Abstract: The influence of lime , cement , curing temperature and time on the mechanical property of silt baking-free bricks was systematically investigated .Subsequently , the frost resistance of silt baking-free bricks was studied .The results show that 30%-40% of lime leads to the higher compressive strength . The increasing content of cement contributes to better mechanical performance and frost resistance . Curing temperature is set at 80 ℃for economic considerations .

Key words: silt;baking-free brick;lime;cement;curing;frost resistance
