抗菌混凝土的研究

比较了稀土化合物硝酸铈、硝酸镧和银离子抗菌剂的抗菌能力后 ,选取硝酸铈掺入多孔混凝土中测试其抗菌水平。结果显示 :硝酸铈和硝酸镧的抗菌能力与银离子抗菌剂相仿 ;掺有硝酸铈的多孔混凝土的抗菌水平有大幅度提高 。

After comparison of anti-bacteria ability of antiseptic agents among cerium nitrate and lanthanum nitrate of rare earth compounds as well as silverion, cerium nitrate is chosen for adding into porous concrete. The results of anti-bacteria level tests show that anti-bacteria ability of cerium nitrade and lanthnum nitrade is similar to silver ion antiseptic agent. The anti-bacteria level of porous concrete with cerium nitrade is greatly increased. It is preliminarily proved that the anti-bacteria of concrete can be strengthened with rare earth compound.
