Prediction of Efficiency Factor of Natural Pozzolan by the Use of an Artificial Neural Network

, 2014
Because of the abundance of the mineral additives and the great variations on their physical and chemical characteristics, the development of a general concept for their use out of concrete is required. In this study, the concept of the efficiency factor

Activated Bentonite for Physical, Mechanical, and Durability Properties of Concrete—A Review

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.
Bentonite mostly exists in many counties and studies reported employment of activated bentonite in the concrete improves concrete performance more than using raw bentonite. However, it is not well‐known which range of bentonite activation temperature and employment dose gives the best concrete performance for the sustainability of activated bentonite ...

Impact on flow characteristics of concrete produced with artificial sand and many pozzolanic materials

Discover Civil Engineering
Abstract Overuse of cement and natural sand has damaging impacts on the environment and society. To solve this, manufactured sand can be used in place of natural sand and cement, together with pozzolanic materials—industrial waste byproducts such as metakaolin, GGBFS, silica fume, and fly ash.
