RISEffect of Multiwalled Carbon Nanotube Functionalization with 3-Aminopropyltriethoxysilane on the Rheology and Early-Age Hydration of Portland Cement Pastes
Publisher: ASCE
Abstract: The mechanical performance of cementitious materials can be improved by incorporating carbon nanotubes (CNTs). Nevertheless, some challenges must be overcome, such as reducing the agglomeration trend of CNTs and minimizing ...
Fresh Properties of Low-Carbon Cement Pastes Incorporating Industrial By-Products
Publisher: American Society of Civil Engineers
Abstract: Cement production involves limestone decarbonation and fuel consumption, making it responsible for almost 10% of worldwide CO2 emissions that worsen the effects related to global warming. Consequently, finding alternative ...
Natural and Accelerated Carbonation in Concrete Associated with Recycled Coarse Aggregate Treated by Air Jigging Technology
Publisher: ASCE
Abstract: Recycled coarse aggregates (RCAs) are widely used as a sustainable material in the construction sector. However, the variability of the material is the main factor that limits its use in practice. This paper investigates ...
Influence of Nanosilica and Superplasticizer Incorporation on the Hydration, Strength, and Microstructure of Calcium Sulfoaluminate Cement Pastes
Publisher: American Society of Civil Engineers
Abstract: This study investigated the effect of incorporating three types of nanosilica (NS), two powders, and one colloidal suspension on the hydration, strength, and microstructure of calcium sulfoaluminate (CSA) cement pastes ...
