Their reinforcement mechanism lies mainly in the formation of hydraulic cohesive material in hydration and carbonation. The sodium bicarbonate and waste iron-dust show a better reinforcement effect.
其增强作用主要表现为水化反应产生的水硬性胶结物或碳化作用，试验表明小苏打和铁粉具有较好的增强效果。
Cohesive soil with high liquid limit is not suitable to be used as fill material for road beds.
高液限粘土不适宜作为路基的填筑材料。
A cohesive arch occurs when particle-to-particle bonds form, allowing the material to pack together and obstruct flow.
当形成粒子对粒子的粘连，从而使材料粘成一体并阻碍流动时，粘连弧形就出现了。
