Embodiment 1
[0022]1) A concrete with the functions of reinforcement, internal maintenance and shrinkage compensation, consisting of 42.5 ordinary Portland cement, silica fume, mineral powder, machine-made sand, stones, water reducing agent, internal curing agent, organic early-strength components, Composed of water and other raw materials, the components weighed per cubic meter are: 380kg of cement, 30kg of silica fume, 70kg of mineral powder, 800kg of machine-made sand, 970kg of stones, 11.9kg of internal culture-water reducing agent, and 155kg of water.
[0023] 2) The internal curing agent is prepared from the original liquid of the internal curing agent and water at a ratio of 1:14. When preparing the internal curing agent, the original liquid and water are stirred together for 5-10 minutes, and the internal curing agent is formed after saturated water absorption for 0.5 hours.
[0024] 3) Compound the internal curing agent and the organic early-strength component at a ratio of 20:1, a...
Embodiment 2
[0032] 1) A concrete with the functions of reinforcement, internal maintenance and shrinkage compensation, consisting of 42.5 ordinary Portland cement, silica fume, mineral powder, machine-made sand, stones, water reducing agent, internal curing agent, organic early-strength components, Composed of water and other raw materials, the components weighed per cubic meter are: 440kg of cement, 30kg of silica fume, 70kg of mineral powder, 760kg of machine-made sand, 930kg of stones, 22.4kg of internal culture-water reducing agent, and 155kg of water.
[0033] 2) The internal curing agent is prepared from the original liquid of the internal curing agent and water at a ratio of 1:14. When preparing the internal curing agent, the original liquid and water are stirred together for 5-10 minutes, and the internal curing agent is formed after saturated water absorption for 0.5 hours.
[0034] 3) Compound internal curing agent and organic early-strength component at a ratio of 20:1, and stir...
