CE-Marking of Natural Stone—Practical Application and Solutions in Sweden

Abstract: The European Construction Products Regulation (CPR) came into force the 1st of July 2013. Although much in the CPR and the harmonized product standards are clear and concise, some issues are still open for interpretation. In this paper, we give a brief background on the requirements associated with the CPR, from a natural stone perspective. Special conditions, like simplified test methods and responsibility for Factory Production Control, are presented. Finally, the pros and cons with the new CPR, as identified in continuous dialog with the Swedish natural stone industry, are ventilated.

Aggregate Quality Mapping of Sustainable Substitutes for River Sand for Concrete Production in Eastern Botswana

Abstract: Botswana is one of the most developed countries in Southern Africa. It has progressed steadily from being one of the world’s poorest countries in the early 70s to the middle income country it is today. In Botswana the classical, raw material for buildings, e.g. concrete and bricks, is the local river sand. Due to poor annual inflow of river sand and intensive construction in the area of the capital Gaborone, the few traditional resources that exist today are decreasing very rapidly. A major change from the use of river sand to crushed rock is identified as the most promising solution. The change is urgently needed to prevent a halt in development due to material deficit. A second alternative is to import most aggregates. However, such a solution is not considered advantageous for a sustainable and independent material supply. The results so far indicates that the good hard rock resources of Botswana manufactured with suitable crushing technique will remove one of the obstacles for the development of a modern society, e.g. the lack of river sand, and enable an infrastructural hub for trading.
