A Review on Strength and Durability Properties of Wooden Ash Based Concrete

The partial replacement of cement in concrete with other building materials has come to light because of research on industrial waste and sustainable building practices. Concrete is made more affordable by using such components, and it also helps to ease disposal worries. Ash made by burning wood and other wood products is one example of such a substance. Many researchers focused on the utilization of wooden ash (WA) as a construction material. However, information is scattered, and no one can easily judge the impact of WA on concrete properties which restrict its use. Therefore, a details review is required which collect the past and current progress on WA as a construction material. relevant information. This review aims to collect all the relevant information including the general back of WA, physical and chemical aspects of WA, the impact of WA on concrete fresh properties, strength properties, and durability aspects in addition to microstructure analysis. The results indicate the WA decreased the slump and increased the setting time. Strength and durability properties improved with the substitution of WA due to pozzolanic reaction and micro-filling effects. However, the optimum dose is important. Different research recommends different optimum doses depending on source mix design etc. However, the majority of researcher suggests a 10% optimum substitution of WA. The review also concludes that, although WA has the potential to be used as a concrete ingredient but less researchers focused on WA as compared to other waste materials such as fly ash and silica fume etc.

Automated summary

The partial replacement of cement with other building materials in concrete has gained attention due to research on industrial waste and sustainable construction practices. Wooden ash is one such substance that can be utilized in construction. However, there is a lack of comprehensive information on the impact of wooden ash on concrete properties. This review aims to gather relevant information on the background, physical and chemical aspects, and the effects of wooden ash on concrete properties. The results show that wooden ash can improve the strength and durability of concrete, but the optimal dosage is important. It is recommended that a 10% substitution of wooden ash is ideal. However, research on wooden ash in comparison to other waste materials is relatively limited.
