Method for preparing epoxy mortar and concrete by using coefficient of linear thermal expansionThe invention relates to a calculating method of a coefficient of linear thermal expansion and particularly relates to a method for preparing epoxy mortar and concrete by using the coefficient of linear ...
concrete. They revealed an increase in the case of polyester resin by 14%, 29%, and 36% for two layers of SFRP, two layers of SFRP with anchorage system, and 4-layers of SFRP with anchorage system specimens, respectively. In the case of epoxy resin, 19%, 45%, and 68% increases ...
In which anchor devices are aligned into the required strengthened member followed by concrete surface preparation for FRP application. Then the FRP strip is installed between the two anchored devices and then a layer of epoxy is applied to the strip. Prestressing then takes place for the required...

Four Hilti epoxy anchors were placed in strategic locations to prestress the concrete to resist shear cracking in the concrete just below the connection surface. A design value for the connection of 50 kips was determined from the data and finite element analyses. Correlations between the design ...
Concrete is assumed to be high quality (f" = 42 MPa), steel is the type currently used in the construction practice (deformed rebars, grade 60), and FRP is made of aramid fibers and epoxy resin with deformed surface (braided). The data relative to FRP follow the recommendations prese...
