High crack resistance concrete
The invention discloses high crack resistance concrete, which is formed by the following raw materials in parts by weight: 2-4 parts of volcanic ash, 4-5 parts of aluminium dihydrogen phosphate, 2-3 parts of bamboo carbon fiber, 10-14 parts of tetra calcium aluminoferrite, 3-5 parts of basalt fiber, 300-400 parts of ordinary portland cement,400-450 parts of fine sand, 350-400 parts of macadam, 15-20 parts of flax chips, 2-3 parts of calcium formate, 0.3-0.6 part of ethidene diamine, 5-10 parts of bone black, 1-2 parts of urea, 2-3 parts of glycerol triacetate, 0.4-1 part of isothiazolinone, 5-10 parts of precipitated barium sulphate, 1-2 parts of diammonium phosphate, 1-2 parts of sodium carboxymethylcellulose, and 0.1-0.4 part of hydroxyl silicone oil. The concrete provided by the invention is added with fiber, so that the separation tendency of the concrete is prevented and inhibited, cracks generated after concrete casting can be reduced and even completely eliminated, and thus the concrete has the advantages of high compactness, high strength, good durability and the like; accessory ingredient is added to play a role in water reduction and viscidity increasing capacity, and the anti-cracking-coefficient of the concrete is improved.
