Manufactured sand differs from natural sea and river dredged sand in its physical and
mineralogical properties. These can be both beneficial and detrimental to the fresh and …

The Middle East (ME) is characterized by its water shortage problem. This region with its arid
climate is expected to be the most vulnerable in the world to the potential impacts of climate …

The use of polymers in reinforcement is a field that is gradually gaining momentum in the
world of material science. The use of these polymers aids in reducing the menace of …

This paper validates Dewar's particle packing modelling (PPM) theory for implementing both
fine and coarse recycled concrete aggregates (RCAs) from using aggregates with multi-size …

The paper describes assessment of the performance of cement-poor concretes on the basis
of packing theory. The concretes are intended for sealing segments of deep boreholes and …

To obtain an efficient and economic concrete mix, determination of the optimum proportions
of binary aggregate mixtures of coarse and fine aggregates is necessary. This study was …

Fractured, very permeable rock hosting repositories for radioactive waste will require
grouting. New grout types of possible use where long-term performance is needed should …

Due to its convenience, speed, and quality of implementation, overusing of selfconsolidating
concrete necessitates adopting new methods to optimize its designs. This study focuses on …

La restauration des sites miniers peut se faire par plusieurs méthodes, entre autres à l'aide
