Sunflower seeds to promote ecofriendly concrete
Sunflower seed husks, a huge waste product of the vegetable oil and food industry, could be used as an environmentally friendly filler, or aggregate, for concrete according to Turkish researchers. The team of Namik Kemal University in Turkey demonstrated that the use of husks reduces the density of concrete as well as boosting the material''s resistance to cracking after exposure to icy conditions.

Concrete Road Crushing Recycling Fine Aggregate Sand Mining Europe. In developing regions of the world, especially in the asiapacific and africamideast regions, the report predicts that demand for sand will be supported in the near term by high incidences of illegal mining, as fine aggregates will still be required in a number of applications, particularly for hydraulic concrete.

· Rounded aggregate usually takes less time to seed than crushed aggregate. Concrete for the base slab should meet requirements outlined by the ASTM C 94 Specifications for Ready Mixed Concrete. Use a threequarterinchmaximumsize coarse aggregate in the base concrete to simplify embedment of the seeding aggregate.

Based on the test results and comparison a conclusion was made that the concrete reinforced with ash of shells of sunflower seeds was less suitable for concrete application compared to concrete with stone flour. The reason for this is the low prosessingability of such a concrete mix which is the cause of poorer compaction in the molds.

· Organic aggregates are less stable than inorganic aggregates and are therefore more difficult to use in a concrete mix with both inorganic and organic binders. Among other reasons, this is due to the disproportionate amount of water required in the mixing of plantbased concretes and to the release of organic compounds, which can have serious effects on the hardening process.

Aggregate Concrete an overview ScienceDirect Topics. The reasons for the limitation of steel slag as an aggregate in concrete arise mainly from two issues: (i) the variation of volume stability of steel slag per se (some concretes containing steel slag aggregate might disrupt due to volume expansion of steel slag particles) and (ii) the lack of experimental and theoretical work and the fact
