In this work, a micromechanical model is used in order to predict the failure surface of cement concrete subject to multi-axial compression. In the adopted model, the concrete material is schematised as a composite with the following…
To investigate the mixing amount of graphene oxide and water cement ratio on the microstructure and mechanical properties of graphene oxide reinforced cement based composite material, graphene oxide suspension was developed using improved…
The creation of cracks, which are the most common cause of structural failure, has a significant impact on the structure's strength and durability. As a result, effective repair and maintenance are vital and unavoidable for treating any of…
Two experimental techniques are used study the response of cement mortar beams subjected to three-point bending under various loading protocols. The techniques used are the detection of weak electric current emissions known as Pressure…
An experimental and numerical study was achieved to investigate the behavior of masonry beams internally reinforced using carbon fiber-reinforced polymer (CFRP) and hybrid steel/CFRP reinforcements. In addition, the use of masonry…
Bendable concrete is also defined as engineered cementitious composites because of its great ductility and tight fracture width limitation. ECC mixtures by adding additional Portland cement, silica sand and fly ash, fiber types…
Simulating the concrete fracture unlike other elastic and brittle materials quite different due to its quasibrittleness. The present research focussed on assess softening behavior by varying different fractions of aggregates and cement…
The reuse of concrete waste as a secondary aggregate could be an efficient solution for sustainable development and long-term environmental protection. However, the variable quality of waste concrete, especially with various compressive…
The main goal of this work is the formulation of a self-compacting repair mortars (SCRMs) containing limestone dust (LD) and natural pozzolan (NP). For this purpose, a control mortar (SCRM-0) and two different mortars types, one with 10%…
The dynamic mechanical property of concrete is very complex and is one of the hot spots in academic research. In this paper, concrete is considered as a three-phase composite composed of cement mortar matrix, coarse aggregate and…
