Характеристики обожженного глиняного кирпича с добавлением доломитового порошка

Abstract

The paper analyses the effect of dolomite powder on properties and durability of clay brick. Clay bricks were made from the mix containing from 10 to 30 % of waste dolomite powder and fired at 1000 ?C temperatures. In this case, clay bricks density is 1.55 – 1.75 g/m3, compressive strength 14 – 28 MPa, water absorption 15.3 – 19.7 %, total porosity 31,0 – 40.4 %, durability (resistance to freezing and thawing) not less than 25 cycles.
