The microstructure of the LFC was also examined using the scanning electron microscopy (SEM) technique. Furthermore, the results of the present study encourage the reuse of industrial by-products in the production of sustainable construction materials and thus can be considered as a potential solution for industrial solid wastes treatment.

This study aims to investigate the long-term mechanical properties and durability of cementitious composites (CC) with low polypropylene (PP) fiber content and local river sand. The CC samples were prepared with different water-to-binder (w/b) ratios (0.20, 0.25, and 0.3), low PP fiber content (0.6% by mass of binder), locally available river sand, and fly ash (FA) sourced in the Mekong Delta region, corresponding to the mixture name WB20, WB25, and WB30, respectively.

Engineered cementitious composite (ECC) creates many potential civil engineering applications due to its outstanding ultimate tensile strain capacity (normally exceeding 2%) compared to conventional concrete and fiber reinforced concrete. The high tensile ductility of ECC is mainly influenced by fiber characteristics.

The recycled steel fibers from waste steel cables have properties suitable for enhancing the load-bearing capacity, impact resistance, and shrinkage reduction of Self-Compacting Concrete (SCC). The use of a high content of fly ash in SCC reduces production costs and is environment friendly by minimizing the amount of cement in the mix. This article presents the experimental research results on the influence of the content of recycled steel fibers on the properties of high-fly-ash SCC.

The effect of maleic anhydride grafted polypropylene (MAPP) on mechanical properties of bamboo fiber mat reinforced polypropylene composites (BMRPC) was studied. The results showed that mechanical properties of the composite depend on the amount of MAPP and those attained maximum values at 6 % MAPP. The effects of bamboo fiber mat contents on mechanical properties were also investigated. Maximum values for the tensile, flexural and impact strengths of BMRPC were obtained at a bamboo fiber mat content 45% (by weight).

Cotton bamboo fibers were prepared by mechanical method and their diameter were about 9- 26 µm. Surface composition and morphology of fibers were studied. The analytic result shown that most of hemicellulose and lignin were removed. There is a strong and sharp peak in the untreated bamboo spectra at about 1736 cm-1 corresponding to carbonyl group (C=O), but this peak disappeared in alkaline treated bamboo spectra. Epoxy composites reinforced cotton bamboo fiber have been developed with varying fiber contents.

This paper presents the results of the effect content of short bamboo fiber prepared by mechanical method and alkaline treatment on mechanical properties of polymer composites (PC) based on polypropylene (PP). With content of 50% in composition, the tensile, the flexible and impact strengths have been increased as 24%, 23% and 40%, respectively in comparison with original PP. Using the prepared bamboo fiber by steam explosion method in stead of mechanical one, the tensile strength of composite increases 16%, mean while the flexible and impact strength have the equivalent value.

This paper showed the effect of acetylation of bamboo surface by anhydride acetic (AA) on tensile strength of polymer composite (PC) based on polypropylene (PP) reinforced by short bamboo fibers. The best conditions for acetylation is ratio of –OH to AA was 1:3, at the temperature of 100o C within 8 hours. The tensile strength of 50% fibers content’s PC has been increased in comparison with unreinforced PP.
