The experiment provides reliable data for engineering application practice and provides reference for other related experiment.
By the engineering experience, water cement ratio is controlled in 0.5, the density of concrete generally is 2450 kg/m3, i.e., the cement quality + water + aggregate quality = 2450 kg, reference this relationship can be filling water cement ratio is determined
Code for reference to engineering construction and acceptance of concrete structures (GB50204-92) and "regulations of common concrete mixture ratio design" (JGJ/T55-2000) of the relevant provisions, fcu,o≥fcu,k+1.645σ type, fcu, k stand for cube compressive strength standard values for the design of concrete, MPa, fcu, o stand for the concrete strength, MPa, the standard deviation σ stand for concrete strength, σ value selected according to table 2[3].
