  A review on seawater sea-sand concrete: Mixture proportion, hydration ...

  202189 · Extensive studies have been conducted on seawater sea-sand concrete (SSSC) in recent years due to the shortage of freshwater and river-sand in many coastal areas. This paper reviews the properties of seawater and sea-sand and their effects on hydration, microstructure and properties of concrete. The relationship between mixture …

  Three-dimensional computer modeling of slag cement hydration

  2007729 · A newly developed version of a three-dimensional computer model for simulating the hydration and microstructure development of slag cement pastes is presented in this study. It is based on a 3-D computer model for Portland cement hydration (CEMHYD3D) which was originally developed at NIST, taken over in the authors’ group …

  Early-Age Cement Hydration Reactions

  Concrete gains desirable mechanical properties principally as a result of the hydration of the cement present. However, if pozzolanic or latent hydraulic admixtures are present, addi tional hydration reactions will contribute to strength devel opment.

  Hydration Reaction and Strength Development of Lunar …

  Low hydration reaction means low compressive strength, so slow setting mix proportion does not develop enough compressive strength at all. On the other hands, Rapid setting cement yield quick hydration reaction causing small pore concrete.

  Materials | Free Full-Text | Preparation of Butyl Acrylate …

  202345 · Due to its large volume and poor thermal conductivity, mass concrete is prone to temperature cracking caused by heat release during cement hydration after pouring. To address the issue of temperature cracking in mass concrete, this study utilized emulsion polymerization to prepare polybutyl acrylate (PBA) emulsions. At an optimal …
