Problems solved by technology

[0003] However, compared with natural sand, machine-made sand still has an obvious gap, especially in the particle gradation and mud content and powder content. As a fine aggregate, it often leads to more uncontrollable factors in concrete production. The probability of various problems also increases, such as poor packaging of concrete prepared with machine-made sand, resulting in scattered concrete, increased admixtures, and increased concrete loss over time.

Description

technical field [0001] The invention belongs to the technical field of building materials, and particularly relates to a machine-made sand conditioner and a preparation method and application thereof. Background technique [0002] With the increasing demand for concrete, machine-made sand has gradually become a substitute for natural sand due to the limited storage of natural sand. Machine-made sand is the removal of weathering products from the parent rock ore and then mechanically crushing and sifting it into stone particles with smaller particle sizes. Because machine-made sand has a wide range of sources, low cost, large output, little impact on the environment, and easy adjustment of gradation Therefore, it has a good application prospect as a concrete fine aggregate. [0003] However, compared with natural sand, machine-made sand still has obvious gaps, especially in terms of particle gradation, mud content and powder content. The probability of various problems also...
