During the war time every resource is vital. Gaza engineer develops new technology to replace cement. Salameh Bihar, 56, who was displaced after Israel destroyed his house in Gaza’s Shajaiya neighborhood in the recent war, is still waiting to rebuild his three-story house. But he is not optimistic about succeeding.
He explained to Al-Monitor that materials are expensive and difficult to obtain. “The way construction materials are entering Gaza is unfair, a cement unit is worth 27 shekels [$6.70] for affected citizens”. But not all citizens can afford themselves such a luxury.
Imad al-Khalidi explained the process of the creation of the alternative of cement: “We compose a homogeneous mixture by conducting a soil treatment through pressure, to which we add welding natural materials such as potassium carbonate, ground limestone powder and a small quantity of gypsum, to form an initial coherent product in the brick production. Yet, the strong cohesion begins after it is used and continues to solidify for hundreds of years, and to harden dozens of times more than its initial form. This means that the brick increasingly hardens with time, and has its own characteristics.”
