PENGARUH PENAMBAHAN SERAT POLYPROPYLENE TERHADAP KUAT TEKAN FOAM CONCRETE
Abstract
Lightweight concrete has a specific gravity of 400 - 1,600 kg/m3 so it has a lower weight than normal
concrete. One type of lightweight concrete is foam concrete which is formed by adding air to the concrete
mixture. The compressive strength of foam concrete is still very low. With the addition of polypropylene
fibers can increase the compressive strength of the concrete. The value of the compressive strength of
foam concrete with a mixture of 0% polypropylene fiber shows a value of 2.85 MPa. The addition of 0.2%
fiber showed a value of 7.77 MPa. The percentage of 0.4% polyoropylene fiber has a compressive
strength of 8.38 MPa.
