Abstract

Composite materials have excellent potential for construction and building applications, especially from an environmental and economic perspective. the need to replace hazardous materials with envitonmentally friendly products is a growing concern worldwide. composites based on natural fibers have become popular because of their superior sustainable features. along with various innovations made in the field of materials. The formation of lignocellulosic using the chorination method in this stage is used 5% NaCIO2 resulting in the formation of white lignocellulose while the addition of distilled water results from the process shows the desired formation of lignocellulose with the formation of fibers, strong tensile strength, colorless. In the processof making bricks, two methods are used, namely the mix sandwich methods. The succes of making lignocellulosic is confirmed through FTIR (Fourier transform infrared) spectroscopy analysis. SEM analysis results show that lignocellulose is in the form of fibers with a size of 50 m. The EDS results showed a C content of 85,265, 78,000 an O content of 11,241, 13,000 EDS spectrum. In the process of making bricks using the sandwich method, they are not homogeneous or even fused. There is an effect of the addition of lignocellulosic material on the compressive strength of bricks. This is indicated by a decrease in the compressive strength of the bricks with increasing lignocellulosic substitution in the bricks.
