Pumice Stone specifications

The consistent quality of LAVA pumice stone stems from the deposit homogeneity and systematic controls integrated into all production process stages. The high quality of pumice stone products is guaranteed by their CE marking based on the European standards and the certification tests according to ASTM standards: 
1. ΕΝ 13055-1: 2002   Lightweight aggregates for concrete, mortar and spout

2. ΕΝ 13055-2: 2004   Lightweight aggregates for bitaminous mixtures
                                          and surface treatments and for unbound and
                                          bound application

The House ABCD+

The ABCD+ House, designed by French builder Cecile Robin and using Lafarge materials, was inaugurated in 2012 in Roanne (France).

This positive-energy detached concrete house, the result of a close partnership with building firm Cecile Robin Construction, is inspired by the PRO-eco initiative set up by Lafarge in France to make sustainable construction simpler for building professionals.

Combining traditional techniques and innovative materials such as pumice-stone concrete block, the house meets the requirements of 2020 Thermal Regulation as of today. It also offers an urban, architectural and environmental answer to the new challenges of the sustainable city. The house was awarded the golden medal in the "Urban Challenge" category for the House of the Year 2012 classification by French Houses Union.
