Abstract:

 Recovering today to earthen construction techniques in many countries has led to the development of various earth block production techniques, including the clay mud block casting technique. Furthermore, the maturation in water is an essential step in developing cementitious matrix materials because it allows an improvement in performance due to the crystallization of a large amount of cement. However, the best maturing method has not been identified for clay-cement blocks produced by this casting technique. Thus, this research aims to revisit this technique and improve blocks' mechanical performance by proposing the adopted maturation method. Clay mud blocks containing 8% cement and rice straw contents varying between 0 and 1% (mass proportion) were made. They were divided into three-part and exposed to three different treatments. The first part was made to mature at room temperature in a room for 25 days. The second part was made to mature in water for 20 days and then dried for 5 days in the same room. Finally, the third part was matured under a tarpaulin for 20 days and then dried for 5 days in the room. These blocks' flexibility was tested under dry and wet conditions. Similarly, their water absorption and swelling were measured. Blocks that have matured at room temperature dissolve totally or partially in the water, while those that have matured in water and under a tarpaulin remain stable. In addition, fibers generally increase water absorption and blocks swelling. They also increase blocks mechanical resistance because of their distribution and adherence to the clay-cement matrix. Finally, the best bending strengths are achieved with 0.8 % fiber with blocks that have matured in water. The maturation in water increases the bending resistance and reduces the swelling of the blocks in water more important than the maturation under a tarpaulin. Similarly, maturation under a tarpaulin allows greater performance improvement than maturation in air. [.
