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 64.37Ω·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.
