Properties of hemp fibre reinforced concrete composites

This research is concerned with the mechanical and physical properties of hemp fibre reinforced concrete (HFRC). An experimental program was developed based on the statistical method of fractional factors design. The variables for the experimental study were: (1) mixing method; (2) fibre content by weight; (3) aggregate size; and (4) fibre length. Their effects on the compressive and flexural performance of HFRC composites were investigated. The specific gravity and water absorption ratio of HFRC were also studied. The results indicate that the compressive and flexural properties can be modelled using a simple empirical linear expression based on statistical analysis and regression, and that hemp fibre content (by weight) is the critical factor affecting the compressive and flexural properties of HFRC

Cellulose Composites for Construction Applications

This chapter reflects the key tendencies of cellulose fiber composites for construction applications. These materials represent an alternative to traditional materials in the construction industry that will be reflected in energy savings and emissions control, increasing the opportunity for recycling and reuse of building materials. Cellulosic fibers are commonly used to manufacture  packing bags for  agro-industry products, ropes, threads and handicrafts.  Further research development to extend the use of these fibers in the construction sector is an issue of great worldwide importance because the construction industry uses large quantities of raw materials.Fil: Gómez Hoyos, Catalina.
