Is rammed earth more sustainable than concrete?

How is rammed earth a better alternative to concrete? Rammed earth is highly sustainable as it has a high thermal mass and a 40th of the carbon footprint of concrete which is composed of 20% cement. It is also completely recyclable and has low transport emissions as the main material is already on site.

Is rammed earth sustainable?

This is less than concrete but sufficiently strong for domestic buildings. Cured rammed earth has a high thermal mass. Environmental impacts are also kept low if the amount of processing of rammed earth materials is kept to a minimum (i.e. artificial additives) and material is sourced locally where possible.

What is the R value of rammed earth?

0.4/inch
Rammed earth has been used successfully in moderate to hot climates as the thermal mass effectively moderates the daily temperature swings, creating a comfortable living environment. Yet RE has a low thermal resistance and tests have determined its R-value to be only 0.4/inch (RSI = 0.07) [5].

How is the sustainability of a rammed earth?

The environmental sustainability is presented in S ection 3. The thermal performance of a rammed of the thermal mass of the material. Some conc luding remarks are finally offered in Section 5. 2. FINANCIAL AND SOCIAL SUSTAINABILITY OF RAMMED EARTH Easton 2007).

What are the building regulations for rammed earth?

Building Regulations. For walls constructed from stabilised rammed earth (SRE): Part A – Structure • Rammed earth has proved to be suitable for loadbearing and non-loadbearing construction. • Compressive strength is a maximum of 1MPa for unstabilised rammed earth and approximately 10MPa for stabilised rammed earth. Part B – Fire Safety

Where is rammed earth used in the world?

And while a range of these techniques have been used to build simple structures around the world, in the past few decades, one of them — rammed earth — has been modernized and used to create beautiful, sustainable buildings in Australia, Germany and Switzerland, and from the Southwestern U.S. up through California and the Pacific Northwest.

Can you use rammed earth in affordable housing?

But rammed earth is not only applied in affordable housing projects. Strangely enough, the other most common application is in expensive residential buildings designed by eccentric architects for wealthy and environmentally concerned clients. These houses usually end up in and and design magazines and are considered real pieces of art.
