accommodate construction movements
(hydraulic binders have low flexural strength)
- high-bond strength with compatible mortar/block mechanical
characteristics
- vapour permeability (the wall is breathing and moisture is not trapped
inside as with hydraulic binders)
- the right compressive strength (the "right strength" not the "super
rigidity of hydraulic binders")
Value performance
- at equal wall surface you will need up to 30% less Tradical® based
mortar than when using hydraulic binders
- this translates into less freight and in less product handling
- better workability (mortars can be reworked without affecting performance) and
better working comfort
Contribution to your health
- promotes good health
- kills germs
- no solvents inside
Contribution to the environment
- low energy mortar (compared to hydraulic binders)
- reabsorbs CO2 which is the setting agent (as opposed to water
for hydraulic binders) thereby reducing green house gas emissions
- high carbon capture (one m² of a 30cm thick Tradical® hemp-lime
wall can sequestrate up to 34 kgs of CO2)
- easily recyclable
Building requirements:
Controlled setting
- designed product setting characteristics that are suitable for each application
Excellent workability
- unused mixed materials can be re-worked within their pot life without downgrading their performance
Less waste
- unused materials do not harden quickly and become unusable waste
Higher productivity
- the ability to mix materials for a full shift's work decreases mixing time and increases productivity
Extended pot life
- designed pot life permits flexibility in working practices
High water retention
- product characteristic that ensures controlled setting performance
Design requirements over time
- low life-time maintenance
- high flexural strength accommodates movement
- compressive strength compatible with the mechanical properties of the construction blocks
- high bond strength minimises cracking
- high vapour permeability - walls can readily "breathe"
- reduction of condensation
- mould and germ resistant providing a healthier living environment
