Words representing concrete concepts are processed more quickly and efficiently than words representing abstract concepts. Concreteness effects have also been observed in studies using event-related brain potentials (ERPs). The aim of this study was to examine concrete and abstract words using both reaction time (RT) and ERP measurements to determine (1) at what point in the stream of cognitive...

This paper presents and evaluates a new method for producing Slurry Infiltrated Fiber Concrete (SIFCON). A study was carried out to investigate the impact on mechanical properties of SIFCON, where several cubes, cylinders, prisms were cast compare proposed gradual traditional multi-layer using same mixing proportions: 6% straight steel fiber, cement, sand, 10% silica fume replacement, 2.4% supe...

Self – compacting concrete (SCC) is a high – performance concrete that can flow under its own weight to completely fill the form work and self-consolidate without any mechanical vibration. Such concrete an accelerate the placement, reduce the labor requirements needed for consolidation, finishing and eliminate environmental pollution. Oyster shell were collected from river and sea & it produced...
