Fast-setting high-strength hydraulic material and preparation method thereof
The invention discloses a fast-setting high-strength hydraulic material, which comprises metakaolin, Portland cement, iron-ore slag powder, gravel, sand, sodium silicate, sodium hydroxide and water. The material ensures fast setting and high strength, and also reduces the manufacturing cost, and has high-strength performances of one hour compressive strength of 12MPa, 3 hour compressive strength of 28MPa, 1-day compressive strength of no less than 42MPa and 7-day of compressive strength of no less than 45MPa. The fast-setting high-strength hydraulic material uses metakaolin as a main mineral filler, which is available, can reach high mechanical strength in a short time, and gains good acid resistance, strong durability, and excellent performance in a very short time.
