Investigation of the possibility of the reutilization of some industrial wastes [PDF]

Journal of the Serbian Chemical Society, 2005
The utilization of nitrogypsum and bottom ash, wastes from the factory “Milan Blagojevic” (Lucani–Serbia), was investigated. For this purpose, mixtures composed of calcined nitrogypsum (CaSO4·0.5H2O), ash (mass ratio 1:1) and water (water/solid mass ...

Water-to-cement ratio influence on low-carbon cements performances [PDF]

, 2019
Portland Cement (PC) is the most important active ingredient in most of the construction concrete. However, the PC production is associated with a high carbon dioxide release (around 1 ton of CO2 per ton of PC).

Long-term behavior of mortars experiencing delayed ettringite formation

Cement
Ettringite formation is an expansive reaction that causes cracking in the hydrated cementitious materials. This research has investigated the mechanisms of ettringite formation by examining the chemical and physical structure of the reactants and ...

Reduction of Concrete Deterioration by Ettringite Using Crystal Growth Inhibition Techniques: Part II Field Evaluation of Inhibitor Effectiveness, TR-469, 2004 [PDF]

, 2004
The effects of diethylenetriaminpenta(methylenephosphonic acid) (DTPMP), a phosphonate inhibitor, on the growth of delayed ettringite have been evaluated using concrete in highway US 20 near Williams, Iowa, and the cores of six highways subject to ...

Potential reduction of concrete deterioration through controlled DEF in hydrated concrete [PDF]

, 2013
Delayed ettringite formation (DEF) is a chemical reaction with proven damaging effects on hydrated concrete. Ettringite crystals can cause cracks and their widening due to pressure on cracked walls caused by the positive volume difference in the reaction.

Effect of Calcium Aluminate and Carbide Slag on Mechanical Property and Hydration Mechanism of Supersulfated Cement

Buildings
Supersulfated cement (SSC), a low-carbon, energy-efficient, eco-friendly cementitious material, is mainly made from industrial byproducts. However, SSC’s slow early strength development leads to inadequate initial hardening and reduced durability, which ...
