Preparation method of high-performance compressed desert sand concrete
The invention belongs to the technical field of building materials, and particularly relates to a preparation method of high-performance compressed desert sand concrete. The preparation method of the high-performance compressed desert sand concrete provided by the invention comprises the following steps: mixing cement, coarse aggregate, fine aggregate and water, and sequentially carrying out compression pouring and maintenance to obtain the high-performance compressed desert sand concrete, the pressure of compression pouring is 2 MPa or above, and the time of compression pouring is 2 min or above. The desert sand is used for replacing natural river sand to serve as fine aggregate, concrete defects caused by direct use of the desert sand for replacing the natural river sand can be effectively reduced through compression pouring, and 100% replacement of the natural river sand by the desert sand is achieved on the premise that the excellent mechanical property and durability of desert sand concrete are guaranteed; the obtained high-performance compressed desert sand concrete is improved in mechanical property and durability and good in comprehensive performance.
本发明属于建筑材料技术领域，具体涉及一种高性能压缩沙漠砂混凝土的制备方法。本发明提供的高性能压缩沙漠砂混凝土的制备方法，包括以下步骤：将水泥、粗骨料、细骨料和水混合后依次进行压缩浇筑和养护，得到高性能压缩沙漠砂混凝土；所述压缩浇筑的压力为2MPa以上，压缩浇筑的时间为2min以上。本发明利用沙漠砂替代天然河砂作为细骨料，通过压缩浇筑，可以有效减少直接使用沙漠砂替代天然河砂所带来的混凝土缺陷，在确保沙漠砂混凝土的力学性能和耐久性优异的前提下，实现了沙漠砂100％替代天然河砂，得到的高性能压缩沙漠砂混凝土力学性能和耐久性提高，综合性能良好。
