答案：【计分规则】: After the cube specimen with 100mmside length being cured for 28 days under standard conditions (temperature 20 ± 3 ℃, relative temperature ≥ 90%), following the standard test method (loading rate 0.3~1.0N/mm2/s): the upper and lower surfaces of the specimens are not coated with lubricant and loaded continuously until the specimens are damaged. The measured compressive strength is the characteristic cubic compressive strength of concrete.
