Concrete production has increasingly used seawater to overcome the challenge of freshwater scarcity. Although the use of seawater in concrete still has a controversial reputation, it is a promising application, particularly when combined with mineral admixtures such as natural zeolitic tuffs (ZT). This paper aims to investigate the effect of using...

This paper presents a finite element (FE) model of reinforced concrete two-way slab strengthened using fiber-reinforced polymer (FRP) sheets. This model was validated against experimental data from the literature and it showed acceptable prediction accuracy. Although carbon-FRP (CFRP) is the most commonly used composite in repairing and strengtheni...

Documentation of the historical sites is tremendously significant for managing and preserving them from human-made activities and natural disasters, as well as being a base for further analysis and development decisions. This study has introduced a procedure employing Geographic Information System GIS and Laser scanning techniques aiming mainly to...

1. Abstract This work investigates the toughening mechanisms in concrete due to fibre reinforcement when a crack propagates in a notched ultra high performance fibre reinforced concrete (UHPFRC). The specimen was imaged using X-ray computed tomography (XCT) during the in-situ loading. A wedge splitting test of a 40x20x25mm specimen was carried out...

Numerous scientists have studied basalt fiber (BF) reinforced concrete and found encouraging results. However, information is scattered, and compressive assessment is yet necessary to collect the data from prior research on BF, present research advancement, and future research guidelines of BF reinforced concrete. Furthermore, mostly research focus...

The distribution of stresses in laminated composite plates with an ellipse hole and having various stacking sequences, different geometric dimensions and subjected to in-plane axial tensile loading is studied and solved by FEM using ANSYS. The ANSYS computer program was applied using the finite element method to study Graphite/Epoxy Composite mater...

This research aims at studying the consistency of colored concrete that is stained using local materials as pigments available in Jordan. Since the colored concrete has its role in the architectural applications, it is important to produce colored mix that is workable as well as consistence. Colored concrete is used in different applications nowada...

A two-scale analytical-numerical homogenisation approach is developed to predict effective elastic properties of ultra high performance fibre reinforced concrete considering distribution of pore sizes acquired from 3D micro X-ray computed tomography (μXCT) images of 24.8μm resolution. In the first scale, the mortar, consisting of sand, cement paste...

Micro-scale X-ray computed tomography images of UHPFRC are used to construct finite element models for prediction of elastic properties using a two-step homogenization approach. In the first step, the mortar matrix with a large number of small voids is homogenized, and in the second the fewer large voids and steel fibres are modelled with the homog...
