Embodiment 1
[0023] An energy-saving mortar comprises the following raw materials in parts by weight: 40 parts of cement, 26 parts of medium sand, 19 parts of yellow sand, 10 parts of limestone, 15 parts of modified admixture, 12 parts of water-retaining thickener and 26 parts of water.
[0024] The modified admixture is hydroxypropyl methyl cellulose ether, which is low in cost, has a wide range of material sources, and has a good modification effect.
[0025] The water-retaining thickener is polyacrylamide, which is beneficial to improve the viscosity of the mortar and ensure that the drying and solidification of the mortar is slowed down when it is not in use.
[0026] A method for preparing energy-saving mortar, comprising the following steps:
[0027] Step 1. Put limestone, medium sand and yellow sand into the pulverizer for crushing, and then use three layers of screens to screen to obtain fine sand. The number of screens in the screens is 100, 150, and 200 respectively;

Embodiment 2
[0033] An energy-saving mortar comprises the following raw materials in parts by weight: 30 parts of cement, 20 parts of medium sand, 13 parts of yellow sand, 10 parts of limestone, 15 parts of modified admixture, 12 parts of water-retaining thickener and 20 parts of water.
[0034] The modified admixture is a combination of hydroxypropyl methylcellulose ether and redispersible latex powder, which is low in cost, has a wide range of material sources, and has a good modification effect.
[0035] The water-retaining thickener is polyacrylamide, which is beneficial to improve the viscosity of the mortar and ensure that the drying and solidification of the mortar is slowed down when it is not in use.
[0036] A method for preparing energy-saving mortar, comprising the following steps:
[0037] Step 1. Put limestone, medium sand and yellow sand into the pulverizer for crushing, and then use three layers of screens to screen to obtain fine sand. The number of screens in the screens ...
Embodiment 3
[0043] An energy-saving mortar comprises the following raw materials in parts by weight: 36 parts of cement, 23 parts of medium sand, 18 parts of yellow sand, 8 parts of limestone, 13 parts of modified admixture, 12 parts of water-retaining thickener and 24 parts of water.
[0044] The modified admixture is redispersible latex powder, which is low in cost, has a wide range of material sources, and has a good modification effect.
[0045] The water-retaining thickener is polyacrylamide, which is beneficial to improve the viscosity of the mortar and ensure that the drying and solidification of the mortar is slowed down when it is not in use.
[0046] A method for preparing energy-saving mortar, comprising the following steps:
[0047] Step 1. Put limestone, medium sand and yellow sand into the pulverizer for crushing, and then use three layers of screens to screen to obtain fine sand. The number of screens in the screens is 100, 150, and 200 respectively;
[0048] Step 2. Mix f...
