针对废弃电路板非金属粉末难以处理的问题，在分析了废弃电路板非金属粉末组成成分的基础上，提出了将其作为一种增强材料掺入到混凝土和砂浆中以增强混凝土和砂浆的强度。结果表明：废弃电路板非金属粉末对混凝土以及砂浆的早期抗压强度提高明显，A种细粉末状废弃电路板非金属粉末在掺量为16．5％时，3 d早期强度提高22％。对砂浆28 d抗压强度也有所提高，故非金属粉末可以作为水泥增强材料。

In view of the problem that waste circuit board nonmetallic powder is difficult to deal with, based on the analysis of composition of waste circuit board nonmetal powder, the paper proposed to take it as a kind of reinforced material which is mixed into concrete and mortar.The experiment results show that the circuit board nonmetallic powder can increase obviously the early compressive strength of concrete and mortar,when non-metallic powder of one kind of fine powdery waste printed circuit boards is mixed at 16. 5%, the early compressive strength after three days increased by 22%.The compressive strength of mor-tar after also inhence after 28 days, so the nonmetallic powder can be used as a kind of cement reinforced material.
