“…The cement industries have caused severe damage to the environment. They are one of the primary sources of CO 2 emission into the atmosphere and account for nearly 5% of the global emission [1]. Various studies have confirmed that mineral admixtures can be used to replace cement in concrete partially.…”

The effects of rice straw ash (RSA) and microsilica (MS) on durability properties (water absorption and chloride ion penetration) of M40 grade Pavement Quality Concrete (PQC) were studied. Ten concrete samples were prepared by partially substituting cement with RSA and MS in various proportions. A significant reduction was observed in the water absorption and chloride ion penetration in concrete samples with an increase in the curing age as well as with an increase in the proportion of MS and RSA. The maximum reduction in water absorption and chloride ion penetration was observed in R2M3 (10% RSA and 7.5% MS) as compared to control concrete (R0). The analytical relationships were developed between the above-mentioned parameters and curing age of concrete. A linear equation was established between the initial and secondary rate of water absorption of concrete and also between the chloride ion penetration of concrete at 10–20 mm and 25–35 mm depth. Both these equations were applicable to all the concrete samples of this study. Predictive charts were generated between the above-mentioned parameters and days of curing in water.

“…Oat husks are one of the most common biomass materials in the past few decades. 46 A large amount of oat husk waste is produced every year, most of which is incinerated or left in landfills. In fact, oat husks have a large amount of biosilica with amorphous properties of hydrated SiO 2 grains.…”

“…In fact, oat husks have a large amount of biosilica with amorphous properties of hydrated SiO 2 grains. 46 In the production of porous carbon materials and silicon, it is very meaningful to use oat husks in the near future. When oat husks are carbonized in the hydrogen/argon mixture, carbon-coated SiO x materials can be directly obtained.…”

Silicon monoxide (SiO x ), as a promising anode for the next-generation high-power lithium-ion batteries, has some advantages such as higher lithium storage capacity (∼2400 mAh g –1 ), suitable working potential, and smaller volume variations during cycling compared with pure silicon. However, its disadvantages such as its inherent low conductivity and high cost impede its extensive applications. Herein, we have developed a low-cost and high-capacity SiO x /C@graphite (SCG) composite derived from oat husks by a simple argon/hydrogen reduction method. For further practical application, we also investigated the electrochemical performances of SiO x mixed with different ratios of graphite. As an advanced anode for lithium-ion batteries, the SCG-1 composite exhibits an excellent electrochemical performance in terms of lithium storage capacity (809.5 mAh g –1 at 0.5 A g –1 even after the 250th cycle) and high rate capability (479.7 mAh g –1 at 1 A g –1 after the 200th cycle). This work may pave the way for developing a low-cost silicon-based anode derived from biomass with a large reversible capacity and long cycle life in lithium-ion batteries.

“…One of the solutions to reduce the negative impact of the cement industry on the environment is indeed to partially substitute clinker in Portland cement with pozzolanic materials to produce eco-cement. These pozzolanic materials are either natural materials such as natural pozzolan [2], heat-treated materials such as metakaolin [3] or industrial byproducts such as silica fume and fly ash [4,5] and coal bottom ash [6,7].…”

Durability of Mortar Containing Coal Bottom Ash as a Partial Cementitious Resource

This research work focuses on the study of the durability of composite cements based on coal bottom ash powder produced by SONICHAR in Niger. After a physicochemical and environmental characterization of the coal bottom ash powder, mortar test specimens were made. In these specimens, 10%, 15% and 20% of cement were replaced by identical mass percentages of coal bottom ash powder. Durability studies focused on the determination of the chloride ions apparent diffusion coefficient, the measurement of the depth of carbonation and the accelerated ammonium nitrate leaching. The influence of carbonation and leaching were examined using the following parameters: pore distribution, gas permeability, porosity accessible to water, capillary absorption and electrical resistivity. The results show that the incorporation of coal bottom ash powder into CEM I leads to an increase in the depth of carbonation. This increase is more significant when the substitution rate exceeds 10%. In the leaching test, the partial substitution of coal bottom ash powder in CEM I up to 20% does not significantly affect the durability parameters of the composites compared to the control mortar. Diffusion test shows that for mortars containing less than 15% substitution, there is no significant influence on the chloride diffusion coefficient. A slight decrease is observed for mortar containing 20% substitution.
