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.

Studying the Probability of Using Groundwater in Baghdad City for Human, Animal, and Irrigation Use
...Show More Authors

Groundwater is an important source of fresh water especially in countries having a decrease in or no surface water; therefore itis essential to assess the quality of groundwater and find the possibility of its use in different purposes (domestic; agricultural; animal; and other purposes). In this paper samples from 66 wells lying in different places in Baghdad city were used to determine 13 water parameters, to find the quality of groundwater and evaluate the possibility of using it for human, animal and irrigation by calculating WQI, SAR, RSC and Na% and TDS indicators. WQI results showed that the groundwater in all wells are not qualified for human use, while SAR and RSC indicated that most samples are suitable for irrigation use, and

Effect of Construction Joints on Performance of Reinforced Concrete Beams
...Show More Authors

Construction joints are stopping places in the process of placing concrete, and they are required because in many structures it is impractical to place concrete in one continuous operation. The amount of concrete that can be placed at one time is governed by the batching and mixing capacity and by the strength of the formwork. A good construction joint should provide adequate flexural and shear continuity through the interface.

In this study, the effect of location of construction joints on the performance of reinforced concrete structural elements is experimentally investigated.

Nineteen beam specimens with dimensions of 200×200×950 mm were tested. The variables investigated are the location of the construction joints

Flexural Behavior of Partially Pretensioned Continuous Concrete Beams
...Show More Authors

This paper describes flexural behavior of two spans continuous rectangular concrete beams reinforced with mild steel and partially prestressing strands, to evaluate using different prestressing level and prestressing area in continuous prestressed beams at serviceability and ultimate stages. Six continuous concrete beams with 4550 mm length reinforced with mild steel reinforcement and partially prestressed with two prestressing levels of (0.7fpy  or 0.55fpy.) of and different amount of 12.7 mm diameter seven wire steel strand were used. Test results showed that the partially prestressed reinforced beams with higher prestressing level exhibited the narrowest crack width, smallest deflection and strain in both steel and concrete at ul

Direct Shear Behavior of Fiber Reinforced Concrete Elements
...Show More Authors

Improving the accuracy of load-deformation behavior, failure mode, and ultimate load capacity for reinforced concrete members subjected to in-plane loadings such as corbels, wall to foundation connections and panels need shear strength behavior to be included. Shear design in reinforced concrete structures depends on crack width, crack slippage and roughness of the surface of cracks.

This paper illustrates results of an experimental investigation conducted to investigate the direct shear strength of fiber normal strength concrete (NSC) and reactive powder concrete (RPC). The tests were performed along a pre-selected shear plane in concrete members named push-off specimens. The effectiveness of concrete compressiv

The reality of Taxation in Iraq and Aspect of it’s Development
...Show More Authors

This research is considered a simple attempt and effort which is it first and last target is to point at the procedures of the taxes account that aims to reduce the taxes from the persons and give free to the person who estimates the tax to practice what comes from the competent authorities to describe the person who estimates the tax and not an accountant who practice the accountant procedures which are imposed on him by the annual terms from higher administrations , So he can not evaluate   state of the person who pay the tax , and he might be dissatisfied with his job , because his role can’t  be activated from the general foundation taxes.

And so , this research includes four fields:-

The Use Of Genetic Algorithm In Estimating The Parameter Of Finite Mixture Of Linear Regression
...Show More Authors

The estimation of the parameters of linear regression is based on the usual Least Square method, as this method is based on the estimation of several basic assumptions. Therefore, the accuracy of estimating the parameters of the model depends on the validity of these hypotheses. The most successful technique was the robust estimation method which is minimizing maximum likelihood estimator (MM-estimator) that proved its efficiency in this purpose. However, the use of the model becomes unrealistic and one of these assumptions is the uniformity of the variance and the normal distribution of the error. These assumptions are not achievable in the case of studying a specific problem that may include complex data of more than one model. To

Role of Carbon Dioxide on the Corrosion of Carbon Steel Reinforcing Bar in Simulating Concrete Electrolyte
...Show More Authors

The main factors that make it possible to get the corrosion of reinforcing steel in concrete are chloride ions and the absorption of carbon dioxide from the environment, and each of them works with a mechanism which destroys the stable immunity of rebar in the concrete. In this work the effect of carbon dioxide content in the artificial concrete solution on the corrosion behavior of carbon steel reinforcing bar (CSRB) was studied, potentiostatically using CO2 stream gas at 6 level of concentrations;  0.03 to 2.0  weight percent, and the effect of rising electrolyte temperature was also followed  in the range 20 to 50 C. Tafel plots and cyclic polarization procedures were obeyed to investigate the c
