Fresh concrete is that stage of concrete in which concrete can be moulded and it is in plastic state. This is also called "Green Concrete". Another term used to describe the state of fresh concrete is consistence which is the ease with which concrete will flow. The transition process of changing of concrete from plastic state to hardened state.

The Mechanical Properties of Alkali-Activated Slag-Silica
Jun 29 2020 · The mixing method is the investigation of the characteristics of alkali-activated cement paste (AACP) with slag and silica fume (SF) of 1 1. The basic mixing method is ASTM C305 which is defined as 1st-cycle. There are three factors considered in this experiment (i) the addition of mixing time (2nd-cycle) (ii) the concentration of activator depending on the amount of mixing water and (iii

Geopolymer cementWikipedia
Geopolymer concrete. There is often confusion citation needed between the meanings of the terms geopolymer cement and geopolymer concrete . A cement is a binder whereas concrete is the composite material resulting from the mixing and hardening of cement with water (or an alkaline solution in the case of geopolymer cement) and stone aggregates.

IV. GGBS Concrete GGBS Proportions On its own ground granulated blast furnace slag (GGBS) hardens very slowly and for use in concrete it needs to be activated by combining it with Portland cement. A typical combination is 50 GGBS with 50 Portland cement but percentages of GGBS 4 anywhere between 20 and 80 are commonly used.
