Physical and Mechanical Properties of Gypsum-Like Rock Materials

determination of some physical and mechanical properties red bean

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...

effect lignocellulosic materials on hydration process, vicat and mechanical properties of gypsum bonded particle board

gypsum-bonded particleboard panels were made from various mixture of bagasse (saccharum ossicinarum l.) and wheat (oryza sativa l.) straw particles bonded with different ratio level of particles/gypsum. this study examined possible feasibility of bagasse and wheat straw particles in the production of gypsum-bonded particleboard (gbpb). one-layer experimental gbpb with density of 1.05 and 1.20 g...

Palm kernel fruit fiber reinforced gypsum-cement based wall panels: It’s physical and mechanical characteristics

Agricultural waste fibers have been found to be suitable as reinforcement in cement-based composites, but studies on oil palm fiber as reinforcement in gypsum-cement wall panels are scarce. A mixture of two equal weights of gypsum and cement, with water-binder ratios of 0.45 and 0.55 were prepared. In each mix a varying percentage of fiber contents of 2%, 3% and 4% by weight of the binders were...
