Steel slag is a calcium-rich but hydration-inactive material. Accelerated carbonation is an effective method to activate its reactivity. In this study, a kind of widely available steel slag, basic oxygen furnace slag (BOFS), was used as the sole material for fabricating dry-mixed compacts; the interactions of casting pressure, water to solid (w/s) ...

Electrokinetic desalination is very useful method for the removal of salt ions from porous building materials. This study investigates the influence of electric potential, electric current and pH distribution on the electrokinetic desalination of sodium chloride contaminated specimens of fired clay brick and sandstone. The measurements show that th...

The fatigue behavior of a reinforced UHPFRC (Ultra High Performance Fiber Reinforced Cementitious composite) T-shaped beam under four-point bending is investigated. The beam was subjected to a fatigue loading range equal to 49% of the static resistance and failed after 0.88 million cycles. It was instrumented with extensometers, strain gauges and d...

This investigation employed an interrupted torsion fatigue test using the linear amplitude sweep procedure to assess the intrinsic self-healing potential of unaged, aged, rejuvenated, and re-aged asphalt binders. Continuous oscillatory shear strain loading at different damage levels were interrupted with a single rest period of different durations....

Bitumen is a crucial building material in road construction, which is exposed to continuously higher stresses due to higher traffic loads and changing climatic conditions. Therefore, various additives are increasingly being added to the bitumen complicating the characterisation of the bituminous binder, especially concerning the reuse of reclaimed ...

A basic investigation into whether a geopolymer can be utilized as a part of an artificial barrier during radioactive waste disposal was conducted in this study. Geopolymers are comprised primarily alumina and silica, and they exhibit negligible leaching owing to the absence of calcium. Studies on geopolymers are limited compared to those on other ...

Water treatment plants generate sludge, which is mainly composed of inorganic minerals and a reduced fraction of organic matter. Even though the water treatment sludge (WTS) can be classified as non-inert and non-hazardous waste, there exists a clear interest in its potential valorization and reuse in other industrial sectors. This study presents t...
