Investigation on Effect of cement Types on the cement hydration and properties of wood-cement composites manufactured from sunflower stalk(Helianthus Annuus)

In this study, the effect of type II and III Portland cement and the use of undepithed and depithed sunflower stalks particles (Helianthus Annuus) with percentages of different mixing ratio of the poplar wood particles (Populous alba) with 100:0, 75:25, 50:50, 25:75 and 0:100 respectively in the man...

Physical and mechanical properties of boards were measured as the effect of lignocellulosic material (sunflower stalks andpoplar wood) and Portland cement type (II and III) on the cement setting time.

In this regard, sunflower stalks particles in comparison with poplar wood particles increased cement setting time intensively.
