PEMAKAIAN FLY-ASH SEBAGAI CEMENTITIOUS PADA BETON MUTU TINGGI DENGAN STEAM CURING (THE USE OF FLY-ASH AS CEMENTITIOUS ON HIGH-STRENGTH CONCRETE WITH STEAM CURING)
ABSTRACT: The use of fly-ash
as cementitious will be made to utilize physical and chemical properties of fly-ash
that has a dominan of silica and good of modulus fines. The use of steam curing
will be donein this study which can speed up the cycle of making concrete. This
is advantageous in the productionof precast concrete and velocity field
construction.
The research was conducted by making concrete cube 15x15x15 cm for 80
pieces and then tested the compressive strength and absorption of concrete.
Achieve the quality of concrete madewith the provision of K600 with giving the
fly-ash respectively 7.5%, 15% and 30% by weight of cement.
The results of the research obtained by the use of fly-ash as much as
7.5% as a cementitious that was given to the steam curing will provide the
initial strength of concrete reached 47% ofcompressive strength at 28 days.
While the effect of giving fly-ash in concrete has not seen absorption significantly
when compared to concrete without fly-ash.
