Analysis of Cement-Modified Structure of Wood-Gypsum Composite

The cement use in the production of wood-gypsum composites to modify their structure leads to an increase in its strength properties. It is therefore necessary to study the structure modification of wood-gypsum composites by the addition of cement in terms of the scientific justification of improving strength properties. The composite structure with and without the cement addition is studied using mercury injection. Purpose: The aim of this work is to determine the pore size and their quantitative distribution in the material structure using mercury injection in wood-gypsum composite samples with and without the cement addition. Methodology: Mercury injection is based on measuring the pressure of non-wetting mercury liquid in the porous structure. Research findings: The obtained results evaluate the wood-gypsum composite structure modified by the cement addition.
