Abstract
Libya is one of the largest producers of dates from date palm, generating about
60000 tonnes of date palm seeds (DPS) annually. This large amount of seeds led
to studies into the possible use as aggregates in lightweight concrete for some
special structures. The utilization of DPS as aggregate in concrete provides a
good solution as alternative aggregate to the stone aggregate. It has been
recognized that, DPS can be used as coarse aggregate in structural lightweight
concrete industry. For any structure member, the durability is one of the most
important considerations during its service life. This paper presents the durability
properties of DPS concrete. These include the water permeability, water
absorption, sorptivity and chloride penetration. The test results obtained were
comparable to the conventional lightweight concrete.
Keywords: date palm seeds, lightweight concrete, durability, sustainability,
permeability of concrete, water absorption of concrete, sorptivity of concrete.
1 Introduction
Engineers have been developing new technologies for sustainable materials in
the construction industry. One of such technologies is to use waste materials as
building materials. DPS is a renewable resource and therefore, has significant
potential in the construction industry where date palm is in abundance. This is
particularly so in Libya. Currently, the large quantity of DPS waste has led to
studies focusing on the possible use of this waste as aggregates in special
structural lightweight concrete.
It has been reported that the concrete industry globally would consume
around 8 to12 billion tones annually of natural aggregates after the year 2010 [1].
