Industrial activities in Iraq are associated with significant amounts of non-biodegradable solid waste, waste plastic being among the most prominent. 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 ...

2019-7-27 The reuse of materials from destroyed structures as recycled aggregate for concrete has become an important issue, especially in Iraq’s Mosul City following the war of 2017. Many water types which are unacceptable for drinking, such as the well water available in Mosul, may be used in concrete, avoiding the need to use precious potable water.

2017-8-5 Hydraulic cement concrete is a cement and water paste in which aggregate particles are embedded. Aggregate is granular material such as sand, gravel, crushed stone, blast-furnace slag, and lightweight aggregates that usually occupies approxi-mately 60 to 75% of the volume of concrete. Aggregate properties significantly affect the workability of plastic

2014-5-13 Using multilinear correlation analysis, the influences of these aggregate characteristics and other parameters on the properties of recycled aggregate concrete were evaluated. The results showed that the performance of the concrete containing each type of RA was largely influenced by the aggregate nature and quality, in addition to attached ...

2016-12-14 Ghazi [10] investigated the use of crushed clay brick aggregate concrete. Mechanical properties such as compressive strength and splitting tensile strength as well as physical tests such as UPV test were done. The test results of crushed clay aggregate concrete are compared with natural aggregate concrete and the results of compressive strength ...

2010-4-14 Wet cure the concrete and use hot weather placement procedures (assuming it will placed in the summer in a hot climate). Consider using dowels for load transfer at the joints. This will make the slab more serviceable and require less maintenance. You can use round dowels, plate dowel baskets, or other proprietary systems.

2020-7-23 40mm aggregate is used for PCC in foundation or base course in rigid pavement. Generally the 9.5-37.5 mm diameter range aggregate are used in RCC concrete work. But Maximum size of aggregate generally on site used are 4 0 mm. For ease of compaction and workability sometimes on site 10-15 mm aggregate are used.

2019-7-30 ITZ between the aggregate particle and the cement paste [23]. Studies [18, 24, 25] have shown that the addition of nanosilica results in increased compressive, tensile, and exural strength of conventional concrete. Studies on the use of nanosilica to upgrade the perfor-mance of RAC are very limited [26]. Hosseini et al. [27, 28]
