Mycelium growing in the loose agricultural waste materials can form a network that wraps these waste materials, it is in this way that mycelium materials with certain mechanical strength can be prepared.
However, the mechanical strength of such materials can be further improved with the use of a polymer network.

The present paper focuses on the extensive use of basalt and carbon fiber (Uni-directional) reinforced materials.
The physical properties of thermoplastic materials vary because of ambient temperature.
Hardness is used to determine the relative hardness materials, usually plastic or rubber.
The use of epoxy as matrix and adding of different materials with better properties increases mechanical properties.

The durability of building materials is very sensitive to humidity and both high and low mc, and rapid changes may damage the materials and decrease their performance.
A better understanding of moisture transfer can therefore reduce or prevent damage in building materials.
The range of the values remain coherent with the concerning materials.

Fig. 5 Sand washing device Fig. 6 Belt linked with washing device Fig. 7 Conveyor belt Displacement of fine materials after washing After finish washing process for sand (15 minutes), the mixture move (sand and water) to spiral seeded device Fig.8, device works on displacement the fine materials in a collection tank while course materials (+600 µ) will collect it in upper of the device because the spiral motion toward the upper.
It allow for materials to pass through it, entering of sand should not exceed 50% solid according to the operating instructions of the device.
The second stage is the mechanical attrition scrubbing process of the sand grains to clean the surfaces of the materials adhering in it and cannot be removed by washing.
