The invention discloses a formula of low-shrinkage low-viscosity high-strength concrete. The concrete comprises the following components in parts by weight: 300 to 350 parts of cement, 80 to 100 parts of water, 300 to 330 parts of broken stone, 310 to 340 parts of river sand, 70 to 85 parts of fly ash, 50 to 65 parts of metakaolin, 50 to 70 parts of silica fume, 35 to 50 parts of silica fume, 8 to 16 parts of steel fiber, 30 to 45 parts of phosphogypsum, 15 to 20 parts of a water reducing agent and 10 to 16 parts of an expanding agent. The invention further discloses a preparation method of the low-shrinkage low-viscosity high-strength concrete. The preparation method comprises five preparation steps. The low-shrinkage low-viscosity high-strength concrete is composed of the cement, water, broken stone, river sand, fly ash, metakaolin, silica fume, silica fume, steel fiber, phosphogypsum, water reducing agent and expanding agent, and the concrete prepared according to the formula is compact in internal accumulation, low in porosity, high in strength, high in shrinkage resistance, high in strength and low in viscosity.
本发明公开了一种低收缩低粘度高强度混凝土的配方，以重量份计包括如下组份：300‑350份的水泥、80‑100份的水、300‑330份的碎石、310‑340份的河砂、70‑85份的粉煤灰、50‑65份的偏高岭土、50‑70份的硅灰、35‑50份的微硅粉、8‑16份的钢纤维、30‑45份的磷石膏、15‑20份的减水剂、10‑16份的膨胀剂；本发明还公开了一种低收缩低粘度高强度混凝土的制备方法，包括五个制备步骤。本发明提供的一种低收缩低粘度高强度混凝土的配方由水泥、水、碎石、河砂、粉煤灰、偏高岭土、硅灰、微硅粉、钢纤维、磷石膏、减水剂以及膨胀剂构成，通过本发明的配方所配置出来的混凝土内部堆积密实，孔隙率较低，强度较高，抗收缩性较好，粘度较低。
