Magnetized water

Gerardo Araya-Letelier

Workability performance, strength performance, fracture performance, durability performance? . Please, tell us what performance in particular.

Chitaranjan Pany

-low water / binder ratio from strength point of view.

-adequate workability for field applications.

-concrete rheology is essentially governed by physical and chemical factors.

-optimisation of cementitious materials and the grain size distribution for improving strength and workability.

-low porosity

Adeyemi Adesina

Water to binder ratio for strength performance, and use of admixture for durability performance
