Impermeable material based on lacustrine facies deposition silt and preparation method thereof
The invention discloses an impervious material based on lacustrine facies deposition silt and a preparation method of the impervious material, and belongs to the field of water conservancy and hydropower engineering. The brick is mainly prepared from the following raw materials in parts by weight: 48 to 54 parts of lacustrine facies deposition silt, 40 to 45 parts of gneiss gravel and 5 to 15 parts of modified bentonite. According to the impervious material based on the lacustrine facies deposition silt, the gneiss gravel material serves as a gravel-doped component of the impervious material, is a supporting framework of the impervious material and is high in particle strength, so that the shear strength and the deformation modulus are increased, and shrinkage is reduced; the bentonite is modified to improve the adsorption and water absorption capacity, and the shear strength of the anti-seepage material is improved. The anti-seepage material disclosed by the invention has high compressibility and better dry density, shows certain anti-shearing stability, and is better in anti-seepage effect and better in mechanical property.
本发明公开了一种基于湖相沉积粉土的防渗材料及其制备方法，属于水利水电工程领域。其主要包括以下重量份的原料：湖相沉积粉土48份～54份、片麻岩碎石料40份～45份和改性膨润土5份～15份。本发明的基于湖相沉积粉土的防渗材料，片麻岩碎石料，作为防渗材料的掺砾成分，是防渗材料的支撑骨架，颗粒强度高，以增加抗剪强度和变形模量，减少收缩；通过对膨润土改性提高吸附吸水能力，提高防渗材料的抗剪强度。本发明的防渗材料，具有高等压缩性和更优的干密度，表现出一定的抗剪稳定性，防渗效果更优，力学性能更佳。
