Low-shrinkage, low-viscosity and ultrahigh-strength concrete and preparation method thereof
The invention relates to the field of building materials, and particularly discloses low-shrinkage, low-viscosity and ultrahigh-strength concrete and a preparation method thereof. The low-shrinkage, low-viscosity and ultrahigh-strength concrete is prepared from the following raw materials in parts by weight: 320 to 450 parts of cement, 300 to 420 parts of stone, 600 to 860 parts of sand, 260 to 400 parts of water, 40 to 60 parts of silica fume, 15 to 32 parts of mineral powder, 35 to 50 parts of a water reducing agent, 40 to 70 parts of a shrink-proof body and 95 to 105 parts of a low-viscosity modified material. The low-viscosity modified material comprises fly ash with a hollow microsphere structure. The preparation method comprises the following steps of: S1, primary mixing; S2, secondary mixing; and S3, blending. The low-shrinkage, low-viscosity and ultrahigh-strength concrete has the advantages that the viscosity of the ultrahigh-strength concrete is reduced, and pump conveying and construction are facilitated.
本申请涉及建筑材料领域，具体公开了一种低收缩低粘度超高强混凝土及其制备方法。一种低收缩低粘度超高强混凝土，由包含以下重量份的原料制成：水泥320‑450份、石料300‑420份、砂600‑860份、水260‑400份、硅灰40‑60份、矿石粉15‑32份、减水剂35‑50份、防缩体40‑70份、低粘度改性料95‑105份；所述低粘度改性料包括空心微珠结构的粉煤灰；其制备方法为：S1、一次混合；S2、二次混合；S3、共混。本申请的低收缩低粘度超高强混凝土具有降低超高强混凝土的粘性，便于泵输送和施工的优点。
