Photocatalytic cement concrete and preparation method thereof
The invention relates to photocatalytic cement concrete and a preparation method thereof. The photocatalytic cement concrete is prepared from the following raw materials in parts by weight: 22-35 parts of cement, -parts of machine-made sand, 104-220 parts of coarse aggregate, 0.02-0.11 part of boron carbon nitrogen, 0.016-0.05 part of nano montmorillonite and 9.5-21 parts of deionized water. Wherein the coarse aggregate is formed by mixing natural coarse aggregate and artificial coarse aggregate. The artificial coarse aggregate is adopted to replace part of the natural coarse aggregate, so that the natural coarse aggregate can be saved, and the pollution reduction effect of the photocatalytic cement concrete can be remarkably improved; the boron-carbon-nitrogen nano photocatalytic materialis respectively doped into cement, water and aggregate, so that the dispersity of boron-carbon-nitrogen in concrete is effectively improved, more reaction active sites are exposed, and the pollutantdegradation efficiency can be remarkably improved.
本发明涉及一种光催化水泥混凝土及其制备方法，所述光催化水泥混凝土按重量份的原料配比包括：水泥22~35份、机制砂55~105份、粗骨料104~220份、硼碳氮0.02~0.11份、纳米蒙脱土0.016~0.05份、去离子水9.5~21份；所述粗骨料由天然粗骨料和人工粗骨料混合而成。本发明采用人工粗骨料替代部分天然粗骨料，既可以节省天然粗骨料，又可显著提升光催化水泥混凝土的降污效果；将硼碳氮纳米光催化材料分别掺入水泥、水和骨料中，有效改善硼碳氮在混凝土中的分散性且暴露出更多的反应活性位点，可显著提高降解污染物的效率。
