Experimental investigation on properties of concrete incorporating TiO2

Abstract

One of the main issuesin recent years has been the deteriorating air quality. Because of the metropolises, rapid urbanization, the problem of airborne pollution is increased. Heavy traffic contributes to air pollutants which leads to environmental deterioration and public health problems. Titanium dioxide has the ability to self clean, depollute, and even degrade organic material on surfaces since photocatalyst is used. It is an ecofriendly and sustainable material which has broader application
in construction sector. The work consists of 0%, 1%, 2%, 3%, 4% and 5% Titanium dioxide replacement by the weight of cement. The control mix used in the studyis M40 grade. The compressive strength and split tensile strength at 28 days are obtained as 59.33 N/mm2 and 4.43 N/mm² respectively. The strength was found to be more at 3% of replacement of TiO₂.
