RISImprovement of Shrinkage Reduction and Superplasticity of Polycarboxylate Admixture by Ester and Silane Groups
Publisher: ASCE
Abstract: Polycarboxylate ether (PCE) superplasticizers are widely used in concrete, but in some cases, PCE aggravates the occurrence of cracks. This study evaluates the shrinkage reduction and plasticizing properties of a newly ...
Production and Performance of Coal Gasification Slag–Based Denitrification Materials in Cement Kilns
Publisher: ASCE
Abstract: Nitrogen oxide emissions have attracted much attention due to their impact on the atmospheric environment and human health. Combined with NO removal in the cement production process, coal gasification slag was used to ...
Molecular Structural Characterization and Bond-Breakage Investigation of Calcium Silicate Hydrate Gel Intercalated by Ionized Surfactants Subjected to Uniaxial Tensile Deformation
Publisher: ASCE
Abstract: The wide application of surfactants in cement-based materials requires the understanding of the influence of surfactants on the structure and properties of C–S–H gel. In this study, cation surfactants (CTAB) and anion ...
