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 done
in this study which can speed up the cycle of making concrete. This is advantageous in the production
of 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 made
with 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% of
compressive 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.
Key word : concrete, fly-ash, steam curing
