Abstract

Current Nigerian housing deficit is estimated at about 17 Million. With rapidly growing urban population in sprawling cities like Lagos, Abuja, Kano and Ibadan, the need to bridge this deficit cannot be more compelling than now. To achieve this, efforts must be directed towards development of alternative and cheaper building and construction materials as roof covering is a major high-cost component of total housing construction cost. This particular study therefore investigated the Engineering Characterization of the Improved Double Roman Tile (IDRT), to evaluate its compressive strength, fire resistance, durability, sound-proof resilience, water resistance and corrosion resistance attribute for possible recommendation for prospective clients and construction specifiers such as architects and building contractors. Prior to this, 18 Nos. of IDRTs (600mm X 600mm) of 4.2kg each were produced using a batch mix of 1 head-pan of Portland cement, 2 head-pans of sharp sand and 4kg of waste paper. The results presented in this paper showed that IDRTs achieved the aforementioned desirable engineering properties with strict adherence to standard operating procedures (SOP) for production. A generalized relationship between unit weight of constituents and product unit weight gave a value of about 1,600kg/m3 compared to 1,700kg/m3 obtained from direct measurements in displaced water volume set up. Taking an average of 1,650kg/m3, the unit weight of IDRT came out lighter than that of standard concrete at 2,400kg/m3. Average 14-day compressive cube strength of IDRT composite mix, came out to be about 1.0N/mm2.The IDRT was also found to be strong enough to withstand a static pressure of 20.0 KN/m2 arising from average static weight of an artisan, without being crushed.
