Anti-freezing and anti-cracking concrete suitable for low-temperature environment and preparation method of anti-freezing and anti-cracking concrete
The invention discloses anti-freezing and anti-cracking concrete suitable for a low-temperature environment and a preparation method thereof, and the anti-freezing and anti-cracking concrete comprises the following raw materials in parts by weight: 350-380 parts of cement, 75-95 parts of fly ash, 30-40 parts of silica fume, 650-700 parts of river sand, 1030-1080 parts of gravel, 5.5-6.5 parts of a water reducing agent, 180-190 parts of water and an anti-freezing and anti-cracking agent, the anti-freezing and anti-cracking agent comprises 25-35 parts of an anti-freezing early strength component, 30-40 parts of a low-temperature anti-cracking component and 0.8-1.5 parts of organic fibers. The anti-freezing and anti-cracking concrete prepared by the invention can be used in a low-temperature environment of-5 DEG C to-15 DEG C, and effectively solves the problem that the concrete is easy to frost and crack in the low-temperature environment.
本发明公开了一种适用于低温环境的防冻抗裂混凝土及其制备方法，防冻抗裂混凝土包括以下按重量份数计的原料：水泥350～380份、粉煤灰75～95份、硅灰30～40份、河砂650～700份、碎石1030～1080份、减水剂5.5～6.5份、水180～190份以及防冻抗裂剂，所述防冻抗裂剂包括防冻早强组分25～35份、低温抗裂组分30～40份及有机纤维0.8～1.5份。本发明制备的防冻抗裂混凝土能够用于‑5℃～‑15℃低温环境下，有效解决低温环境混凝土易冻坏及易开裂问题。
