Partial substitution of Cement in Concrete by Finely Ground Brick Body

by Libuše Beckerová, Gergely Bölckei and Jirí Brožovský

Abstract
Brick chippings are the waste which can partially substitute the cement. Therefore this waste is utilized, in light of the environment, into the useful new product - the concrete. The finely ground brick body is characterized by certain pozzuolana activity which enables the partially substitution of the energetically demanding binder which is the cement. The paper indicates the observations concerning the tests of concrete in which the cement was substituted by 10% and 20% of finely ground brick bodies from the brick plants Kryry and Šlapanice.

KEYWORDS: brick body, concrete, additive to concrete, pozzuolana activity.
