The fineness of the machine-made sand is about 2.5, and the powder content is 15%. Taking DPM10 as an example, the cement is 110kg, the additive is 5kg, the fly ash is about 20kg, and the rest is sand. The water requirement is 165kg, the consistency is 95, and the volume weight is 2000. The workers always reflect that the material is too sticky and quickly causes cracking. The fineness of the finished product is about 2.1, and the weight is 24-26. What is the reason?
Plastering mortar always presents too sticky and cracked.
