Introduction he present boom in the field of construction has caused the huge rise in the demand for Portland cement which is the important material in the production of concrete. It was noted by Ramos, Matos, & Sousa-Coutinho, [1] that globally more than one cubic meter of concrete is produced per person per year with Portland cement being the main component, but it produces the greatest environmental burden. Currently, about 3 billion tons of Portland cement are consumed worldwide and for the every 600 kg production of cement, a 400 kilograms of carbon dioxide (CO2) gas is released. In the recent years, raising concern about global environment and utilization of renewable energy resources leads to modify the traditional practices of energy production. Among these resources, wood waste is a promising source of renewable energy [2]. Wood biomasses namely sawdust is the significant waste produced from the wood industries. The utilization of wood-fuel for generating energy is the ultimate solution for problems connected to wood waste. However, the thermal combustion generally reduces the mass and the volume of the wood waste but it yields an inheritance problem that is formation wood ash (Sawdust ash). In the USA alone, about 3 million tons of wood ash are produced annually [3]. Usually, timber industries have its own small-scale boiler units which employ generated wood waste in the unit itself as fuel for heat energy production regarding other processes like drying the finished products. Moreover, it was detected that wood ash produced by timber manufacturing industries is not handled properly, which may cause serious environmental and health problems. Research has been conducted on SDA as a cement replacement material. Findings have indicated that SDA can effectively be used as cement replacement material in the concrete of adequate strength and durability performances. In long term, the utilization of SDA as replacement of cement is expected to carry substantial decrease in the cost of construction since cement is the most expensive integral part of the concrete. 2. Previous Research The summary of literature review has been presented in Table 1. It indicates the previous findings on the utilization of SDA as replacement of cement in the concrete. It was explored by the researchers that the sawdust ash has great potential to perform as a Pozzolanic material, it can be considered for the normal and high strength concrete as a cement replacement. Through the adoption of these practices can reduce the environmental burden and creates a solution to the sustainable construction material to build cost-effective structures. T Abstract: Cement is the main materials for the construction and it is very expensive. Considering the growing demand of cement, the researchers are probing towards the new cement replacement materials. To achieve the sustainable development, it is imperative to use supplementary cementing materials in the field of concrete engineering. Currently, numerous research has been conducted on the utilization of sawdust ash as a cement replacement in the production of green building material and an alternative means of wood waste minimization. The result of this research work has indicated that sawdust ash has a good potential to be utilized as replacement of ordinary Portland cement for the production of concrete. The aim of this review work is to summarize previous research studies on utilization of sawdust ash as a cement replacement. Hence, this review paper will provide the significant idea and valuable information for the fellow researchers working for the composite cement materials, supplementary cementing materials in the field of concrete technology and it is the considerable verdict that more research is deserved to be carried out on the development of high-strength concrete incorporating sawdust ash as a cement replacement.
