Concrete is the most generally used construction material in buildings,pavements, and infrastructures. Concrete is a construction materialcomposed of cement as binder, fine aggregates and coarse aggregatesmixed with water which hardens with time. Concrete is a versatileconstruction material within the housing industry of the planet. Thestandard of ...

The main reason causing the degeneration of steel reinforced concrete supposed to be corrosion of reinforcement steel. In this study, compressive strength, weight loss and field emission scanning electron microscopy (FESEM) were performed in order to investigate about the changes due to addition of 2% bio-friendly and chemical inhibitors per cement...

The main reason causing the degeneration of steel-reinforced concrete is supposed to be corrosion of reinforcement steel. In this study, electrochemical impedance spectroscopy (EIS), linear polarization resistance (LPR), and weight loss have been utilized to evaluate the corrosion of steel reinforcement in contaminated, chemical inhibitor (sodium n...

Foundry sand (FS) waste creates a serious solid waste management problem worldwide due to the high volumes produced, necessitating alternatives to landfilling. A possible route is its use in concrete; however, the current consensus is that FS can only be used for modest sand replacements, based mostly on evidence on concrete with clay-bound FS (gre...

This research focused on investigating the effects of recycled aggregates on the material properties of concrete and the structural performance of reinforced concrete beams. Two different sources of recycled aggregates, crushed red bricks and demolished concrete, collected from local construction and demolition wastes, were analysed. The pre-wettin...
This chapter is dedicated to several kinds of natural pozzolans that occur around the globe and describes their specific characteristics, origin and use in concrete. Moreover, the advantages and disadvantages of their use in concrete mixes are highlighted in terms of concrete properties. In particular, the referenced properties in this chapter are ...

The evaluation of early age properties of concrete is critical for ensuring construction quality. This paper presents a sensing method to use ultrasonic guided waves in a rebar for monitoring the early age properties of cementitious material. An EMAT sensor was used to excite the longitudinal mode L(0,1) wave in a rebar embedded in cement/mortar, a...

The objective of this research was to examine the technical feasibility of upgraded bottom ash from municipal solid waste incinerators as fine and coarse aggregate in concrete. The effect of partial replacement of natural sand and gravel by such bottom ash on all relevant properties of concrete (technological, structural as well as durability and r...
