Sommario/riassunto |

This brief describes a novel approach to overcome the disadvantages of hemp fibres in cementitious composites. The authors describe how the new approach includes the combination of thermal pre-treatment of nanoclay (producing calcined nanoclay) and chemical pre-treatment of fibre surfaces to improve the microstructure, mechanical, physical and thermal properties and also durability of hemp fibre reinforced cement composites. In this work, the synthesis of several materials are studied: nanoclay-cement nanocomposite, calcined nanoclay-cement nanocomposite, untreated & treated hemp fabric-reinforced cement composite, hemp fabric-reinforced nanoclay-cement nanocomposite |

and treated hemp fabric-reinforced nanoclay-cement nanocomposite. The influence of nanoclay on properties of cement paste and hemp fabric-reinforced cement composite is also presented together with the influence of NaOH pre-treatment of fibre surfaces on properties of hemp fabric-reinforced cement composite. The authors have aimed this brief at those working on environmental-friendly, biodegradable, building materials. |

Sommario/riassunto |
|
Why is it that even after two centuries of formal political independence and after the implementation of policies that were supposed to lead them to development, Latin American countries have not managed to overcome underdevelopment, poverty, and dependency? Why are the contradictions inherent to capitalism exacerbated in Latin America, in such a way that this region appears as the denial of the civilising promises inaugurated by capitalist modernity? Why do the asymmetrical relations in the world system and labour super-exploitation tend to deepen in the region, instead of being reduced? Why do the main social processes that challenge the capitalist relations of exploitation and domination take place in the ‘periphery’ of the system, not in its imperialist core? The essays collected in this book present the answers that Marxist dependency theory has formulated to these and other questions, by highlighting the processes and relations that characterise the heterogeneous deployment of capitalism as a world system and that define the particularities of Latin American dependent capitalism: the super-exploitation of labour-power, unequal exchange, the rupture in the cycle of capital, among others. It also highlights the relevance of the perspective inaugurated by Marxist dependency theory to explain the current problems of Latin America. |
