Abstract
Composite bulk Heat Insulation Made of loose Mineral and Organic Aggregate
Highlights
Creation of “green” building, using local resources and saving of energy are the most important tasks in modern construction sector, where the energy-efficient exploitation of the building is getting more important [1]–[4]
Porous aggregates and organic aggregates of local raw materials could be as appropriate materials in modern low-cost frame building systems. These mentioned aggregates and their mixtures are mostly local materials and in the future will promote the development of construction sector in Latvia
There are a lot of advantages using these aggregates, for example, inexpensive local materials, possibilities for use recycled materials, complicated space filling without gaps and improved sound insulation properties
Summary
Creation of “green” building, using local resources and saving of energy are the most important tasks in modern construction sector, where the energy-efficient exploitation of the building is getting more important [1]–[4]. At present in the Baltic states required value for wall thermal transmittance coefficient U should not be more than 0.18k W/mK, where k is factor of temperature [5] It depends on climatic conditions of the location, indoor design temperature according to use of building and the average outdoor air temperature during the heating season. Porous aggregates (made of recycled materials, for example foamed glass) and organic aggregates of local raw materials (waste of processing agriculture products, for example hemp and flaxen shives, peels of wheat) could be as appropriate materials in modern low-cost frame building systems These mentioned aggregates and their mixtures are mostly local materials and in the future will promote the development of construction sector in Latvia. The task of this study is obtaining of composite loose insulation which combines positive properties of mineral and organic component
