    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.

    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

    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

    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
