Abstract

The countries of the world paid attention to the environment and its concept was related to sustainable development, renewable and clean energy was used instead of traditional energy that polluted the ocean. Ecological materials are one of the solutions used in sustainable development, Compact earth bricks are well-known eco-materials, in this context, we are carrying out a study on bricks made of lime and clay 20*10*05 cm pressed by hydraulic machine, we mix the two components in different proportions to find the best sample in terms of hardness, we add 1%- 20% sawdust for the best sample, we conduct other experiments on the samples to find out the effect of adding sawdust on the compound, we study some mechanical properties of the strongest sample, the results show that adding sawdust increases the hardness by 21%, reduces density by 2.07%, increases Young's modulus by 45% and decreases thermal conductivity by 12%. This indicates the positive effect of adding lime and sawdust to the compressed earth block.
