AbstractAbout AuthorsReferences
Within the framework of this paper, gypsum composites of different densities and strengths were obtained. The influence of different hydrophobizers on the softening coefficient of gypsum composite reinforced with plant filler was investigated. The crushed stem of Sosnovsky’s hogweed was used as a plant filler. The plant filler was pre-dried, treated with organosilicon hydrophobizers by irrigation method followed by powdering with gypsum binder. From the obtained mass, 4х4х16 cm specimens were fabricated. The pressing pressure was varied from 0.2 to 0.8 MPa. The density, flexural strength, compressive strength, and softening coefficient were determined for the obtained specimens. Increasing the pressing pressure increases the density and strength characteristics of the gypsum composite. Modification of the plant filler did not affect the density and strength of the composite but allowed 1.3–2.3 times to increase its water resistance.
