Polymer Cement Composite
Polymer Cement CompositePolymer - a substance that has a molecular structure consisting chiefly or entirely of a large number of similar units bonded together, e.g., many synthetic organic materials used as plastics and resins.Polymer Concrete- type of concrete that use polymers to replace lime-type cements as a binder. In some cases the polymer is used in addition to Portland cement to form Polymer Cement Concrete (PCC) or Polymer Modifed Concrete (PMC)
Manufacturing of Polymer Cement CompositeIn polymer concrete, thermoplastic polymers are used.More typically thermosetting resins are used as the principal polymer component due to their high thermal stability and resistance to a wide variety of chemicals.Composed of aggregates that include silica, quartz, granite, limestone, and other high quality material.The aggregate must be of good quality, free of dust and other debris, and dry. Failure to fulfll these criteria can reduce the bond strength between the polymer binder and the aggregate.
Manufacturing of Polymer Cement Composite
Applications of Polymer Cement CompositePolymer concrete may be used for new construction or repairing of old concrete.Repair of both polymer and conventional cement-based concretes.Used in swimming pools, sewer structure applications, drainage channels, electrolytic cells for base metal recovery, and other structures that contain liquids or corrosive chemicals.Suited to the construction and rehabilitation of manholesIt can also be used as a bonded wearing course for asphalt pavement
Properties of Polymer Cement CompositeThe binder is more expensive than cementSignifcantly greater tensile strength than unreinforced Portland concrete Similar or greater compressive strength to Portland concreteMuch faster curingGood adhesion to most surfaces, including to reinforcementsGood long-term durability with respect to freeze and thaw cyclesLow permeability to water and aggressive solutionsGood resistance against corrosionLighter weight
