Embodiment 1
[0034] A certain batch of air-entrained concrete is measured according to the method for rapidly predicting the dry density of the air-entrained concrete, the moisture content and the water absorption rate after leaving the kettle provided by the present invention.
[0035] The measurement results are as follows:
[0036] The calculation results when a=1.8 are shown in the table below:
[0037]
[0038] The calculation results when a=2.0 are shown in the table below:
[0039]
[0040] The calculation results when a=2.2 are shown in the table below:
[0041]
[0042] Based on the above data, the dry density of the air-entrained concrete, the water content and water absorption after leaving the kettle are shown in the following table:
[0043]
[0044] According to GB / T11969-2008 "Autoclaved Air-entrained Concrete Performance Test Method", the dry density, water content and water absorption of the air-entrained concrete specimens were measured.
