The invention provides a mechanical spraying plastering mortar and an additive. The mechanical spraying plastering mortar comprises: by weight, cement 10%-18%, fly ash 5%-10%, sand 75%-80%, and additive 0.5%. The additive comprises, by weight, cellulose ether 0.02%, montmorillonite powder 0.01%, starch ether 0.01%, water reducing agent 0.05%, air-entraining agent 0.0035%, and wood fibre 0.1%. The product optimizes the mix ratio of the plastering mortar, and mixes a certain ratio of additive, so that the plastering mortar has sag resistance, good lubricity, water-retaining property and fluidity, and strong binding power, and the performance requirements of mechanical pumping and spraying construction of the plastering mortar is realized. And thus, labor intensity is reduced, construction efficiency is enhanced, and the construction efficiency is more than two times of that of manual plastering. The wall plastering using mechanical spraying construction has high pressure and is uniform, avoids empty drum and crack of the plaster layer, and improves the engineering quality of the additive.
