  • conceptualisation and pilot study of shelled compressed earth block for sustainable housing in nigeria
    International journal of sustainable built environment, 2014
    Co-Authors: C Egenti, Jamal M. Khatib, David Oloke
    Abstract:

    Abstract Meeting the housing needs in Nigeria is a long-standing task, yet to be realised. The economy of the country, as most developing countries, is ailing with limited resources. Energy and infrastructures are inadequate, yet the use of Cement dominated the construction industry. Earth construction is a sustainable option to housing with inherent characteristics that should be desirable in the ailing economy of hot tropical environment in Africa. However, most Nigerians are skeptical of taking a low cost option with less modern effects and uncertain durability. This research explores the issues relating to this problem and aims to bridge the gap between Nigerians and earth, which exists in abundance in Africa. The emerging concept from the survey of public reaction to earth construction in Nigeria is of a shelled compressed earth block (SCEB) of an inner core of ‘earth’ with less Stabilisation and an outer shell of the same earth composition but with higher ratio of Cement Stabilisation for adequate durability, compressed into a single piece. A mechanical kit was designed and fabricated for the production of sample shelled compressed earth block for laboratory tests. Basic preliminary tests were conducted on the model and results revealed that the concept was feasible thus paved the way for further research work in shelled compressed earth block (SCEB).

  • sorption characteristics of stabilised soil blocks embedded with waste plastic fibres
    Construction and Building Materials, 2014
    Co-Authors: C K Subramaniaprasad, Benny Mathews Abraham, E Kunhanandan K Nambiar
    Abstract:

    Abstract This paper highlights the results of an experimental investigation, on the Sorption Characteristics of plastic fibre reinforced soil, done to study the possibility of utilisation of waste plastics in soil masonry blocks. Cylindrical specimen of raw soil and modified soil were prepared by compacting at different moulding pressures and were tested for sorption characteristics. Raw soil is modified by adding varying percentage of stabiliser (Cement: 5%, 10% and 15%), fibre types (made out of mineral water bottles and carry bags), fibre lengths (1 cm and 2 cm) and fibre percentages (0.1% and 0.2%). The sorption characteristics of mud blocks have been studied by measuring Water absorption and Sorptivity. Water absorption of samples with 10 - 15% Cement Stabilisation was less than the value specified by IS 1725-1982. The combination of mechanical and chemical stabilization without fiber addition has resulted in a reduction in sorptivity. But fiber addition increased the sorptivity.
