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 (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.

Crushed rock sand – An economical and ecological ...

01-09-2016· Sahu et al. (2003) observed that concrete made using crushed rock sand attained the comparable compressive strength, tensile strength and modulus of rupture as the control concrete. Sahul Hameed and Sekar (2009) concluded that the compressive strength, split tensile strength and the durability properties of concrete made of quarry rock dust are nearly 14% more than the conventional concrete.
