Factors influence the reaction degree of slag in slag blended cement

The hydration kinetics of slag is generally divided into three stages: (1) a nucleation period during which product growth is accelerating, (2) a phase boundary controlled stage, and (3) a diffusion controlled stage.

The reaction degree of slag in blended cement is influenced by many factors. The m......

The activation theory of slag in blended cement

As it is well-known, the activation of latent slag in blended cement is implemented by calcium hydroxide (CH, Ca(OH)2) which is the main cause maintaining the high pH value of pore solution.

The activation happens as the break of glass layer of slag particles. However, how does the break take place......

Features of microstructure development in the inner product of reacting slag in blended cement

The morphology of inner product region derived from alite or belite is identical to those present in neat OPC paste. In mature pastes, fully hydrated small grains of both alite and GGBFS often display a coarse morphology.

Generally, inner product in larger grains has a dense homogeneous morphology ......
