The term 'grading' related to how the aggregates are used in the concrete mixture. A 'concrete grade' is a type of concrete. To learn more see our Concrete Grades Guide. The more closely packed the particles of the aggregate are, the greater its strength and therefore the greater the strength of the concrete. Poorly-graded concretes ...
In general, using waste material as lightweight aggregate decreases the concrete's overall weight. The materials used as lightweight aggregate in concrete are discussed in this study. According to research, utilizing trash as a lightweight aggregate not only improves the characteristics of concrete but also gives a sustainable approach to ...
In this paper, limestone quarries in the Bazian region, west of Sulaymaniyah city, northern Iraq, were evaluated geotechnically to examine their suitability for developing asphalt concrete for the ...
Therefore, the research problem is determined as the need to clarify the concept of concrete recycling and concrete waste recycling in Iraq, due to lack of local …
This study involved 86 experiments and 254 tests to determine the efficiency of reusing waste plastic in the production of concrete. Thirty kilograms of waste plastic of fabriform shapes was used as a partial replacement for sand by 0%, 10%, 15%, and 20% with 800 kg of concrete mixtures. All of the concrete mixtures were tested at room temperature.

aggregate's applicability was used for some structural uses of roads and concrete works in a few Kirkuk Governorate locations (northern Iraq) (Al-Tamimi, 2020).Morover, The Marshall method and the super pave method were tested with limestone aggregates in places other than Iraq. These methods worked
with Iraqi standard specification No. 5. 1984 was used. 2- Coarse and fine aggregate: gravel and sand from Salahia aggregate in Mosul was used gradation of coarse aggregate . 82-1973 as shown in Tables (1, 2) . TABLE I . GRADATION OF GRAVEL USED (COARSE AGGREGATE) Effect of Using Crushed Limestone in Concrete Mixes as …
Many concrete recycling strategies have emerged and many studies were devoted so as to find the best alternative to recycle concrete waste in order to produce recycled concrete aggregates (RCA ...
Answer: Fine aggregate is used in concrete to serve two purposes, 1. Provides a filler for the spaces between the coarse aggregates (like gravel or crushed stone) in a concrete mix. 2. This helps to reduce the void content in the concrete mixture, enhancing the overall compactness and workability of the material.
Natural aggregate is the main source of aggregate used in concrete work in Iraq. Synthetic aggregate is also used in limited scale around the world. An industrial solid waste is produced from iron and steel industry. It was physically treated and fully inspected and incorporated in concrete as coarse aggregate. The concrete mixes …
This study insures that reusing waste plastic as a sand-substitution aggregate in concrete gives a good approach to reduce the cost of materials and solve some of the solid waste problems posed by plastics. ... The fine aggregate was natural sand of 4.75 mm maximum size obtained from the Al-Ukaider area in Iraq. The …

The coarse aggregate used in this study was naturally available in the eastern region of Iraq, from a place known as Chlaat (Maysan, Iraq) and used in the concrete material. The maximum size of the coarse aggregate used this study was 10 mm. Grading of the coarse aggregate was computed based on the IQs No.45 Zone II (1984) as shown in Table 4.
Coarse aggregates have properties such as size, shape, moisture contents, specific gravity, density etc. which affects concrete strength and durability in many ways. These effect of aggregate properties on concrete are discussed in detail. Concrete is a mixture of cementitious material, ...
