Early-strength cement-based grouting material as well as preparation method and application thereof
The invention discloses an early-strength cement-based grouting material as well as a preparation method and application thereof. The invention provides an early-strength cement-based grouting material. The early-strength cement-based grouting material is prepared from the following components in parts by weight: 80-100 parts of water, 25-40 parts of P.042.5 cement, 38-53 parts of mineral powder, 1-10 parts of fly ash, 4-8 parts of natural gypsum powder, 4-8 parts of slaked lime, 3-6 parts of solid sodium silicate and 2-6 parts of salty mud. According to the early-strength cement-based grouting material, mineral powder, coal ash, natural gypsum powder, solid sodium silicate, salty mud and other admixtures are added, an alkaline environment is provided for cement hydration of the cement-based grouting material, and therefore the early strength of cement soil around a pile body is improved.
早强型水泥基灌浆料及其制备方法和应用。本发明提供了一种早强型水泥基灌浆料，其由以下重量组分组成：水80‑100份，P.042.5水泥25‑40份，矿粉38‑53份，粉煤灰1‑10份，天然石膏粉4‑8份，熟石灰4‑8份，固体硅酸钠3‑6份，盐泥2‑6份；本发明要解决的技术问题是一种早强型水泥基灌浆料，通过添加矿粉、粉煤灰、天然石膏粉、固体硅酸钠和盐泥等掺合料水泥基灌浆料的水泥水化提供碱性环境，从而提高桩身周围的水泥土早期强度。
