The interfacial transition zone (ITZ) has a significant negative impact on the structural performance of concrete. This can be ameliorated by introducing mineral additions into In this study, different forms (degree circularity) coarse aggregates and three contents (10 %, 15 % 20 %) addition (natural pozzolan) were used to prepare ordinary article aims determine optimal effective mixture (the b...

Sulfur cements have drawn significant attention as binders because sulfur is a byproduct of fossil fuel refining. that can be formed by the vulcanization elemental and plant-derived olefins such terpenoids are particularly promising from sustainability standpoint. A range terpenoid–sulfur shown compressional flexural properties exceeding those some commercial structural mineral cements. Pozzola...

The cementitious materials under consideration by Caltrans for rigid pavement construction may be classified into four categories: Portland cements and blends, calcium aluminate cements and blends, calcium sulfoaluminate cements, and fly ash-based cements. With the exception of Portland cements, most of the cementitious materials under consideration have not been extensively used for pavement c...

Roller Compacted Concrete (RCC), is a concrete with zero slump, which is used in damming and road pavement. Roller Compacted Concrete Pavement (RCCP) bear heavy traffic loads and severe weather conditions. This type of concrete is due to its economic and environmental capabilities, including reduced construction and maintenance costs, longer durability and longer lifetime, as well as environmen...
