氧化硅20份
氧化镁15份
三氧化二钛10份
其他均同实施例1，根据《GB 13544-2011》进行抗冻融检测后，15次循环冻融后未出现冻坏现象，抗压强度损失率为6%。
对比例1
不在砖坯中加入实施例3的抗冻剂，4次循环冻融后出现冻坏现象，《GB 13544-2011》进行抗冻融检测后，抗压强度损失为32%。
对比例2
掺入实施例3的抗冻剂为砖坯质量分数的3%，9次循环冻融后出现冻坏现象，《GB13544-2011》进行抗冻融检测后，抗压强度损失为24%。
上述实施例仅为说明本发明的技术构思及特点，并不能以此限制本发明的保护范围，凡根据本发明精神实质所作的修改和变化，均涵盖在本发明的保护范围之内。
