13/09/2013 · It is rejected due to excessive slump, as it is obvious something happened in the batch to increase slump. Now, consider adding superplasticizer at the readymix plant. The first four trucks would show up onsite at slump; the fifth at inches. This indies the same issue in the batch and the truck would be rejected.

Use of Water Reducers, Retarders, and Superplasticizers. Introduction. Many important characteristics of concrete are influenced by the ratio (by weight) of water to cementitious materials (w/cm) used in the mixture. By reducing the amount of water, the cement paste will have higher density, which results in higher paste quality.

Use of readymixed concrete plant sludge water in Details of the concrete mix proportions are presented in Table 1, in which CC denotes the control concrete mixed with tap water, F represents a concrete containing fly ash as a cement replacement at 20 wt%, S denotes a concrete mixed with superplasticizer at 1 wt%, and W represents concrete prepared using sludge water without fly ash or ...

This is because the problem of cementsuperplasticizer compatibility has many dimensions to it. On the one hand, there is the composition of the water reducer, as discussed above. On the other end of the spectrum is the composition of cement, particularly the relative proportions of C3A, alkalis and C3S in the cement.
