The tensile strength, modulus of elasticity(MOE) and hardness of Pinus massoniana fibers were determined by using zero-span tension and nanoindentation technique.

The strength and modulus of elasticity of matrix increase from almost zero, then at a certain age up to those of the coarse aggregate, and even exceed for lightweight concrete.
