It was found that a good agreement exists between the resul

Implantable and Wearable Bionicsther is a semi-anionic SAP, which contains an anionic moiety (polyacrylamide). As expected, the SAPs with anionic moieties show a higher degree of swelling in all environments. The cement pastes dosed with the semi-anionic SAP show a lower calcium concentration in the pore solution. These cement pas

Establishment of Anaesthesiology in Germany,ibution of initial dry SAP. This fact suggests that the SAP particles broke away during mixing. The centroids of SAP particles were distributed as to form a regular pattern. A procedure to evaluate the median distance from a given location to the surface of the nearest SAP particle was proposed by c

The hardened specimens were subjected to compressive strength and water absorption tests at the varied curing ages for the performance assessment of the binder types and SAP grain sizes in HPC

There were properties such as compressive strength, modulus of elasticity, shrinkage as well as uniaxial creep deformations investigated in the laboratory. Afterward parameters of long-term properties were determined. The obtained results showed that after approximately 90 days of load

Cement pastes with and without superabsorbent polymers (SAPs) were produced with Portland cement CEM III-B 42.5 N and superplasticizer (Glenium 51, 35% conc.). SAPs have proven to be quite effective in the mitig
