Copper slag (CPS) is a large amount of waste material produced during the manufacture of copper. The disposal of this waste material becomes a problem for environmental concerns. Therefore, it is necessary to explore feasible alternate disposal options.
Microsilica was incorporated in a constant quantity of 30 kg/m3 in all mixtures, which is equal to 6.4%. The main objective of the current work is to confirm the possibility of producing high-strength and durable SCC by incorporating a high percentage of SCMs as a partial replacement for ...

St Paul’s Cathedral was London’s tallest building for 250 years. With treasonous relish, this crown was seized in 1961 by the Empress State Building, a dumpy pile of concrete and glass, ignored by all but those unlucky enough to work near it. That decade saw architec 修造,当艾萨克・...
Based on a study of the mechanical properties of bridge deck leveling concrete (BDLC) containing different mud powders at various ages, the effects of mud powders on concrete durability were evaluated through rapid chloride permeability testing, freeze–thaw testing, and the coupling of salt ...
Concrete is one of the world’s largest industries [1], with global use of approximately 25 gigatons per year [2]. Concrete has a very high negative impact on the environment, caused by the emission of CO2 and exploitation of natural resources, due to its huge volume of use [3]. More...
