ABSTRACT

In addition wood powder residual sawmill.the concrete will cause a change in behavior
juxtaposition between concrete and reinforcement steel reinforcement material either plain or
reinforcement thread.The research this studyFiber is used sawmill waste wood fiber with content
0%, 0.5%, 1% and 1.5% of the volume of concrete as a comparison is also made of concrete
without fibers.
Specimens used were silinder30 cm x 15 cm were 12 specimens for compressive strength
testing and 24 specimens for testing strong adhesion. By using reinforcement thread diameter D
10mm and 10 mm reinforcment glace.
From the research of the study isstudy iscompressive strengthwith a mixture of sawdustdeclines
with the powder in each variation the capability of strong stickbetween reinforcing steel and concrete
plain wood fiber and strong adhesion between reinforcment glace stee land concrete screw wood
fiber show that the strong ability adhesion reinforcment thread more thanreinforcment glace.While
more of fibers in the concrete mix variation, the lower the magnitude of the strong adhesion between
the concrete and reinforcement plain tacky.
