Influence of Waste Concrete and Glass Recycled on the Strength Properties of Green Reactive Powder Concrete

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

Controlling Fresh Properties of Self-Compacting Concrete Containing Waste Glass Powder and its Influence on Strength and Permeability

Adjustment of superplasticizer (SP) dosage is one of the main factors in proportioning of self-compacting concrete (SCC) mixtures. The quantity of SP has to be within certain limits to avoid segregation or bleeding, which otherwise could alter the microstructure of concrete and affect its performance in the longer-term. Since SCC is produced with high cement content, some issues, such as high c...

Influence of Ultrafine 2CaO·SiO2 Powder on Hydration Properties of Reactive Powder Concrete

In this research, we assessed the influence of an ultrafine 2CaO·SiO₂ powder on the hydration properties of a reactive powder concrete system. The ultrafine powder was manufactured through chemical combustion method. The morphology of ultrafine powder and the development of hydration products in the cement paste prepared with ultrafine powder were investigated by scanning electron microscopy (S...
