Due to its evolving technology and dynamic nature, a sizeable segment of the world’s construction market that used to partly rely on traditional site-mixed concrete (SMC) had almost completely shifted to ready-mixed concrete (RMC) several decades ago in the developed countries. Likewise, this targeted trend has been observed in developing countries. The Egyptian residential sector has also adopted some corrective changes in this direction in the last decade. Nevertheless, the vast majority of builders in the Egyptian market have continued to oppose to this global paradigm shift. The observed “cultural” resistance to change seems to be chiefly driven by the difference in the unit price of SMC and RMC, overlooking the latter’s superior characteristics and its added values that fundamentally overweigh this apparent difference in cost. This survey-based study aims at promoting the use of RMC over SMC for construction of new residential communities in Egypt. A mixed (qualitative and quantitative) approach was used in this survey. A customized survey, comprised of a series of interviews with consultants/contractors in the field and a detailed questionnaire targeting practitioners, was conducted to gage market responsiveness to the desired change. The targeted market shift towards RMC hinges on generic variables: price, concrete quality and customer satisfaction, and market-specific variables: local concrete culture, perception of average customers, and permitting process.
