How Super Are Superplasticizers?| Concrete Construction

May 01, 1982 · Superplasticizers transform stiff, low-slump concrete into flowing, pourable, easily placed concrete. They can improve workability, speed finishing, increase strength, conserve cement and help reduce shrinkage and thermal cracking. However, because of their brief history, questions and doubts about their use still exist.

Selection of Superplasticizers for High-Performance Concrete

Superplasticizers are used to fluidify the concrete in the field. Most of the superplasticizers helped to maintain high slump values for a time of 30 to 45 minutes. But some of the Portland cement do no behave well with the use of superplasticizers. This problem is …

When and how self-cleaning of superhydrophobic surfaces works

Many superhydrophobic surfaces rely on microstructures . As a model, we investigated microstructured superhydrophobic surfaces that were made of SU-8 micropillars (rectangular, 10-μm height with 5 × 5–μm 2 top areas; center-center distance of pillars, 20 μm) on glass slides using photolithography. The SU-8 micropillar surfaces were ...
