Abstract
The invention discloses a high-performance cold-resistant and anti-freezing concrete which comprises the following components in parts by weight: 15-20 parts of stones; 15-20 parts of sand; 60-80 parts of cement; 8-12 parts of a mixing agent; 8-12 parts of an adhesive; 10-15 parts of a filling agent; 30-40 parts of water. The invention screens out the stones with large particle size and avoids the generation of gaps caused by the compression and the mixing of the stones with large particle size after the concrete is solidified. The invention washes and dries the stone and sand raw material, removes the impurities on the surfaces of the stone and sand, and increases the adhesive strength of the stone and sand and the mixed material. The mixture ratio of the adhesive and the filler of the admixture ensures the stability and the strength of the concrete after solidification and prevents low-temperature cracking.
