At the same W/C condition, ocean-sand (standard and non-standard) is mixed, non-standard ocean-sand shall have more compressive strength than standard ocean-sand about 10%, Add slag additament to motor test sample of ocean-sand mixing, bending strength shall be according to slag additament, but 40%~60% slag additament shall be quite obvious. Motor test sample of ocean-sand mixing shall be compared type Ⅰ cement with type Ⅱ cement, to make use of type Ⅱ cement to motor test sample of ocean-sand mixing shall have more compressive and bending strength about 10%, Rising of strength is best among non-standard sand mixing.

若添加炉石於海砂所拌和的水泥砂浆，其抗弯强度会随著炉石添加量的增加而增加，以40%~60%的炉石替代量为最佳；以第Ⅰ及第Ⅱ类型所拌和的海砂水泥砂浆试体做比较，依晚期强度而言，第Ⅱ类型水泥所拌和的试体，其抗压及抗弯强度比第Ⅰ类型水泥约高出10%左右，其中以非标准砂所拌和的试体强度上升最大。

The strengths of the plain wood rose along with the compression ratio, while the bending strength and MOE lowered as it reached the maximum compression ratio; the plain wood compressed (33%) and heated 10h with 180℃. its bending strength lowered 40%, MOE lost about 50% and hardness lowered 12% than heated 0.5h; the properties not to be compressed after impregnated with PF resin. had a slow rising with the resin concentration, and compressed (33%) after impregnated with PF resin (30%). its bending strength, MOE and hardness increased 82.9%, 98% and 152% respectively.

三倍体毛白杨素材压缩后，其静曲强度和抗弯弹性模量均随压缩率的增大而提高，但接近最大压缩率时均下降；素材压缩（压缩率为33%）后以180℃空气加热处理10 h，静曲强度比同温度压缩保温0.5 h时下降约40%，抗弯弹性模量下降近50%，表面硬度下降约12%；用PF树脂浸渍处理后不经压缩，随PF树脂含量增加木材静曲强度提高幅度不大；用30%PF树脂浸渍后，当压缩率为33%时，其静曲强度、抗弯弹性模量和表面硬度分别比未压缩素材增加82.9%，98%和152%。
