Moisture diffusion in cement pastes with hydrophobic agent

Hao Zhang et al.

Summary: This paper analyzes the influence of carboxylic acid ammonium salt on the hydrophobicity of cement-based materials and investigates its effects on hydrophobicity, moisture diffusion, and hydration products through experimental methods. The results show that the addition of carboxylic acid ammonium salt increases pore volume, and proposes an analytical hydrodynamic model to analyze the relationship between pore characteristic parameters and cementitious materials permeability.

Effects of synthetic CSH-tartaric acid nanocomposites on the properties of ordinary Portland cement

Haiyan Li et al.

Summary: In this study, tartaric acid was used as a stabilizer to prepare nano CSH, and its effect on the hydration and hardening of ordinary Portland cement was investigated. The results showed that tartaric acid intercalated the interlayer regions of CSH, and its release from the nanocomposites adjusted the pore structure and enhanced the compressive strength of cement.

A review on recent advances in the fabrication and evaluation of superhydrophobic concrete

Yuanlong Wu et al.

Summary: Water penetration can lead to severe deterioration and failure of concrete structures, but superhydrophobic concrete materials have gained considerable attention for their unique waterproofing properties. This review examines the strategies for constructing superhydrophobic concrete, discusses the impact on mechanical properties, and reviews the evaluation criteria for durability performance. The remaining challenges in fabrication and application of high-performance superhydrophobic concrete are also addressed.

Modification of water absorption and pore structure of high-volume fly ash cement pastes by incorporating nanosilica

Qian Huang et al.

Summary: The study found that the addition of nanosilica increased the compressive strength and reduced the water absorption of HVFAC pastes. Nanosilica could react with Portlandite to produce additional C-S-H gel, leading to the hydration of a higher content of fly ash.

Silica fume/capric acid-stearic acid PCM included-cementitious composite for thermal controlling of buildings: Thermal energy storage and mechanical properties

Gokhan Hekimoglu et al.

Summary: In this study, a novel kind of cement mortar was produced with thermal energy storing/releasing properties by incorporating CA-SA eutectic PCM and SF to form FSC-PCM. The FSC-PCM showed great stability in terms of thermal properties, chemical structure, and cycling reliability. Replacement of OCM with FSC-PCM in different weight fractions resulted in improved thermoregulation performance in indoor environments, demonstrating potential for energy savings in buildings.

Rational application of nano-SiO2 in cement paste incorporated with silane: Counterbalancing and synergistic effects

Jingxian Yang et al.

Summary: The study found that nano-silica can counterbalance the retarding effect of silane on cement hydration and early strength development, and the dispersing effect of silane on nano-silica has a positive impact on the flowability of cement paste; the synergistic enhancement effects of nano-silica and silane on water resistance of cement paste result in remarkable 3D superhydrophobic behavior and lower water absorption rate.

Study on alkylsilane-incorporated cement composites: Hydration mechanism and mechanical properties effects

Mingjun Xie et al.

Summary: The length of alkyl chain in silanes affects the hydration process and mechanical properties of cement, with shorter chain resulting in stronger retardation of hydration. Changes in porosity due to silane incorporation may also contribute to the decrease in mechanical properties. Additionally, SEM images reveal the formation of fiber-like needle products on the surface of hydrated cement, which are likely composed of specific types of silanes produced from the reaction between calcium hydroxide and silane.
