Experimental program Materials and mix proportions The cement used in experiments was ordinary Portland cement with grade P.O 42.5 came from Ningxiang cement Plant, and related parameters are shown in table 1.
These results demonstrate the value of admixture A additives for the durability of materials in aggressive environments.
For the materials and testing procedures used in this study, it was found that steam-cured concretes from OPC and admixture A mixes were more porous as indicated by the much higher sorptivity values compared to the 28-day standard-cured specimens.

The paper analyzes the tensile behavior of some new biocomposite materials based on polypropylene reinforced with hemp shives for different volume fractions and sizes.
The analyzed materials are new materials based on renewable and recyclable resources and from this point of view these materials have a less harmful impact on the environment compared to the conventional composites.
By analyzing the tensile properties of polyproylene based biocomposites reinforced with hemp shives it can be observed in which way these materials could replace conventional materials in various fields of applications.
