Abstract
New photocatalytic cement compositions are disclosed. These contain a superfluidizing agent, a cellulosic ether with a defined viscosity, an adhesive polymer, and a lattice, as well as other standard ingredients for photocatalytic cements. The compositions are free of starch and its chemically modified derivatives.
