specific Embodiment 1
[0015] A large-volume low-cement concrete formula for anchorage, which is composed of the following raw materials in parts by weight: 100 parts of P.Ⅱ 52.5 grade cement; 90 parts of S95 grade mineral powder; 130 parts of F class I fly ash; 700 parts of sand in river sand 1000 parts of gravel with a particle size of (5-25) mm; 130 parts of water; 3.5 parts of PCA® (I) carboxylic acid high-performance water reducer (developed by Jiangsu Academy of Building Research).
specific Embodiment 2
[0017] A large-volume low-cement concrete formula for anchorage, which is composed of the following raw materials in parts by weight: 136 parts of P.Ⅱ 52.5 grade cement; 98 parts of S95 grade mineral powder; 156 parts of F class I fly ash; 763 parts of river sand 1099 parts of gravel with a particle size of (5-25) mm; 148 parts of water; 3.9 parts of PCA® (I) carboxylic acid high-performance superplasticizer (developed by Jiangsu Academy of Building Research).
specific Embodiment 3
[0019] A large-volume low-cement concrete formula for anchorage, which is composed of the following raw materials in parts by weight: 150 parts of P.Ⅱ 52.5 grade cement; 110 parts of S95 grade mineral powder; 170 parts of F class I fly ash; 800 parts of sand in river sand 1200 parts of gravel with a particle size of (5-25) mm; 160 parts of water; 4.5 parts of PCA® (I) carboxylic acid high-performance superplasticizer (developed by Jiangsu Academy of Building Research).
[0020] The advantages of the present invention are: the 7d compressive strength of the concrete produced by this formula can reach 35.4, and the 28d compressive strength can reach 55.3. Under the premise of the target, the amount of cement per cubic meter was greatly reduced (150kg / m 3 Within), greatly reducing the production cost of the enterprise.
