Impacts of Using Crushed Rocks in Concrete (Civil Project ...
Concrete in Sweden has traditionally been manufactured with natural aggregate from glaciofluvial eskers. There is a need to preserve the remaining eskers because of their cultural value and importance for water filtration, thus natural aggregate has to be replaced. The most realistic alternative is to use crushed rocks.

IMPACTS OF USING CRUSHED ROCKS IN CONCRETE
Impacts of using crushed rocks in concrete v FOREWORD Aggregates from crushed rocks are in general flakier and have a rougher surface than natural aggregates. This leads to an increased cement demand. To avoid this aggregate producers have to learn how to identify rocks most suitable for concrete aggregate production and how to treat

Impacts of Using Crushed Rocks in Concrete.
The major problem with crushed rocks in concrete production is the workability. This is because crushed rocks have less favorable properties. The fragments are flakier and have a rougher surface than natural aggregates that have been rounded in water. Without any amelioration of the crushed rock, to reach a certain workability and strength, the ...
