The effects of thermoactivated recycled concrete cement (TARC) on mortar as a partial replacement for was examined. TARC is derived from waste through series processes. Different mixtures were tested, ranging 0% to 50% in 10% increments. A comprehensive range tests conducted assess the properties mortar, including fresh, mechanical, microstructure, and durability evaluations. fresh test indicat...

One of the growing demands in concrete manufacture is availability natural fine aggregates, which account for 35% to 45% total concrete. An alternative method disposal recycled aggregates (FRCA) generated from demolition and construction waste (C&DW) their usage mortar development mortar. The main aim this research work evaluate viability incorporating FRCA urban C&DW cement-based morta...

At present, many of the historic masonry structures in the most important seismic zone of Argentina present damages due to the actions to which they have been subjected. Therefore, it is necessary to study the behavior of walls of ceramic masonry of great thickness. This work presents the comparison between the results obtained from the numerical simulation of ceramic masonry walls subjected to...

Abstract Cement production is held responsible of polluting the atmosphere with carbon dioxide (CO 2 ). The researchers have shown that manufacturing one ton cement releases about half into atmosphere. So, there a need to produce alternative instead ordinary Portland (OPC). Waste materials such as sugarcane bagasse are difficult dispose which result in environmental hazard. This study investiga...

Due to their remarkable mechanical properties, multiwall carbon nanotubes (MWCNTs) are considered by many researchers to be a highly promising filler and reinforcement agent for enhanced performance cementitious materials. Currently, however, achieving an effective dispersion of MWCNTs remains a major challenge in developing high performance nano-cementitious composites, since carbon nanotubes ...

Early-age cracking continues to be a significant problem for new concrete construction. Two of the major contributors to such cracking are the heat released by cement hydration during the first few days of curing and the autogenous shrinkage that often occurs during the same timeframe. In this paper, three potential alternatives for reducing these contributions by modifying the concrete mixture...
