Antibacterial cement concrete and preparation method thereof
The invention relates to antibacterial cement concrete and a preparation method thereof. The antibacterial cement concrete is prepared from the following raw materials in parts by weight: 12-18 parts of cement, 0.6-1 part of metakaolin, 32-55 parts of quartz sand, 58-120 parts of coarse aggregate, 0.012-0.04 part of an antibacterial agent and 5.5-10.5 parts of deionized water. Nano photocatalytic material is doped into the cement concrete as an antibacterial agent, so that the durability of the cement concrete is not influenced, and an antibacterial effect can be achieved for a long time; artificial coarse aggregate is adopted to replace part of natural coarse aggregate, so that the light receiving area of the antibacterial agent in the cement concrete can be increased; in addition, an antibacterial agent is adopted to form a lubricating film on the surface of the coarse aggregate, so that the lubricating degree of the surface of the coarse aggregate is improved, and the fluidity of cement concrete and the material mixing uniformity are improved.
本发明涉及一种抗菌水泥混凝土及其制备方法，所述抗菌水泥混凝土按重量份的原料配比为：水泥12~18份、偏高岭土0.6~1份、石英砂32~55份、粗骨料58~120份、抗菌剂0.012~0.04份、去离子水5.5~10.5份。本发明采用纳米光催化材料作为抗菌剂掺入水泥混凝土中，既不影响水泥混凝土的耐久性，又能长期起到抗菌的作用；采用人工粗骨料替代部分天然粗骨料，可提升水泥混凝土中抗菌剂的受光面积；采用抗菌剂在粗集料表面形成润滑膜，用于改善粗集料表面的润滑度，提高水泥混凝土的流动性和材料拌合的均匀性。
