the question about sharp sand for wet-mixed mortar

[Alex]

A wet-mixed mortar liquid plasticizer is easy to bleed when used with sharp sand, and the bubbles are lost quickly, making it difficult to maintain the state.
It is challenging to solve this problem when only considering plasticizers. The initial state can be adjusted to improve, but the loss is too fast, and the mortar will diverge.

It means the power content is negligible.

 

[Luis]

The powder content of washed sand is usually not high and it is too pure.

Add some fine padding.

 

[Allen]

Adding tailings can solve it, but I would like to know if there is any solution other than a plastic plasticizer since it is challenging to add a liquid one.

Admixtures are not a panacea.
Add something like thiourea to improve the pulp and see if it works.

Add some coal ash.
