A high rate of calcium silicate hydrate conversion observed in Phase II, coupled with lower heat of hydration or exotherm
, yields a finished concrete of higher compressive strength and lower porosity.
The 1st scan data indicate an inflection T of ~38[degrees]C and a residual cure exotherm

This limits the resultant polymerisation exotherm
and thus there may be relatively less temperature rise with PAC.
The polymerization heat, peak and maximum temperature of exotherm
of B-z[(OH).sub.3] is the was lower than benzoxazine (B-o) monomer.
Then it was cooled to 0 [degrees]C at a definite scanning rate and an exotherm
Its low exotherm
also makes it suitable for potting, encapsulating, and casting, especially where wider cross section thicknesses are specified.
Technical Testing Laboratory (Dubai) applied for a licence on 29 June 2010 to use radioactive sources for the purpose of industrial radiography, as mandated by the UAE's Federal Law by Decree No 6 of 2009, Regarding the Peaceful Uses of Nuclear Energy, according to FANR's statement.
