“…Generally, cement hydration products always have irregular shapes and randomly agglomerate, resulting in the formation of disordered microstructures [12,13,14]. The main solution for reducing the cracks of a cement matrix still mainly depends on filling various fibers and nano mineral materials [15,16,17]. These fibers and materials cannot control the shape and aggregate state of cement hydration products; the irregular agglomeration of the cement hydration crystals with an irregular shape inevitably produces many cracks and holes in the cement matrix.…”

The main problem with cement composites is that they have structural defects, including cracks, holes, and a disordered morphology, which significantly affects their strength and durability. Therefore, the construction of cement composites with defect-free structures and high strength and long durability is an important research topic. Here, by controlling the size and chemical groups of graphene oxide nanosheets (GONs) used for doping, we were able to control the entire cement matrix to form an ordered microstructure consisting of polyhedron-like crystals and exhibit flower-like patterns. The cracks and holes in the cement matrix just about vanished. The compressive and flexural strengths as well as the parameters for the durability assessment of the corresponding cement composites obviously improved compared with the control samples. Thus, the formation mechanism of the cement matrix with the ordered microstructure is proposed, and a proper explanation is given to regulation action.

“…The results showed that reinforced mortars exhibit a significant increase in flexural strength compared to the reference mortar. Al-Tulaian et al [4] found that the incorporation of 1.5% (by volume) of PET fibres 50mm long in mortars led to the highest increase of 85% in flexural strength compared to that of the control mortar.…”

The environmental awareness has prompted the construction industry to develop sustainable materials. Fibrereinforced composites are considered a pontential alternative to improve the durability of construction materials. These additions may also increase the deformation capacity and the energy absorption of the composite. Besides increasing the coating durability, recycled fibres may promote environmental gains. This paper presents a review of the researches done with recycled fibres, both synthetic and natural, and discusses fibre characteristics, properties and treatments to improve the performance of the composites. Therefore, considering previous studies, this work intends to analyse the incorporation of different kinds of recycled fibres to achieve better performance of cement mortars in terms of cracking resistance, impact strength and durability, without significant decrease in mechanical strength and water absorption. This article also intends to characterise the feasibility of the incorporation of waste fibres in cement mortars that could reduce their modulus of elasticity and increase their deformation capacity, to improve their resistance to cracking, based on previous works of the literature. The results suggest that the fibre incorporation provides an improvement in the cracking performance of the mortars. Parameters as length, type and treatment of the fibres are meaningful.

“…Some of waste materials has been used as fibers reinforcement in concrete structures. Study on the use of plastic fibers as concrete reinforcement has been conducted by researcher (Tulaian et. al, 2016), they found that the recycle plastic (RP) ratio of 1.5% with concrete in the beam had the highest flexural strength.…”

Flexural strength of concrete beam with 0.4 water-cement ratio made with waste long cans fiber and silica fume are investigated. 15 sample of concrete beam has been casted and tested for this research. The long cans fiber of 250 mm long, 10 mm wide and 1 mm thickness with various fiber directions of 0 o , 0 o + 90 o , 0 o + 45 o are used. The results show that by inclusion of cans fiber produces the flexural strength of 8.3 MPa for sample S1 which is higher 5.5 % compared to control sample S0. A comparison between fiber directions indicated that fiber direction of 0 o (S1) produce the highest flexural strength while sample S2 is the lowest flexural strength due to the presence cans fiber with 90 o direction cannot increase the strength, even reducing the concrete beam strength.. However Sample S2, S3 and S4 produce lower flexural strength compared to control sample. This might be due to de-bonding effect between two layers of drink cans fiber that result premature failure on the beam.
