The development of a country's infrastructure relies heavily on the use of cement concrete as the major building material. The aggregate represents a substantial amount of the total volume of concrete. However, the continuous exploitation of granite rock to obtain coarse aggregate adds to the growing demand for natural resources among future genera...

Cracks in structures pose significant risks to safety, integrity, and functionality, necessitating efficient and accurate analysis methods. This paper presents an innovative approach to crack analysis by integrating Artificial Intelligence (AI) techniques with Natural Language Processing (NLP) methodologies. Initially, NLP techniques are employed t...

The assessment of surface cracks in concrete structures plays a pivotal role in determining structural integrity. However, current diagnostic technologies suffer from drawbacks such as being time-consuming, subjective, and reliant on inspectors' experience, resulting in low detection accuracy. This paper seeks to address these issues by proposing a...

To develop a sustainable concrete solution, the aggregates and cement in the concrete mixture were partially replaced with Cocos nucifera endocarp (coconut shell) aggregate and biomass ash (sugarcane bagasse ash) respectively. The fresh and hardened properties were studied for three types of mixes (i) the concrete mix with 10-30% replacement of cem...

A r t i c l e h i s t o r y A B S T R A C T Regular clay bricks and concrete blocks are replaced with lightweight fibre-reinforced foam concrete modules. For light weight foam concrete, various natural and synthetic fibes are employed as micro-and macro-fibre reinforcement. Three distinct fibres were used as fibre reinforcement in this study, and t...

Confined concrete columns composed of core concrete and encasing tubes replaces most of the RCC columns in civil structures. To enhance the performance of such confined column, the outer confining steel is replaced with GFRP composites and further to enhance the performance of GFRP confined column with respect to load-carrying capacity, corrosion r...

In recent years, a new type of natural fibre known as fish tail palm fibre (FTPF) has been discovered, and several studies have been conducted to investigate the fibres physiochemical properties, strength attributes and therapeutic capabilities. Because the utilisation of these fibres in the concrete industry is limited, this research aims to emplo...

This research work focuses on the effect of natural caryota urens plant fiber as reinforcement on the strength properties of concrete of different grade. Fiber length of 10 mm, 20 mm and 30 mm were added to the concrete mix at an amount of 3% of the binder content. Three different lengths of fibers at fixed volume fraction were added to M30, M40 an...

polymer balls can supply water to the mortar or concrete mixture when added during the initial stage of mixing the concrete ingredients. It supplies the absorbed water during the hydration process of concrete as an internal water source. Water Absorption polymers (WAP) can absorb water up to hundred times of their own weight. Using this idea, the c...

To improve the pre-cracking behavior and post peak strength of concrete composites, a new variety of natural fiber called Fish Tail Palm Fibers was used as micro reinforcement in concrete. Fish Tail Palm Fibers (FTPF) are completely renewable natural resources and are available in abundance, in many parts of the country including India. Three diffe...

In this study a new variety of natural fiber called Caryota-Urens (CU) fiber also called as Fish Tail Palm Fiber (FTPF) was used as micro fiber reinforcement in Self-Compacting Concrete (SCC) and the fresh and mechanical properties were studied. Different volumes of fibers ranging from 1% - 5% of the weight of binders were used to study the effect...

Pervious concrete a sustainable solution with limited fines or no fines and interconnected voids, has many environmental benefits, such as reducing the stormwater runoff , improving the groundwater table, reducing water pollution, and mitigating urban heat island. Many research works have been done in Pervious Concrete (PC) by varying different par...

Concrete being the widely used material in construction work is strong in compression and brittle in nature. Addition of fibres to the cementitious mix helps to improve the tensile property of the material, particularly after reaching the yield load. In addition, fiber reinforced cement composites exhibit better toughness, crack resistance, flexura...

Este estudio presenta la investigación experimental llevada a cabo en una columna de hormigón de arcilla expandida confinada por tubo de acero perforado reforzado por láminas de polímero reforzado con fibra de vidrio (GFRP) bajo compresión uniaxial.
