Is the air-entraining agent you use for wet-mixed mortar solid? Obviously, this is the problem of the dispersibility of the air-entraining agent. We usually stir for 3 minutes, 30 seconds is not uniform enough.

The concrete mixing station for wet-mixed mortar has a natural monopoly, and the cost is low, mainly because of the difficult transportation. It must be pushed together with mechanical spraying. There is no way to apply it only manually.

The compressive strength is the same, and applying on the wall is fine, but only the mortar on most of the test pieces is easy to fall off under the normal maintenance condition, and the 14d will fall off with a slight break. I am still determining the specific reason.

Too much cement and the sand is too fine. Since it cracks in first layer before the initial setting, there are some factors need to be considered:Water retention rate, admixture amount, and silt content in the sand.

If you are using the AB compound type, you'd better replace it with a plasticizer and a two-component conditioning agent to adjust the amount according to the workers' on-site construction reactions.
