Abstract
In the modern day, priority is given towards cheaper and economically more viable options in the construction industry, this is often caused by the high cost of classic building materials. The composite materials which are often used, contain not only inorganic but organic chemicals that give them certain properties such as tensile and adhesive strenght on top of making them economically viable, their production is generally cheaper and it produces the same quality products as classic materials but with downside of being more complex. Modern composite materials often use cellulose as a component, it is to be noted that cellulose has various modifications, these modifications often fulfill different roles, one of which is hydrophobic additions, which fulfill their roles in damp and moist enviroment, because of this they are often used in areas with high moisture percetege in the air.
Hydrophobic additions are quite expensive too, their main function is to create a micelle which is stable and has ability to repel water. In addition to previous paragraph, attention is also given to strength of the material, however in composite materials this is exceedingly difficult when compared to creating a hydrophobic material, this is due to the fact that tensile strength of a composite materials is determined by many other factors, one of of which is the size of particles, strength of chemical bonds etc.To solve the following issues we conducted research with various silicates that posses the desired properties which might improve the composite materials.
During testing tetraetoxisilicate and ethylsilicate was added into the various composite materials, this addition was direct and by form of treating already finished material, the optimal mixing method was detetmined by testing of applied material for adhesion results, with this method it was determined that the optimal method of mixing the research materials was to mix them simultaniously.
