abstract = "Cement-based adhesive (CBA) is used as a bonding agent
in Carbon Fibre Reinforced Polymer (CFRP) applications
as an alternative to epoxy-based adhesive due to the
drawbacks of the epoxy system under severe service
conditions which negatively affect the bond between the
CFRP and strengthened elements. This paper reports the
results of, an investigation carried out to develop two
types of CBA using magnetized water (MW) for mixing and
curing. Two magnetic devices (MD-I and MD-II), with
different magnetic field strengths (9000 and 6000
Gauss) respectively, were employed for water
magnetization. Different water flows with different
water circulation times in the magnetizer were used for
each device. Compressive and splitting tensile strength
tests of the magnetized CBA (MCBA) were conducted for
different curing periods (3. 7, 14, 21 and 28a days)
using MW. It was found that MW treatment increases the
strength of CBA. The highest strength was obtained for
MCBA samples when MD-I was used at a low flow rate (Fa
=a 0.1a m3/hr) for 15 mins of circulation time (T). The
latter was found to positively affect MCBA properties
when T was increased from 15a min to 60a mins.
Prediction of the compressive and tensile strength
values are also studied in this paper using genetic
programming, the models showed good correlation with
the experimental data",
