Abstract

The influence of 5-7 polymethylene naphthalene-α-sulphur natrium (α-PNS-1) on the dispersing composition of cement suspension is investigated. On the basis of the sedimentative and electronic and microscopic researches it is shown that case-harden cementing and plasticization effects of α-PNS-1 on cement systems are caused by significant increase in system of a share of cement particles with smaller radiuses when using α-PNS-1 as admixture.
