To reconstruct Iraqi infrastructure, high performance building materials are needed for structural applications. This project will provide proven methodologies for manufacturing superior performance concrete with high mechanical strength, improved durability, water tight and high corrosion resistance, based on using polymers and locally available raw materials as cement additives

The high performance concrete composites will be suitable for the major construction projects in Iraq, solving the problems related with using conventional concrete such as delayed hardening, low tensile strength, susceptibility to cracking, and inferior chemical resistance

Improvement the disadvantages in conventional concrete. Establishment of proven methods to manufacture high performance concrete systems which are well defined related to (mix design, mixing procedure and curing conditions) For different specified application e.g. :

Sewage pipes, drainage channels, highway and bridge decks, concrete columns used in harsh environments (very saline areas) for holding electricity wires, pre-cast wall reinforced panels, quick repairs of concrete overlays, dams, pipes and utility components.

Materials (cement and aggregates) , pozzolanic materials: limestone powder , silica fume fly ash , slag and burnt clays , crushed brick , natural fibers: reed , date palm frond , stalk and leaf , natural fillers: cane bagasse , wood ash , saw dust , paper waste , etc . Laboratory space. Some testing machines and equipments.

Materials: (Various types of polymers latexes and additives) : Epoxy , unsaturated polyester , phenolic resins , styrenebutadiene , polyurethane, methylmethacrylate and furan , Superplasticizers and other concrete admixtures. Some testing equipments.

Concrete is a construction material that is widely used in Iraq. It is composed mainly of three materials namely; cement, water and aggregates as well as an additional material known as admixture. The mixture is then allowed to cure by chemical means. It continues curing for a long time and consequently the concrete grows stronger with age.

Concrete used in Iraq has some disadvantages such as delayed hardening, low tensile strength, susceptibility to cracking and inferior chemical resistance. To lessen disadvantages and upgrade its performance a polymer – concrete is suggested for the construction purposes.

Proven methods have been active in many countries such as Japan, USA, Germany and the U.K. However, Iraq lacks such experience and due to existence of its basic raw materials a proposal is suggested to construct a proven methodology for its manufacture in Iraq in accordance with the available resources, raw materials that are abundantly available in Iraq and based on the economical background.

The project is evaluating new concrete making materials that are resistant to deterioration. The goal is to determine those concrete processing techniques and materials that have the best potential for superior performance with a wide range of aggregates types and to develop criteria and recommendations for their development and application.

The Modified Polymer Concrete Composite (MPCC) project concentrates on the following main areas:

Provide a technical guide on the production and use of the three types of modified polymer concrete composites; polymer impregnated concrete (PIC), Polymer cement concrete (PCC) and polymer concrete (PC).

Explore the feasibility of developing appropriate mixture proportions for the three different categories of modified polymer concrete composites with only locally available conventional constituents materials and normal production and curing procedures.

It covers the short-term mechanical properties; creep, shrinkage, and temperature effects; bond and fatigue characteristics, durability and its implication for the performance of concrete mechanics.

The use of chemical admixtures can be particularly helpful in achieving the desired properties of the concrete, but appropriate test methods and specifications for test methods need to be developed. The range of available quality testing approaches is to be reviewed.

To study the microstructure of concrete before and after improvements in order to generate knowledge which will enable improvement in the quality of MPCC by controlling the development of the microstructure.

A study is to be carried out to determine the properties of MPCC produced with several sets of materials. Properties can vary significantly depending on the specific raw materials used and the strength level attained.

Development of a method for the design and optimization of polymer concrete composites using a fundamental approach based on material models of polymer concrete

Raw Materials to be used as fillers or aggregates: Pozzolanas (materials containing silica in a reactive form) Rice hask Ash Silica fume Fly Ash ( Knon also as pulverized – fuel ash ) Slag (filler or aggregates) Limestone powder (filler) Limestone (Aggregate) Natural fiber (Reed, Datepalm frond, Datepalm stalks, Datepalm leaf)

1. Project A1 “Microstructure Development” The foundation of this research program is investigation of the chemistry and physics of cement and concrete systems at the microstructure level under project A1. Control of the physical and chemical processes that take place during mixing, placing and curing stages is a fundamental step towards advancement of concrete technology.

2. Project A2 “Optimization of Concrete Technology” This project will build on the knowledge gained in A1 project and extend it to development of new concrete methodologies for increasing the durability and service life of structures. This project will critically evaluate new materials and processes in concrete technology and establish plans for using them in various applications. Specifications of environment specific superior concrete will be produced.

3. Project A3 “Mechanical Behavior Of High Performance ”Concrete and MPCC Is utilizing quantitative relationships between the mechanical properties and behavior of MPCC in service under varied environmental conditions (moisture, humidity, temperature, exposure to marine environments and deicing agents, etc). These relationships will be used a basis for development of .engineering guidelines for use of the material

4. Project A4 “Non-destructive Testing for Quality .Control / Condition Analysis of Concrete Is using improved quality control / quality assurance system for assessment of new concrete used in various applications. These systems will be based on rapid, reliable, and non-destructive field tests that can be applied at critical points during the construction process

1. A manual for user – friendly material model program used for the design and optimization of polymer concrete composites. 2. The research has been planned to result in tangible products that can be applied in the field immediately.

3. An expert system based on the knowledge and data obtained from the MPCC project and information obtained from the literature. The expert system would allow engineers to diagnose concrete problems, select appropriate materials and mix designs for both new constructions and rehabilitation and ensure optimum performance in the design environment.
