Originální abstrakt

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.

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.
