Lightweight Aggregate and Lightweight Concrete and its Application in the Improvement of the Thermal Properties of Volcanic Lightweight Aggregate Concrete Blocks From Canary Islands Available to Purchase

Concrete blocks with volcanic aggregates currently produced in the Canary Islands (BHIC) have a high coefficient of thermal conductivity. The application of Spanish Building and Construction Regulations, known as CTE, leads to the need for multilayer construction systems in external building walls. These systems are less efficient from an economic and environmental point of view. This Paper focus on the improvement of thermal properties of the BHIC, so that the external building walls can be executed in the islands using single-leaf masonry without having to add thermal insulation.
