Limecrete is a combination of natural hydraulic lime and lightweight aggregate or sand which can be used as an alternative to concrete. This creates a breathable floor slab with a certain amount of flex.

This depends on various factors such as the lime type and content, whether it contains fibres and the ambient temperature. It is possible to move over the floor using boards after a few days. The slab will continue to strengthen over the following months. It is possible to lay a floor finish such a stone bedded in a lime based product after 21-28 days but you will need to wait much longer to install a floor such as engineered wood as the moisture content will need to be much lower (2-3%)for this type of floor to prevent it from warping.

Limecrete is strong enough under compression to be used as the floor slab in a home. It can be strengthened by increasing the lime content and by adding fibres. This makes it suitable for applications such as a workshop floor. The lime content should not be increased excessively as this compromises breathability.

A volumetric mixer measures the correct ratios of lime, aggregate and water. These are then forced through an auger to combine them. When you try to mix limecrete in a conventional drum mixer the different ingredients tend to ball together. It is tempting to splash more water in to loosen the mix the way you can with cement, but this substantially weakens the limecrete.
