The February 2007 report issued by the International Panel on Climate Change (IPCC) has started in no uncertain terms that global warming is no longer an issue that has to be debated. According to the report, global warming is here, and drastic actions are needed for the long term sustainable of our environment. In these contexts that this paper discusses the role of supplementary cementing materials as partial replacement for cement in concrete in reducing green house gas emissions. In the new millennium, concrete incorporating self-curing agents will represent a new trend in the concrete construction. Curing of concrete plays a major role in developing the concrete microstructure and pore structure, and hence improves its durability and performance. Due to the high alkalinity of concrete it has always been susceptible to acid attack. Hence, in this investigation an attempt was made in order to know the behavior of Concrete specimens curing with acids such as HCL, Alkaline such as NaOH and sulphate solution MgSO4 and Na2SO4.
In the last decade the use of Supplementary Cementing Materials (SCMs) has become an integral part of high strength and high performance concrete mix design. The addition of SCM to concrete reduces the heat of hydration and extends the service life in structures by improving both long term durability and strength. Some of the commonly used SCMs are Flyash, Silica fume and Metakaoline. This paper presents results of the durability characteristic properties of M30 grade of Concrete with and without SCMs and Superplasticizers.
