Earth Bricks with Halloysite Nanoclay: Research and Experimentation for the Sustainability of Materials

2021

This paper illustrates the experimentation activities on rammed earth and nanotechnologies. The experimental research was carried out with the aim of improving the performance of rammed earth bricks with clay nanotubes, creating a ‘new material’ with reduced embodied energy and low CO2 emissions into the atmosphere. Specifically, the analysed performances are related to the compressive strength that expand their area of use as a building material.

Numerical seismic performance of a rammed earth dwelling considering the use of a textile reinforced mortar system

Rammed earth buildings represent a considerable portion of the existing vernacular building stock of several countries and they are very common in the southern region of Portugal. The historical and architectural values of these constructions, along with their recognized high seismic vulnerability, have made the structural rehabilitation of earthen buildings a priority among the scientific community. Despite some recent studies, the prediction of the seismic response of these buildings is still a challenging task. This paper presents the results of a numerical investigation on the seismic behaviour of a representative rammed earth building located in Alentejo (South of Portugal). Numerical …

SUSTAINABLE ARCHITECTURE: THE ECO-EFFICIENCY EARTH CONSTRUCTION

2017

The appropriate choice of building materials can contribute decisively to reduce the energy consumption of the building sector. The increasing worries for the environmental impact of construction materials is witnessed by a lot of studies The mentioned worries has brought again the attention towards natural materials. The use of more sustainable construction materials and construction techniques represent a major contribution to the eco-efficiency of the construction industry and thus to a more sustainable development. Within this frame the renewed interest for a natural material such as the rammed earth is included; the interest has been in continuous growth from the 80s till today. The ra…

INNOVAZIONE DEI MATERIALI NATURALI: TERRA E NANOTUBI DI ARGILLA PER UNA SFIDA SOSTENIBILE

2019

All’interno del dibattito culturale che vede la questione ambientale come prioritaria e con riferimento a studi e ricerche che negli ultimi anni hanno promosso materiali compositi a base di terra cruda, gli Autori, consapevoli della necessità che il rapporto fra Progetto e Materia debba assumere una nuova centralità supportato dalle specificità della Tecnologia dell’Architettura, illustrano le risultanze di una sperimentazione che ha l’obiettivo di migliorare le prestazioni della terra cruda con l’apporto delle nanotecnologie, sviluppando un ‘nuovo materiale’ con una ridotta embodied energy e una ridotta quantità di emissioni di CO2 in atmosfera.

Within the cultural debate that considers the environmental issue as a priority and with reference to the studies and researches that over the last years have supported compound materials containing rammed earth the Authors aware of the need of giving to the relationship of Project and Matter a key role supported by the characteristics of Architectural Technology show the results of an experimentation that aims to improve the performance of rammed earth with the contribution of nanotechnologies developing a ‘new material’ with a reduced embodied energy and a reduced amount of CO2 emissions into the atmosphere.Settore ICAR/12 - Tecnologia Dell'Architettura
