Abstract:
SP-89 A collection of 17 papers dealing exclusively with the various effects of polymers in concrete, this book provides an extensive source of reference material. Presents advances in research, development, and uses of polymers. Case studies cover the effect of moisture on the physical and durability properties of methyl methacrylate polymer concrete; machine application of polymer concrete for highway repairs, commercial applications of epoxies in construction, and polymer concrete for bridge rehabilitation.

Polymer concrete has been used for years to repair portland cement concrete. A monomer system is mixed with well-graded aggregate and placed in the repair area. After the monomer cures, a strong durable material is produced which bonds well to portland cement concrete. Special mixing and placing equipment was developed for a large pavement repair job in Houston. Longi-tudinal cracks, longitudinal lane-shoulder joint separations, spalls, punch-outs, and other types of damage were repaired.

Processes are described for centrifugally applying polymer concrete (PC) liner to straight pipe, for casting the PC liner in pipe fittings, and for closure of field joints. Physical properties of the PC liner materials were measured. Compressive strengths of up to 165.8 MPa (24,045 psi) and splitting tensile strengths of 23.5 MPa (3408 psi) were measured at ambient temperature. Compressive strengths of 24 MPa (3490 psi) and splitting tensile strengths of 2.5 MPa (366 psi) were measured at about 150°C (302OF). Cost of piping a geothermal plant with PC and PC-lined steel pipe is calculated to be $1.21 million, which compares favorably with a similar plant piped with alloy steel piping at a cost of $1.33 million. Life-cycle cost analysis indicates that the cost of PC-lined steel pipe would be 83% of that of carbon steel pipe over a 20 year plant operating life.

Research is reported on the shear transfer between normal concrete and polymer modified concrete. The experimental program was designed to verify the general theory of shear transfer mechanism for concrete and to evaluate the necessary constants of the theoretical expressions. The general theory presented covers structural members with (i) no shear reinforcement, (ii) moderate shear reinforcement and (iii) high shear reinforcement. Four groups of specimens were tested. Group A specimens were used to investigate the relation between intrinsic bond shear transfer capacity and the strength of the composite materials (PMC and concrete). No transverse steel was used in these specimens. Group B specimens contained various amounts of shear reinforcement at the shear interface. Group C specimens were cast monolithically using ordinary concrete to serve as control specimens. Group D were control specimens made up of cast-in-place concrete over precast concrete. They were designed to evaluate the "apparent cohesion" of such elements, for the purpose of comparison with Group A specimens. The investigation will also present the extension of application of the theory to two-layered beams. Results of tests of 16 simply supported beams will be presented, where the principal parameter is the variation of the top PMC layer thickness. The major aspects to be presented are the load-deflection and cracking behavior, the mode of failure of the beams, the contribution of PMC to the strength of the composite beam, the initation and progress of slip in the interface of the two layers, frictional shear resistance of the unreinforced concrete-PMC interface, and the effect of using shear reinforcement to prevent any slip and shear failure.
