Concrete is the widely used material in the world. This automatically creates a huge demand for ingredient of concrete (Fine Aggregate, Coarse Aggregate and cement). From the environment point of view, the huge extraction of the aggregate creates depletion and manufacturing of cement .
· Concrete of 300 and 400 dosages was produced by adding various amount of sunflower seed husk (5, 10, 20 and 30 percent). They produced concrete samples with a density of around 2,000 tones per cubic meter – the lowest density could be classified as "lightweight". Introduction of sunflower seed husk dramatically reduced the unit weight ...
The asphalt and aggregate are usually mixed and heated at a central loion. Asphalt concrete surfaces are fairly easy to construct and repair [1]. Materials and Methods . Sourcing of materials . The palm kernel shells were obtained from the local market and crushed to remove the seeds.

uncrushed olive seed content with watercement ratio of had a 28day compressive strength of N/mm2. Ibrahim (2 001) studied the use of crushed olive seed shell as full replacement for coarse aggregate in concrete and observed that at full replacement there was a 9% increase in the 28day compressive strength of the concrete with ...

· Sunflower seeds are pretty yummy, but they come with a lot of waste. Unless you buy a bag of them that are just the seeds, you often have a huge pile of broken and decrepit shells to go along with them. As it would turn out, if you collect enough of those husks, you'll have a suitable source of aggregate, or filler for concrete.
· The aspect of sunflower used in the present study â€" from stalk to treated aggregates: (a) sunflower stalks, (b) shredded sunflower stalks, (c) sunflower aggregates treated with solution of sodium silie, (d) dried sunflower aggregates after their treatment The water/cement ratio for reference concrete was set at, but using a superplasticizer additive it was reduced at
· The Effects of Sunflower Seed Husk (SSH) as aggregate replacement materials on concrete properties were investigated using different amounts of physical and mechanical properties. Concrete of 300 and 400 dosages was produced by adding various amount of SSH (5, 10, 20 and 30%).
· 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 .
Days to anthesis of 'Pacino Gold' sunflower were not influenced by aggregate type and percentage; therefore, data were pooled and analyzed by paclobutrazol rate. The mean number of days to anthesis was 78 d for the untreated control and was 80, 80, and 79 d for the 1, 2, and 4 mg/pot paclobutrazol concentrations, respectively.
Aggregate is a granular material, such as sand, gravel, crushed stone used with a cement to produce either concrete or mortar. Aggregate is relatively inexpensive and does not enter into complex chemical reactions with water; it has been customary, therefore, to treat it as inert filler in concrete and mortar.
· Seeds for averagesized flower should be spaced at least 2 feet apart and in rows of 3 feet away from each other. For large sunflowers, space seeds at least 3 feet apart in rows 3 to 4 feet wide. Step 5 Use a Fence or Post. Since sunflowers can grow so .
to make highstrength concrete, it is easier to do so with coarse aggregates below mm (Y, in.) (ACI 36395). There has not been much research on the effects of coarse aggregate content
Cement is a fine powder that is the principal strengthgiving and propertycontrolling component of concrete. A mixture of cement, aggregates and water hardens to form concrete which is used for everything from sidewalks, homes, roads, bridges, dams and skyscrapers. Cement is used in virtually all forms of construction.
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 appliion 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.
Black oil sunflowers produce seeds used for sunflower oil, seed and other animal feeds. If you leave the seeds on the flower heads to dry, you will have an abundance of birds feeding on oil sunflower seeds can also be dried and used as healthy snacks full of vitamins E and B6.
· Exposed Aggregate is pre mixed before it is transported to site where Seeded Aggregate is hand seeded at the time of concrete placement which gives a more tailored effect than the Exposed Aggregate option. For something different, choose the illuminating option.

They developed a concrete with sunflower aggregates and a pumicelime binder, w ith . binder/aggregate mass ratio estab lished to 18. Compressive st rength at 28 day s of this type of concrete .
The sunflower seeds used in the laboratory experiments during the storage period (15,30,45,60,75,90,105,120,135,150 days) were taken by using the drilling system from the middle of warehouse which is belonging to the Black Sea Cooperatives Union of Oilseeds (Fig. 1). Firstly, sunflower seeds brought to laboratory
