| Abstract: | The load-bearing standard brick was prepared by coal ash from a power plant of Baotou by wet thermo-curing method under alkaline compound activator，with addition of small quantity of cement and river sand.Through the single-factor experiments，the bricks with fly ash contents of up to 58.3% were obtained and its compressive strength of the brick reached 18.7 MPa，and bending strength 3.4 MPa at thermo-curing of 28 d.Then，some factors influencing the hardness of the brick were analyzed． |
