摘要：

The effect of the addition of organic compounds (OC) an ordinary white Portland cement (WPC), on the properties such as compressive strength, fluidity, setting time, porosity and heat of hydration has been studied by adding 0.10-0.80 weight % of OC into the cement. The mixture of organic compounds obtained from a thermo-depolymerization of waste polyethylene (WP) and hydroxylation was composed by alcohols, alkenes and alkalies. The compressive strength was significantly dependent on the amount of OC. The highest value (45.3 MPa) was found by adding 0.35 wt.% of the OC. The porosity of the modified WPC did not change in the range 0-0.4 wt.% OC, however from 0.5-0.8 wt.% OC caused a linear increase of the porosity.
