DOI: 10.1038/s41598-017-10306-0
Abstract: SuperAbsorbent Polymers (SAPs) can be applied as an admixture in cementitious materials. As the polymers are able to swell, they will absorb part of the mixing water and can then release that water back towards… read more here.

DOI: 10.3390/ma15103553
Abstract: The acceleration of very early age cement hydration by C-S-H seeding is getting attention from scholars and field applications because the enhanced early age features do not compromise later age performances. This acceleration could be… read more here.
