| Abstract |
| Effect of polyethylene glycol addition to ordinary Portland cement
on its properties like heat of hydration, setting time, compressive
and tensile strength has been studied by adding 0.1 to 5.0 percent
additive by weight of cement. Corrosion resistance of the
resulting product has been tested against sea water and 0.1 and
1.0 N HCI and H2S04 respectively. Water absorption/open porosity
have also been determined and the microstructures examined.
It was observed that strength, hardness, toughness and corrosion
resistance increase up to 3.0% addition of polyethylene glycol in
ordinary Portland cement. The polymeric phase was interspersed
in cement causing decrease in water absorption/porosity and
also its interaction with hydrating cement caused additional bond
formation leading to increase in strength. |
