“…In an interesting recently published paper by Tayeh et al [38], nano-powder derived from different wastes at very low percentages (1-3%) demonstrated a surprising improvement of up to 21% in compressive strength. This enhancement was achieved when rice husk (3%), sugarcane bagasse (3%), or cotton stalk (1%) ashes were used in the concrete as cement additives.…”

“…They discovered that the compound could withstand choloride environmental conditions for up to 90 days [37]. In a very recent study, Tayeh et al emphasized that adding 3% sugarcane bagasse ash improved the compressive strength by 18% and 10% after 28 and 90 days of curing, respectively [38]. The enhancement in strength achieved through the addition of sugarcane bagasse ash can be attributed to the amorphous nature of sugarcane bagasse ash particles.…”

On a global scale, millions of tons of diverse agricultural residues are generated annually. Most of these wastes are burned or dumped in landfills, which causes environmental pollution. Addressing environmental issues arising from agricultural waste materials, in addition to mitigating heating and cooling expenses in the construction sector, is an interesting challenge for researchers. The utilization of agricultural wastes in different parts of construction is producing positive findings day by day, and investigating research in this field is a curiosity for researchers. This short study reviewed the most recent achievements in using agricultural wastes as a substitute or additive material for construction. Using these wastes as aggregate, ash (as a supplementary for cement), or fibers for foam concrete, insulation materials, etc. has been reviewed. This review has focused on very recent published papers. Several studies have demonstrated the effective influences of agro-waste materials in construction, like retaining the compressive strength (155 MPa) of concrete at standard levels and reducing heat losses in buildings (69% energy savings for brick insulated using wheat straw), as well as sound insulation. The use of agro-waste materials for insulation positively improved thermal conductivity, costs, and energy savings. However, some wastes did not provide a high added value, which shows that more investigations still need be performed to fill this gap in the research. Considering the global scale of agricultural waste generation and the potential benefits to both the environment and construction industry, continued research in this area is essential.

This paper aims to study the effect of using modified nano‐TiO2 with fly ash (FA) on ultra‐high performance concrete's (UHPC) mechanical, transport, and microstructure properties (UHPC). A ball mill was used to disband the nano‐TiO2 and distribute it uniformly within the FA powder. In this research, 20% of the cement weight was replaced by FA, and nano‐TiO2 was added by 0.4%, 0.8%, 1.2%, 1.6%, and 2% of the FA weight. To investigate the effect of the ball mill period on the UHPC properties, periods of 10, 20, 30, and 40 min were applied to a binder of 20% FA and with 6% nano‐TiO2. In addition, a 30‐min ball mill period on a binder of 20% FA and 0.4%, 0.8%, 1.2%, 1.6%, and 2% nano‐TiO2 was also investigated. Tests of compressive strength after 1, 7, 28, and 91 days of curing in tap water, splitting tensile strength, flexural strength, and modulus of elasticity were performed after 28 days of curing in tap water. Tests of chloride permeability, sorptivity coefficient, water permeability, and microstructure were also performed after 28 days of curing in tap water. The results showed that the addition of higher percentages of nano‐TiO2 led to a decrease in workability. The addition of nano‐TiO2 improved the mechanical properties. The highest compressive strength of 208.9 MPa was achieved for the mixture of 20% FA with 1.2% nano‐TiO2 at the age of 28 days. The 30‐min period of application of the ball mill achieved the best performance compared with the other periods. The results of using a ball‐mill to re‐mix nano‐TiO2 between 1.2% and 2% by weight with FA showed impressive comparative results.

“…However, the introduction of nanosilica particles may result in deterioration of the properties of cement-based materials [13]. For example, Tayeh et al [14] suggested that the incorporation of nano agriculture waste decreased the workability of ultrahigh-performance concrete. The workability of slurry may be reduced due to the high specific surface areas [15] and agglomeration trend of nanosilica particles, which contribute to adsorb a great amount of water [4].…”

The agglomeration trend of nanosilica particles was found to significantly affect the properties of cement-based materials. The influence of nanosilica suspension on the fluidity, setting time, and compressive strength of cement-based grouts were studied. The hardened pastes were characterized by thermogravimetric (TG) analysis and scanning electron microscopy (SEM). The results showed that the fluidity of cement-based grouts with nanosilica suspension had obviously improved. The setting time was obviously decreased, compared with the reference sample. The compressive strengths for 1 day, 3 days, and 28 days were 12.8%, 14.3%, and 10.1% higher than that of the reference group, respectively. This paper may provide a novel route to improve the mechanical properties of cement-based materials without affecting their workability.
