Study on Preparation and Properties of Sintered Brick from Multi-Source Solid Waste

The recycling of construction waste and the use a new sintering process in field sintered bricks can greatly solve problems clay resource depletion, soil structure destruction, high CO2 emissions that always limit development brick field. study was carried out using an orthogonal experiment to derive optimal mix ratio for preparation bricks, subsequently, were prepared ratio. experimental results show maximum compressive strength (MRB brick) high-temperature is 8.1 MPa, water absorption 11. When glass slag mixed with 10%, it better fluxing effect by mixing (MGB bricks), so MGB have higher densification. 32.9% 3.5% lower than MRB brick. MGS Yellow River sedimentary sand into bricks. increased replacement rate sand, when reached 16%, 88.9%, reduced 4.6% compared mechanism had significant effects on strength, weathering resistance, frost resistance microwave has characteristics efficiency, uniform heating, selective low thermal inertia, which increase 4.6%, reduce 12.9%, shorten time 43.6%, improve resistance.
