Abstract
A method for preparing a high-performance compressed desert sand concrete is provided. The method includes: mixing a cement, a coarse aggregate, a fine aggregate, and water, and subjecting a mixture to compression casting, and curing in sequence to obtain the high-performance compressed desert sand concrete; where the compression casting is conducted at a pressure of not less than 2 MPa for not less than 2 min.
Claims7
A method for preparing a high-performance compressed desert sand concrete, comprising the following steps:
- mixing a cement, a coarse aggregate, a fine aggregate, and water, and subjecting a resulting fresh concrete mixture to compression casting, and curing in sequence to obtain the high-performance compressed desert sand concrete;
- wherein
- the compression casting comprises filling of a steel mold with the resulting fresh concrete mixture while compression;
- the fine aggregate comprises river sand and desert sand at a mass ratio of 0-99:1-100;
- the compression casting is conducted at a pressure of not less than 2 MPa for not less than 2 min;
- and
- a mass ratio of the cement to the coarse aggregate is in a range of 1:0.5-10.
