High-performance concrete material for anchoring area of expansion joint and preparation method of high-performance concrete material
The invention relates to the technical field of concrete, and particularly discloses a high-performance concrete material for an expansion joint anchoring area, which is prepared from the following raw materials in parts by weight: 45 to 50 parts of Portland cement, 15 to 20 parts of fine aggregate, 20 to 25 parts of coarse aggregate, 10 to 15 parts of modified lignin blended flaky boron nitride agent, 3 to 5 parts of sodium carboxymethyl cellulose, 2 to 4 parts of water reducing agent and 40 to 50 parts of water. According to the high-performance concrete material disclosed by the invention, Portland cement is matched with fine aggregate and coarse aggregate to be blended and optimized through sodium carboxymethyl cellulose and a water reducing agent, and meanwhile, the added modified lignin is blended with a flaky boron nitride agent to be dispersed into a matrix, so that the anti-seepage, anti-cracking and strength properties of the matrix are improved, and the coordination effect of the two is optimized; meanwhile, the glass fiber modifier and the modified silicon nitride which are added into the product are coordinated and synergistic, so that the anti-seepage, anti-cracking and strength coordination effects of the product are further enhanced, and the stability of the product under the conditions of acid corrosion and high temperature is optimized.
本发明涉及混凝土技术领域，具体公开了一种伸缩缝锚固区用高性能混凝土材料，包括以下重量份原料：硅酸盐水泥45～50份、细骨料15～20份、粗骨料20～25份、改性木质素调和片状氮化硼剂10～15份、羧甲基纤维素钠3～5份、减水剂2～4份、水40～50份。本发明高性能混凝土材料采用硅酸盐水泥配合细骨料、粗骨料通过羧甲基纤维素钠、减水剂调配优化，同时加入的改性木质素调和片状氮化硼剂分散到基体中，改进基体的防渗抗裂、强度性能，优化二者的协调性效果，同时产品中加入的玻璃纤维调节剂、改性氮化硅二者协调增效，进一步的增强产品的防渗抗裂、强度协调效果，以及优化产品的酸腐、高温条件下稳定性。
