“…This calcium carbonate continuously manufactured by the bacteria, urea, and calcium chloride provided as organic precursors makes the internal structure of concrete more compact. The rise in compressive strength is in agreement with the results obtained by 3,[31][32][33][34][35] confirm that the bio-healing is a cause of compressive strength improvements in opposition to normal gross aggregates, these improvements may be related to a smaller wood ash units scale. This permitted better packing and the concrete matrix's compaction around them, which gave these specimens much more strength than control specimens 10 .…”

Novel carrier units were evaluated for their bio-healing benefits in our study to increase the efficacy of concrete healing. Bacillus cereus MG708176, an alkali-tolerant, calcite precipitating, endospore-forming strain was added as a bio-healing agent after its immobilization on wood ash units. A spore concentration of [1.3 × 107 spore/cm3] combined with 2.5% w/w urea was added to cement. Beams of 40 × 40 × 160 mm were used and tested for completely damaged mortar specimens after 7, 14, and 28 days of water treatment. Using wood ash bacterial mortars, totally destructed specimens were fully healed in all time intervals. Positive changes in concrete mechanical properties in bacterial wood ash treatment that were 24.7, 18.9, and 28.6% force for compressive, flexural, and tensile strengths more than control. The micro-images of the Scanning Electron Microscope (SEM) showed the dense concrete structure via calcite, Bacillafilla, and ettringite formation. Our results have shown improvements in the concrete healing efficiency and the mechanical concrete properties by filling the concrete cracks using a calcite-producing bacterium that is immobilized on wood ash units.

“…Therefore, from the results of the slump test and the air content test, it can be said that WBA concrete has a slump and air content without any problems in construction. These facts are consistent with those described in [7,15,16].…”

“…As reported in [7,15,16], woody ash mixed into the concrete may absorb water and the workability of concrete may decrease. Therefore, when woody ash is mixed into the concrete, it is necessary to increase the unit water volume in concrete in order to achieve the same level of workability as normal concrete.…”

In recent years, the woody biomass power generation has attracted a lot of attention since woody biomass is an alternative energy source to fossil fuels. In the future, further implementation of woody biomass power generation is expected, and a large amount of woody ash will be discharged. Several studies have been conducted on the effective use of woody ash for construction materials. However, woody ash has not been practically used because of concerns about the leaching of heavy metals from concrete mixed with woody ash. If the above problem can be solved, a large amount of woody ash is expected to be used. In this study, the fresh property and hardened properties, such as compressive strength and length change were measured to evaluate the feasibility of using concrete mixed with woody ash. Furthermore, a heavy metal leaching test was conducted to assess the environmental impact caused by concrete mixed with woody ash. As the result, the concrete mixed with woody ash has the slump and air content similar to that of normal concrete, the compressive strength meeting the standard durability design strength in Japan, and the shrinkage is similar to that of normal concrete. Additionally, the concentration of heavy metals exceeding the soil environmental quality standards in Japan was partially detected, but the leaching amount of heavy metals from the concrete mixed with woody ash was similar to that from normal concrete.

“…Saw dust had limited cementitious value on its own. Still, when combined with water, it chemically interacts to generate cementitious compounds, which contribute to the increase of soil compressibility and strength parameter [10]. Silica is the prime component of saw dust ash (SDA), and it is responsible for the ash's reaction.…”

Rapid urbanization and construction are driving up the consumption of cement and aggregate used in building construction. However, the manufacture of cement and concrete boosts carbon dioxide emissions and depletes the supply of natural aggregates. As a result, alternative materials for building construction are required. A replacement material, saw dust ash (SDA), is obtained from woodfired power stations, pulp, paper mills, and other wood-burning factories. However, the SDA manufacturing sector necessitates enormous tracts of land in rural locations. As a result, some wood waste is sprinkled throughout the open land, while others are burned in incinerators, contributing to air pollution, a significant environmental issue. The purpose of this study is to provide a brief overview of the practical usage of SDA as a substitute material in the building sector, especially for soil stabilization. The article provides an overview of SDA use in the construction sector and examines development trends such as strength and durability. The findings indicate that implementing SDA into soi the soil stabilization sector benefits both sustainability and zero-waste technology. Environmental concerns about using SDA are also discussed, as are methods for minimizing the dangerous influence on the surrounding environment for future disaster risk reduction due to soil failure.
