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 ...

Debris flow ensued as a result of tailings dam failure depends greatly on the fluidity of slurry created and is better described by measuring the rheological properties. In the present study, rheological properties (i.e. viscosity and yield stress) of bauxite residue are measured using dynamic shear rheometer with parallel plate configuration to un...

The aim of this research is to provide a quantitative method for evaluating concrete segregation. Because of various conditions of concrete materials, mix proportions, and delivery, concrete can be segregated. The acquisition inspection executed in construction field for supplied ready-mixed concrete is an important quality control process for conc...

High-strength concrete (HSC) is defined as concrete that meets a special combination of uniformity and performance requirements, which cannot be attained routinely via traditional constituents and normal mixing, placing, and curing procedures. It is a complex material since modeling its behavior is a difficult task. This paper intends to show the f...
This work aims to shape a hollow cylinder with a geopolymer and an additive manufacturing process (3D printing) without organic additives. The formulation of a geopolymer composite using only mineral parts is proposed and the parameters of the 3D printing process were optimized. The mechanical properties, the microstructure, and the adhesion of the...

The traditional interpretation of a legendary, though controversial, fourth century text of Ammianus Marcellinus is that an earthquake-generated tsunami hit Alexandria on 21 July 365. The causative earthquake is usually associated with the Aegean Arc, and it has been modeled through elastic dislocation of the up to 9 m uplift of Crete which occurre...

Concrete is expected to be placed right after the mixing of cement, aggregates, and water. However, an unexpected delay before placing can occur for many reasons. This affects the compressive strength of the hardened concrete. The aim of the study is to observe the effect of casting delay (up to 480 min or 8 h) on the 28-day compressive strength of...
This work aims at determining the influence of orientation and dimensions of structural samples on the measurement of their burning properties and therefore on the assessment of fire hazard. Poly (methylmethacrylate) (PMMA) slabs are tested thanks to a new experimental setup specially designed to study the combustion of large samples exposed to med...
We distinguish two types of mass-transport deposits (MTDs) within a salt-related slope minbasin. The locally-derived MTDs are sourced from growing structures bounding the minbasin, and the more extensive, regional, MTDs are sourced from the shelf of the continental margin, at least 100 km east of the study area. The two types of MTDs have different...
The combined effect of recycled tires and microspheres as substitutes of raw material to produce modified concrete as of raw materials used in the manufacture of traditional concrete was explored in this work. Traditional and mix concrete were designed and modified concrete mixes with 15% by mass of fine aggregate were replaced in a 0:1, 1:1, 1:3, ...
