Traditional construction systems with the bamboo species Guadua angustifolia Kunth (Guadua) are standardized under the Colombian code for seismic-resistant buildings. Thick cement renders contribute greatly to the wall mass and together with the foundations result on the highest negative environmental impact in traditional wall-framing construction with Guadua. Therefore, the reduction of the use of cement or its complete replacement for alternative binders in the wall-framing 'bahareque' system is a key point for environmental improvement.
This paper explores the potential use of lime as a replacement for cement mortars in 'bahareque' systems and analyses Guadua's anatomical and chemical features when mixed with lime. The paper describes a " cold process " in which no high temperatures are involved for the improvement of the bonding between lime and bamboo.
