Importance of New Use of Concrete in Iraq Analysis of Development And Use of Concrete in Architecture
...Show More Authors

Since its invention by the Ancient Romans and later developed during the mid-18th century, the concrete structure and finish, has been considered as the most powerful, practical, economic and constructional material that meets the building’s architectural and aesthetical requirements. By creating unique architectural forms, the pioneer architects used concrete widely to shape up their innovative designs and buildings.

The pre-mixed ultra-high performance concrete which manufactured by Lafarge.

The transparent concrete and cement that allow the light beams to pass through them, introduces remarkable well-lit architectural spaces within the same structural criteria. This product is a recyclable, sustainable, friendly environmental and cost efficient back up.

Due to its characteristics, strength, flexibility, affordability and long term performance, the concert integrated and contributed in modern architecture, urbanism and civil developments. Apparently, most of the 20th Century architects employed high-tech concrete method to deliver Iconic and bespoke architectural monuments world-wide. The interaction between the architectural form and the concrete as a buildable, executable, structural and constructional material has been always the main concern for architects over generations.

The formalism in architecture was first identified by the Art-Nouveau movement during the early 20 century in Europe as well as in Northern America. It formed, utilized and sculptured the concert to meet the use, function, aesthetical and spatial needs of spaces. This wave generated series of most significant, outstanding and impressive buildings in the architectural symbolized record.

This was followed by the Brutalism architecture presented by Alison and Peter Smithson in England and also by Le Corbusier works in Marseille and India. However, Alvar Alto and Louis Khan have participated and established a tremendous use of concrete to erect public interest developments on the same era

The concert as a structural element dominated the Metabolism architecture that represented by the Japanese architects like Kiyonori Kikutake, Kisho Kurokawa, Noboru Kawazoe, Masato Otakaand and Fumihiko Maki. They visualized the city of the future to be viable, evaluable, expandable, flexible structures that evoked the processes of organic growth as it is in nature. Their developments are often called technocratic and described as avant-garde with a rhetorical character. The Metabolist mega structures heavily relied on advanced technology and adaptable plug-in building techniques in using this material.

The research concluded the influences of the concrete as a building material upon the modern and building forms from the outsets. By exploring the history of the material, expanding its characteristics and specifications and later demonstrating the modern architecture movements and architects, this research has achieved its targets to acknowledge the importance of concrete in the current construction market and architectural developments.

The aim of the current research is to study the effect of adding green tea to the edible film prepared from the whey protein isolate on the effectiveness of microorganisms and evaluating the of antimicrobial effectiveness of these films on Iraqi soft cheese packaging during the nine days of storage as an alternative to commercial packaging. At the beginning of the study, the minimum inhibitory concentration was measured by calculate the diameter of the zone of inhibition on growth of the bacteria and it's included the group of Gram negative bacteria (Escherichia coli, Salmonella spp, Pseudomonas Aeruginosa) and the group of Gram positive bacteria (Staphylococcus Aureus, Bacillus spp) and a yeast (Candida Albican). Where the diameter of t

Using Polyurethane Coating of Concrete Pipes with Acid Attack Resistance in Sewer Lines
...Show More Authors

One of the most important challenges facing the designers of the sewerage system is the corrosion of sewers due to the influence of sewerage contaminates which lead to failure of the main lines of sewers. In this study, a reference mix of 1: 1.5: 3 was used and the 4% Flocrete PC200 by weight of cement was added to the same mixing ratio in the second mixture. Twenty-four samples were tested for each mixture, 12 of which were used to compression strength test in ages (7, 14 and 28) day and six samples were submerged after 28 days of wet treatment at (5 and 10) % concentrations of sulfuric acid. The other six samples were painted after 28 days of wet treatment with coating Polyurethane and after 24 hours were flooded with a concentrat

Reuse of Glass waste as a partial replacement to fine aggregates in concrete
...Show More Authors

As human societies grow, the problem of waste management becomes one of the pressing issues that need to be addressed. Recycling and reuse of waste are effective waste management measures that prevent pollution and conserve natural resources. In this study, the possibility of using glass waste as an alternative was used as a partial weight substitute for fine aggregates with replacement ratios of 10, 20, 30, and 40% by the weight, and formed into test models (15 cm * 15 cm ) cube and (15 cm * 30 cm) cylinder, then matured and tested their strength compression and tensile strength at the age of 7 and 28 days and compared with a reference or conventional concrete with a mixing ratio (1: 1.5: 3) as well as testing its worka

Enhancement of self-healing to mechanical properties of concrete
...Show More Authors
Abstract<p>Concrete is the main construction material of many structures. Exposing to loads creates cracks in concrete, which reduce the performance and durability. The decrease of concrete cracks becomes a necessity demand to ensure more durability and structural integrity of the concrete structure. Autogenous healing concrete is a kind of new smart concretes, which has the ability to reclose its cracks by means of itself. Concrete self-healing is a type of free repairs processes, which is reduce direct and indirect cost of maintenance and repairing. This work targets to inspect the mechanical properties of concrete after using two combinations of two materials (20 kg/m3 calcium hydroxide Ca(OH</p> ... Show More

Abstract<p>The research’s main goal is to investigate the effects of using magnetic water in concrete mixes with regard to various mechanical properties such as compressive, flexural, and splitting tensile strength. The concrete mix investigated was designed to attain a specified cylinder compressive strength (30 MPa), with mix proportions of 1:1.8:2.68 cement to sand to crushed aggregate. The cement content was about 380 kg/m<sup>3</sup>, with a w/c ratio equal to 0.54, sand content of about 685 kg/m3, and gravel content of about 1,020 kg/m3. Magnetic water was prepared via passing ordinary water throughout a magnetic field with a magnetic intensity of 9,000 Gauss. The strength test</p> ... Show More

Effect of Hydrated Lime on the Properties of Roller Compacted Concrete
...Show More Authors

Roller compacted concrete (RCC) is a concrete of no slump, no reinforcement, no finishing, and compacted using vibratory roller. When compared with conventional concrete, it contains less water content
when compared to traditional concrete. The RCC technique achieves significant time and cost savings during the construction of concrete. This study demonstrates the preparation of RCC slab of (38 ×38× 10) cm
samples by using roller compactor which is manufactured in local markets. The Hydrated lime additive is used to study the mechanical and physical properties of that RCC slab samples. This investigation is divided
into two main stages: The First stage consists of hammer compaction method with two gradation of aggregate, dense
