The Algerian construction industry is facing major challenges, which the authorities in charge of the sector are endeavouring to meet to meet the ever-increasing aspirations and expectations of the country's citizens. These requirements relate to completion times, which need to be optimized, and construction costs that need to be rationalized, without neglecting the imperative of quality in a market marked by strong demand for housing. Added to these challenges is the need to adopt environmentally-friendly, energy-saving solutions. At a time when the presidential program calls for the construction of two million housing units, the search for modern, efficient techniques is becoming a strategic issue for the country. With this in mind, entrepreneur Azizi Mahiou, representative of the Argilor brickworks based in Bordj Bou-Arréridj, is innovating by making available to the housing sector a new technique for insulating clay bricks for rapid, economical and durable construction. It's a salutary innovation," he says, "capable of modernizing the sector and meeting expectations in terms of performance, speed and durability. Whereas the architects and engineers of yesteryear had discovered a healthy material with great insulating properties, we are now rediscovering terracotta in a revolutionary form, technically known as the Monomur brick". Manufactured in Bordj Bou-Arréridj from terracotta, this brick, which our interlocutor presents, not without conviction, as "the material of the future", is distinguished, according to him, by exceptional characteristics. Its intrinsic mineral composition and honeycomb structure make it an innovative product, capable of offering a virtually unlimited lifespan", he explained. "This material acts as a real natural air-conditioner, maintaining indoor temperatures around 24°C in summer, while in winter it retains heat while protecting against humidity. "There's no need for additional insulation. Thanks to its unique thermal performance, Monomur brick is resistant to the spread of fire, acts as a moisture barrier and offers remarkable strength, with a thermal resistance more than 10 times greater than that of a cement wall," explains Mahiou. He adds: "For a single-family home, the shell construction of 100 m2 can be completed in less than 60 days, a record time that changes the game. In a country committed to a vast housing plan, this speed of execution is a major asset. "This technique meets today's requirements in terms of speed, while reducing the costs associated with insulation and air conditioning," he adds. The production of insulating clay bricks is another innovative process. From clay extraction to the final brick, it takes just 48 hours. "After extraction, the brick is fired for 24 hours at a maximum temperature of 900°C, then ground to a perfect finish," he noted. What is known today as zero energy is based on a combination of the thermal qualities of the brick and intelligent architectural design, with ventilation towers that evacuate accumulated heat during the day and cool naturally at night," concluded Azizi Mahiou.
