Desert aeolian sand modified concrete technology
The invention relates to a desert aeolian sand modified concrete technology which comprises the following steps: uniformly mixing and stirring a first raw material component to obtain a mixed material; adding the second raw material component into the mixed material, then stirring for a preset time, then loading into a mold, and carrying out molding maintenance to obtain desert aeolian sand modified concrete; wherein the first raw material component comprises an excitant, cement and fibers, the second raw material component comprises desert aeolian sand and water, the mass ratio of the excitant to the cement to the fibers is 1 : (10-12) : (2-3), the mass ratio of the desert aeolian sand to the water is (1.2-2) : 1, and the mass ratio of the first raw material component to the second raw material component is 1 : (1.6-1.8). According to the invention, the desert aeolian sand, the excitant, the cement and the fibers are adopted as raw materials, the 7-day compressive strength of the prepared desert aeolian sand modified concrete can reach 30 MPa or above, the breaking strength can reach 10 MPa or above, the volume shrinkage rate is low, and durability is good.
本发明涉及一种沙漠风积沙改性砼技术，包括步骤：将第一原料组分混合拌匀，得到混合材料；将第二原料组分加入混合材料，之后搅拌预设时间，然后装模并进行成型养护，得到沙漠风积沙改性砼；其中，第一原料组分包括激发剂、水泥和纤维；第二原料组分包括沙漠风积沙和水；激发剂、水泥和纤维的质量比为1：(10‑12)：(2‑3)；沙漠风积沙和水的质量比为(1.2‑2)：1；第一原料组分和第二原料组分的质量比为1：(1.6‑1.8)。本发明采用沙漠风积沙、激发剂、水泥和纤维为原料，制备得到的沙漠风积沙改性砼7天抗压强度可达30MPa以上，抗折强度可达10MPa以上，体积收缩率低且耐久性好。
