Correlation between Rheology of Superplasticized Fresh
The influence of superplasticizer type and content on rheology of mortars and concretes that have different mortar volumes was investigated, cement type and w/c influence was also considered. Rheology results have been evaluated according to the Bingham model. Rheological parameters were measured using BT2 rheometer.
Rheological and physico-chemical study of cement mortars
Mixtures performed using the superplasticizer 2 show a loss of workability as a function of time even stronger than the W/C ratio is low. The spread of reference mortar decreases of 29 mm after 90 minutes of hydration. In presence of 0.3% of admixture (W/C=0.49), loss of spread is 40 mm. It amounts to 49 mm for 0.6% of superplasticizer (W/C=0.46).

Influence of superplasticizers on rheological behaviour
For W/C=0.50 and superplasticizer dosage of 1%, shear resistance continuously increases with time for all tested mortars, but clearly, the highest increase appears for mortar with cement CEM I. The increase of shear resistance for CEM II and CEM III mortars was considerably lower and remained the same for 40 min; then the CEM II mortar shear

the flow behavior of PPC mortar and to find the saturation dosage of superplasticizer in cement mortar of cement to sand proportion 1:1.5. Main parameters which affect the concrete flow behavior are paste rheology, aggregate volume fraction and aggregate particle size distribution. So Influence of aggregates and the aggregate-paste

In the presence of a PCE superplasticizer, a competition between welan gum and superplasticizer to adsorb onto cement particles may occur as both polymers have a similar affinity for cement surface in the range of dosage of polymers normally used in concrete (see Figure 20.5). In this situation, yield stress would increase because of bridging
Optimization of superplasticizer in portland pozzolana cement
In this work for preparing mortar and concrete 4 brands of locally available Portland pozzolana cement (PPC) and superplasticizer (SP) belonging to 4 different families namely Polycarboxylate Ether (PCE), Lignosulphate (LS), Sulfonated Naphthalene Formaldehyde (SNF) and Sulfonated Melamine Formaldehyde (SMF) are used.
Isomatcanada.ca - CONCRETE & MORTAR ADMIXTURES
Liquid polycarboxylate-based admixture acting as a concrete superplasticizer, according to ELOT EN 934-2: T3.1 and T3.2. When added during preparation of concrete, it reduces water demand up to 25%. When added to the ready-mixed concrete, it significantly improves its workability (self-compacting concrete), without need for additional water.
ESTIMATION OF SUPERPLASTICIZER DOSAGE TO ACHIEVE DESIRED
Workability of cement mortar and dosage of superplasticizer are affected by various parameters such as water cement ratio, grading of fine aggregate, shape of aggregate, surface characteristic, and volume of aggregate. Therefore,to resolve the problems encountered in development of desired workable mortar, it is necessary to estimate dosage of
