Abstract
A total number of 18 standard concrete cylinders were manufactured and tested in this 
study under axial static compression loading, to assess the influence of CFRP 
confinement on their performance. The specimens were divided into two groups 
according to two cement grades used. Each of the two Groups consisted of 9 concrete 
cylinders, eight of which were CFRP fully or partially confined. The last cylinder of 
each group was without CFRP wrapping, used as control specimen for comparison. The 
used CFRP strips were from two different Sources (1) and (2) applied to cylinder surface 
using either one of two epoxy resin Sources (a) and (b).
 Two systems of the application of CFRP with epoxy resin were adopted. System (1) 
using CFRP Source (1) with epoxy resin Source (a). System (2) using CFRP Source (2) 
with epoxy resin Source (b). Each application system was adopted for 8 cylinders using 
each of the two cement grades. Four schemes of CFRP wrapping, either fully or partially 
confined, were used. 
 Based on obtained test results, conclusions are presented regarding the parameters 
affecting the ultimate compressive load of tested concrete cylinders, which are the 
cement grades chosen, the CFRP confinement schemes adopted, and the epoxy resin 
types used.
