Abstract
With the arises of environmental conscious, the usage of vertical garden system has become more popular in urban cities. Citizens can enjoys the benefits of energy and cost saving besides ornamental effect. More investigations have been conducted on green facades led to the cities ecological enhancement.However, limited plants species can be planted for green facades systems as this system does not provide sufficient soil and nutrients for common plants. Alternative plantation methods such as planted box and felt system required additional maintenance attention. The idea of using clay composite which consists of nutritious soil, water absorbing polymer and flexible cement clay potentially become alternative vertical greenery systems that offers economic and sustainable plantation platform for more variety of plants.The fabricating of clay composite involved three processes, they are: mixing, moulding and drying. Physical properties characterisation (density, pH, compression test, aging test and water immersion test) were tested on the dried fabricated clay composite to ensure their sustainability in tropical climate. The results showed that clay composite with 1.5 wt% of cement and 0.3 wt% superabsorbent polymer shows optimum water absorbing properties. This system are expected to enable more agriculture activities in urban living.
Highlights
Using plants and greenery is an ecological solution to reduce ambient temperatures, mitigation of urban heat island effect and building energy saving [1]

We study the effect of cement content in clay composite on water absorbing properties
Summary
Using plants and greenery is an ecological solution to reduce ambient temperatures, mitigation of urban heat island effect and building energy saving [1]. Plants on vertical landscaping absorb dust and clean air, and in this way they work as natural air filtration [2,3]. The use of plants offers natural advantages as plants are clean source and it has the ability to control noise and use as barriers for noise abeyance [4]. The development in vertical greenery system is emerging, as a results of limited green area in developing cities and growing of environmental consious. Installment of vertical greeney system are receiving encouragement from authorities. The German Jugendstil movement (Art Nouveau) from the early 20th century encouraged the integration of the house with the garden and emerged some incentive programs for the installation of green facades [5]
