Effect of Dispersed Reinforcement on Ultrasonic Pulse Velocity in Stabilized Soil. [PDF]
Materials (Basel), 2021 One of the fundamental techniques for road subgrades is soil stabilization. Considering the high emission of carbon dioxide during the production of binders, novel techniques to reduce the binder are being studied. Thus, we investigated dispersed reinforcement in stabilized soils. A study was conducted to determine the ultrasonic pulse velocity in nine

Factors influencing ultrasonic pulse velocity in concrete [PDF]
Revista IBRACON de Estruturas e Materiais, 2020 Abstract The hydration process of Portland cement triggers reactions of stabilization of minerals from the contact of the clinker with water, which is the Hydrated Calcium Silicate (C-S-H), the Etringite (3CaO.Al2O3.3CaSO4.32H2O) and the Portlandite (Ca(OH)2). In order to understand the effects of the evolution of hydration in cement, it is possible to
