Thesis concrete pavement
Polyesters are an important class of commercial polymers, as are polyamides normally known as nylon Shakhashiri, Generally, as the polymer forms a low modulus phase with the polymer cement concrete, its creep is higher than that of plain concrete and decreases with the type of polymer latex used in the following order: polyacrylate, styrene-butadiene copolymer, polyvinylidene chloride, unmodified cement The major application of latex-containing polymer cement concrete is in floor surfacing, as it is non-dusting and relatively cheap and also because ofits lower shrinkage, good resistance to permeation by various liquids such as water and salt solutions, and good bonding properties to old concrete, it is particularly suitable for thin 25 mm floor toppings, concrete bridge deck overlays, anti-corrosive overlays, concrete repairs and patching Hing, Thus PET fiber is used for applications such as wearing apparel, curtain, upholstery, thread, tire cord filaments, industrial fibers and fabric for industrial filtration Venkatachalam et al.

Polymers can be natural orsynthetic. Its water absorption was less and it also had good resistance to acid. To determine the durability of cube specimens in acidic media 4. Thus, before the resin can be processed in a molding machine, it must be dried. Immediately after mixing, the cement particles and polymer particles are dispersed in the water. As of , 27percent — about kilometers of Myanmar roads were paved. Additionally, there are no existing standards on how to test the structural properties of pervious concrete in a laboratory setting.
Blocks should meet structural requirements for paving specified in terms of block compressive strength. Myanmar has a roads network ofkilometers.

It is this part which contributes the most to the elastic and final strength properties. Plastics block drains and gutters and causes floods. Ultimately, results of the research presented in this thesis are employed to develop a new guide for designing concrete pavements with zero maintenance of fatigue damage. MSc students are also quite often involved in smaller research projects which are initiated by industry and are tuned in such a way that they fit within the time available for an MSc thesis. Therefore there should be the need for proper waste management system. Contact The education and the research program of the Pavement Engineering Section concentrate on the characterization of pavement materials at various scales, using both experiments and numerical models, and the design and maintenance of various types of pavements. The aromatic ring coupled with short aliphatic chain makes thepolymer a stiff molecule as compared to other aliphatic polymers such as polyolefin or polyamide. And also, Myanmar is very potential to be a regional hub offering its geographical advantages to neighbouring countries to make maximum use of it for their beneficial transport linkages across the region. These MMDAs have contracted sanitation companies such as Zoom lion Ghana, Asadu Royal, and other agencies to clean the environment of the various waste generated from human activities.

Putrescible wastes tend to decompose rapidly and unless carefully controlled, decompose with the production of objectionable odors and visual unpleasantness. In many polymers, only one monomer is used.

Theuse of PET fiber can enhance the ductility of quasi-brittle concrete and, therefore, reduce the cracking caused by plastic shrinkage. Its water absorption was less and it also had good resistance to acid. The applications of concrete impregnated in depth in building and construction include structural floors, high performance structures, food processing buildings, sewer pipes, and storage tanks for seawater, desalination plants and distilled water plants, marine structures, wall panels, tunnel liners, prefabricated tunnel sections and swimming pools Hing, The polymer-cement ratio determines the amount of polymers present in the pore solution and present at the aggregate surface. There are three principal classes of composite materials containing polymers Hing, These blocks are rectangular in shape and have more or less the same size as the brick. In this study, Voltic bottles were first used to replace cement in the production of pavement blocks. According to the volume fraction of the polymer in the binder phase the material shifts from PCC, i. As of , 27percent — about kilometers of Myanmar roads were paved. Polymers are produced by chemical reactions in which a large number of molecules called monomers are joined sequentially, forming a chain. The second method employs the use PET fiber to reinforce concrete. Conventional Portland cement concrete has a number of limitations, such as low flexural strength, low failure strain, susceptibility to frost damage and low resistance to chemicals. Antwi of Civil Engineering Structures Lab. This is especially visible in the compressive strength of the mortar beams.
In this study, Voltic bottles were first used to replace cement in the production of pavement blocks. Recycled PET bottles used to produce mortar, have a promising results Zhang, Polymer wastes take years to degrade in the natural environment.

In the second studies when PET was used to replace quarry dust partially, the compressive strength was a little bit lower than the control. Fatigue test results were also used to study the long-term load-bearing capacity. A small, simple chemical unit appears to repeat itself a very large number of times in the structure of a polymer molecule or macromolecule. The current study found that the stress induced by curling is dominant, compared to that induced by external restraints. Moreover plastics arebeing littered andmisused all over the country and nowcausing threat to the nation. Awudza for his guidance, support and encouragement throughout the completion of this thesis. The EU funded EcoLanes Project Economical and sustainable pavement infrastructure for surface transport undertook extensive research and developed solutions for Steel-Fibre-Reinforced-Concrete SFRC pavements with a particular focus on using recycled steel fibres and roller compacted concrete. In this study, Voltic bottles were first used to replace cement in the production of pavement blocks. ABSTRACT The use of waste plastics in concrete pavement block is a partial solution to the environmental and ecological challenges associated with the use of plastics. Thus, before the resin can be processed in a molding machine, it must be dried. The preferred impregnated materials are acrylic monomer systems such as methyl methacrylate or its mixtures with acrylonitrile, because they have low viscosity, good wetting properties, high reactivity, relatively low cost and result in products with superior properties. To determine the engineering property compressive strength of samples of prepared polymer modified pavement blocks. These limitations are well recognized by the engineer and can usually be allowed for in most applications.
Therefore, there is the need for an economically recycling and value addition to the plastic waste generated in our communities.
Despite the efforts of these contracted sanitation companies, solid waste management problem is prevalent everywhere in Ghana.
The aromatic ring coupled with short aliphatic chain makes thepolymer a stiff molecule as compared to other aliphatic polymers such as polyolefin or polyamide.
Outlines of the Study This study consists of five chapters.
Polyethylene, polypropylene, polyethylene terephthalates and polystyrene which are non-degradable polymers form a major composition of the plastic wastes in the environment.
