烧结粉煤灰轻质承重砖研究

研究了以粉煤灰为主要原料,石灰、石膏作掺合料,不掺粘土的烧结粉煤灰轻质承重砖的配制工艺、性能及影响性能的主要因素.结果表明:在不掺粘土的粉煤灰烧结砖中,粉煤灰最大用量可以达94%,砖的强度高于10 MPa,表观密度1 200 kg/m3～1 300 kg/m3,其它各性能均优于同等级的粘土砖.

Study on the Bearing Light Fly Ash Bricks of Sintering

Fly ash has been studied in the bricks as the main raw material,lime and gypsum as admixture. Brick on the preparation process, performance and impact of the major factors has been researched. The results show that the greatest amount of fly ash can be achieved 94% ,but the strength of brick higher than the 10 MPa, the apparent density only about 1 200 kg/m^3 - 1 300 kg/m^3, and the other properties are superior to the same level of clay brick.
