Effects of moisture content on turfgrass forming at room-temperature

In order to study the influence of moisture content on biomass room-temperature forming, forming tests on turfgrass were done in different moisture content and taper with forming bench. The results indicated that density of block varies from small to big firstly, and then to small, accompanying with the increase of moisture content in the same taper; Under a certain moisture content, the density decreases with taper increasing; when moisture content was at 11% and mold taper was at 25°, the density of block reached max-1.10 g/cm3; When raw material moisture content was at 20% or above, the density of lawn grass was smaller than 0.9 g/cm3. The results showed that the density and pressure of biomass had the same trend which was from small to peak and then to bottom with the increase of water content.
