Effect of Gypsum-Hemihydrate Ratio in Cement on ...

1997-03-01  In the present paper, the results of an experimental investigation on the effect of the gypsum-hemihydrate ratio in cement on the rheological properties of fresh concrete are presented. For the most reactive type of cement with a high content of both C3A and alkalies, a reduced gypsum-hemihydrate ratio from 80/20 to 20/80 reduced the yield stress, while the plastic viscosity was not

Role of Gypsum in Cement and its Effects - The Constructor

2018-09-27  In the manufacture process of cement, clinkers are formed. These cement clinkers are cooled down and added with small amount of gypsum. The mixture then sent to final grinding process. For ordinary Portland cement it remains between 3 to 4% and in case of Quick setting cement it can be reduced up to 2.5%.

Gypsum Content - an overview ScienceDirect Topics

Increasing the gypsum content increases the C/S ratio of the C-S-H formed, which corresponds to a decrease in the intrinsic strength of the C-S-H gel. This occurs due to excessive gypsum, which reacts with the C-S-H gel formed and changes its structure. Shiyuan (1982) reported that the strength of cement pastes containing 20% fly ash could be improved by increasing the gypsum content. Early ...

Clinker: compositional parameters - Understanding Cement

Lime Saturation Factor (LSF) The Lime Saturation Factor is a ratio of CaO to the other three main oxides. Applied to clinker, it is calculated as: LSF=CaO/ (2.8SiO 2 + 1.2Al 2 O 3 + 0.65Fe 2 O 3) Often, this is referred to as a percentage and therefore multiplied by 100. The LSF controls the ratio of alite to belite in the clinker.
