Effects of Aggregate Gradation on Water Permeability

Concrete permeability is one of the key properties of concrete which largely effects concrete durability. Conventionally concrete permeability is considered as a function of water to cementitious materials ratio. But aggregate being the major constituent of concrete, was found to have considerable effects on various properties of concrete. In this research the effects of aggregate gradation on ...

Cement Replacement Material - an overview

Concrete is an artificial stone manufactured by mixing together coarse and fine aggregates, cement, water and often other components such as cement replacement materials, e.g., pulverised fuel ash, and chemical admixtures, e.g., superplasticisers. The grading of an aggregate defines the proportions of particles of different size in the aggregate.
