The influence of air humidity on the interaction between VOC and construction materials

Radulescu, C., Chicina, A.

The subject of our study belongs to the large area of studies about the analyze and the prediction of indoor air quality. One of the actual weaknesses for the appreciations of air indoor quality is the lack off knowledge about the interactions between the pollutants and the materials (emission off VOC, adsorption). Knowing the behavior of construction materials we can figure out the possibility off indoor air quality improving.

The study of phenomena present between the humidity, the VOC and the material is based on the masse conservation. The incoming quantity is given by the diffusion phenomenon and by the chemical reactions while the quantity inside the pore is the some off the accumulation in the air of pore, the adsorption on the pore surfaces and the absorption in the condensed liquid.
