Abstract
Results of an experimental evaluation of nano/micro inorganic composites are presented in this paper. Alkali alumino
silicates matrices reinforced with nano/micro fibers were used to repair (glue) fractured concrete prisms and test them in
three point bending. Further, shear strength of matrices were also obtained using push-up tests. The variables evaluated
were mix composition, temperature and specimen size. It is observed that flexural tensile strength of 1000 psi can be
achieved from the developed matrices. In some instances when repaired broken prisms were tested, the failure occurred
by creation of a new fracture surface. The developed matrices had the fluidity to fill very thin delamination, which can
be pumped to reach delamination through small drilled holes. The results show that the compositions obtained in this
study have excellent potential for application involving the repair of delamination.
