Abstract
Oil Palm Shell (OPS) concrete can be used in different fields of construction.
To determine more accurately the fields of application, it is important to
know and understand the behaviour of OPS concrete over the long term and
when it is in aggressive environments. This paper presents the results of studies conducted on the durability of OPS concrete. Water absorption capacity,
electrical resistivity and apparent diffusion of chloride ions have been measured on different concrete samples. In addition, the behaviour of OPS concretes to carbonation was studied in an environment rich in carbon dioxide.
Results show that OPS concrete has an absorptivity of 0.97 kg/m2
·h1/2, an
electrical resistivity of 64.37 Ω·m and an apparent diffusion coefficient of
chloride ions of 3.84 × 10−12 m2
/s after 90 days. All these results of OPS concrete are very close to those of concrete with normal aggregate and other
lightweight concrete, which mean OPS concretes have globally good properties with regard to durability.
