Abstract: The possibility of improving some properties of precast concrete tiles under static load has been studied in this research. The experimental approach was adopted in this research to investigate the effect of two types of wire mesh reinforcements on some properties of precast concrete tiles especially flexural failure load. The experimenta...

The objective of this paper is to inspect the effect of changing the density of the impressed current and wetting-drying condition on accelerated corrosion of reinforced concrete specimens by a galvanostatic method. Small-scale reinforced concrete columns were prepared and then artificially corroded by different setups of accelerated corrosion unde...

In this research, the effect of using crushed brick as an alternative to the coarse aggregate on some load-bearing hollow concrete block properties were investigated. The hollow concrete blocks with standard dimension (150 ×150×300) mm, were produced. The mix proportions were (1) cement to (6) total aggregate. The course aggregate was replaced by t...

The aim of this study is to investigate the influence of the concrete age on the measurement of the nondestructive tests. This study involves two types of the Investigational work; first type deals with field investigation on existing concrete, which the effect of concrete age on measurements of two types of nondestructive, rebound hammer and ultra...

Assessment of in-situ concrete strength by means of cores cut from hardened concrete is accepted as the most common in-situ nondestructive method, however the assessing of the concrete in the existing buildings, particularly in the troubleshooting of problems with new construction, If the strength of standard compression test specimens found to be...

There are large deposits of waste materials from various industrial or building activity all over the world. Out of this enormous quantity of waste, a little amount gets recycled, while the rest is dumped in vulnerable places. This paper examines the potential use of waste materials in subbase, including recycled chips derived from waste polyethyle...

Reactive Powder Concrete (RPC) is a combined material that will allow the concrete industry to enhance material consumption, produce economic benefits, be more durable, and be more environmentally friendly. Due to the highly dense microstructure of RPC, it performs poorly at high temperatures due to the formation of high pore pressure, which causes...

Plastic waste is accumulating with the progression of time, posing significant difficulty around the world. As a result, effective solutions to environmental concerns are required. There is also another issue, which is that projects frequently encounter weak soil, which must be modified. The purpose of this paper is to conduct a comprehensive study...

This paper introduces the outcomes of experimental and analytical investigation on the effectiveness of Carbon Fiber Reinforced Polymer (CFRP) wrapping for retrofitting of the corrosion affected reinforced circular concrete columns. Small scale reinforced concrete columns were cast, cured, artificially corroded at different levels up to 30 %, repai...

Corrosion is a major cause of deterioration and cracking in reinforced concrete (RC) members and leads to a significant reduction in their structural capacity and service life. The rehabilitation of damaged RC members using carbon fibre-reinforced polymer (CFRP) is a viable and cost-effective method. This study evaluates the effectiveness of CFRP w...

Plastic materials can now be intelligently and creatively utilised in civil engineering applications such as the creation of soil improvement materials to accomplish economic goals while diminishing the environmental impact of plastic waste. In this study, the influence of adding recycled polyethylene terephthalate granules (PET)) to the strength p...

Across the world, a huge amount of waste materials is deposited from different industrial or construction activities. Out of this massive waste quantity, a petite is recycled and remaining is dumped in vulnerable lands. This paper deals with the potential utilization of solid waste in reactive powder concrete, practically powdered glass originating...

Nowadays, plastics materials can be smartly and alternatively utilized in the civil engineering application such as soil improvement material to accomplish economy and diminish the environmental impact of the plastics waste. In the current study, the influence of adding recycled Polyethylene terephthalate granules (PET)) on some strength properties...

Corrosion of reinforcement has been identified as the deterioration mechanism of reinforced concrete structures, which seriously affects the safety and integrity of structures. The corrosion of the embedded reinforcing steel in concrete is a major problem facing civil engineers today, which initiates 80% of the reinforced concrete structures deteri...

Fire is reflected as one of the most serious possible risks for buildings and constructions. The main objective of this research is to investigate the effect on the performance of beams reinforced concrete under and without fire conditions by adding waste polypropylene fibers (WPPF) with two variable values of volume fraction. Six beams with differ...

A great number of the reinforced concrete structures in corrosive environments like marine structures have suffered excessive deterioration. Most concrete structures, such as concrete piles and columns in highways bridges, that have been constructed in recent decades also show signs of deterioration owing to the corrosion of reinforcing steel. This...

Present study aims to observe the consequence of varying the intensity of the accelerating impressed electrical current and situations of wetting-drying as hybrid accelerated corrosion regime on synthetically corroded concrete specimens, especially the loss of steel mass. Small-scaled reinforced concrete columns were fabricated and synthetically co...

Lightweight concrete mentions to any concrete produced to an oven-dry density less than 2000 kg/m3. This can reached by replacement of natural aggregates with lightweight aggregate, no fine aggregate and or adding foamed agent to the concrete. This research usage of recycled paper as an aggregate replacement in producing a lightweight concrete for...

Reactive Powder Concrete (RPC) is the most commonly used type, known as Ultra High-Performance Concrete (UHPC). This type of concrete requires very low water/binder ratios to ensure that the microstructure is very dense and impermeable. Thus, it also needs special types of curing to ensure its high strength, high durability, and dimensional stabili...

A polyethylene terephthalate plastic material is widely used in Iraq for packages manufacturing, especially for the mineral water bottles. They turn out to be waste very rapidly due to their particular short period of use. Furthermore, the recycling amount of polyethylene terephthalate bottles is considerably fewer than the sales of virgin polyethy...
