Freeze-thaw resistant vegetation concrete and preparation method thereof
The invention relates to the field of vegetation concrete, in particular to freeze-thaw resistant vegetation concrete and a preparation method thereof. The invention relates to freeze-thaw resistant vegetation concrete, which comprises 20-30 parts of cement; 100 to 130 parts of aggregate and 55 to 70 parts of mineral powder; 20-30 parts of a plant growing base material; the aggregate comprises a coarse aggregate and a fine aggregate, the coarse aggregate comprises an aggregate matrix and a hydrophobic aerogel coating layer coating the surface of the aggregate matrix, and the hydrophobic aerogel coating layer is prepared by coating polylactic acid/cellulose aerogel. According to the technical scheme, the surface of the aggregate is modified, water is prevented from permeating into the aggregate, damage to the structure of the aggregate in the follow-up freezing and thawing environment is improved, meanwhile, the adopted aerogel materials are polylactic acid and cellulose materials, plants can effectively adsorb residual organic matter in the concrete in the actual growth process, and the service life of the concrete is prolonged. Therefore, more living space is obtained, and growth space is provided for growth of plants.
本申请涉及植生混凝土领域，更具体地说，它涉及一种抗冻融植生混凝土及其制备方法。一种抗冻融植生混凝土，水泥20～30份；骨料100～130份矿粉55～70份；植生基材20～30份；所述骨料包括粗骨料和细骨料，所述粗骨料包括骨料基体和包覆于骨料基体表面的疏水气凝胶包覆层，所述疏水气凝胶包覆层为聚乳酸/纤维素气凝胶包覆制备而成。本申请技术方案通过对骨料表面进行改性处理，防止水分在骨料内部的渗透，从而改善后续冻融环境下对骨料结构的破坏，同时本申请采用的气凝胶材料为聚乳酸和纤维素材料，植物在实际生长过程中能有效吸附混凝土中残留的有机质，从而获得较多的生活空间，从而为植物的生长提供生长空间。
