Original Abstract

The aim of this paper is to study the effect of polyethylene glycol with relative molecular weight ranging between 400–20000 g/mol on the properties of geopolymer mortars composed of metakaolin and sodium silicate. Polyethylene glycol was added in the amount of 0.5 to 10% by mass of metakaolin. After 28 days of curing at ambient conditions, different tests were carried out: physico-chemical (density, porosity), mechanical (flexural and compressive strength). The results showed that a maximum compressive strength of 23.9 MPa and a maximum flexural strength of 2.9 MPa were achieved by adding 10% of PEG 400.

Polyethylene glycol was added in the amount of 0.5 to 10% the mass of metakaolin. After 28 days of interpretation at ambient conditions, different tests were carried out: physico-chemical (density, of the porosity), mechanical (flexural and compressive strength). The results that showed it, and the maximum compressive strength of 14.9 MPa flexural strength and maximum of 2.9 MPa were achieved by adding 10% of PEG 400.
