The production of cement results in emission of many green house gases in atmosphere, which are responsible for global warming. Hence, the researchers are currently focused on use of waste material having cementing properties, which can be added in concrete as partial replacement of cement, without compromising on its strength and durability, which will result in decrease of cement production t...

Abstract—In this study, the Compressive strength of concretes made with Ground Granulated Blast furnace Slag (GGBS), Pulverised Fuel Ash (PFA), Rice Husk Ash (RHA) and Waste Glass Powder (WGP) after they were exposed 780C (exposure duration of around 60 minutes) and then allowed to cool down gradually in the furnace for about 280 minutes at water binder ratio of 0.50 was investigated. GGBS, PFA...

This paper studies the influence of assembly unit expansive agents (CaO and calcium sulphoaluminate) on limited free compressive strengths, expansion rate, carbonation resistance, chloride ion penetration resistance corrosion reinforcement concrete. The dosages agent were 0%, 3%, 6%, 9%, 12% by total amount cementitious materials. Two kinds mineral admixture (blast furnace slag fly ash) applied...

Approximately 10 % of CO2 is emitted from an ordinary Portland cement production. In and concrete production, emissions can be greatly reduced by using Supplementary Cementitious Materials (SCMs). addition, the microstructure durability properties are improved when silica-rich SCMs used. this study, Eco-Friendly design was carried out three different SCMs. Diatomite, ground granulated blast fur...

This paper investigates on the mechanical characteristics (compressibility and shear strength) of fly ash/ground-granulated blast-furnace slag (GGBS) mixtures at various mix ratios using consolidation direct tests, respectively. The studies were done a reduced duration load increment. compressibility behaviour has been found to improve with increase in GGBS content. Direct test results showed a...
