preparation example Construction
[0026] The preparation method of high-strength ground dry powder mortar, described method comprises the following steps:
[0027] Step 1: Screening the cement; specifically, the screening of the cement includes: screening the cement with a screening device;
[0028] The screening device such as Figure 1-3 As shown, it includes a lower hopper 1, and the lower hopper 1 is inserted into the inside of the screening box 4; the bottom end of the lower hopper 1 is rotatably connected with a lower material tube 3, and the lower material tube 3 adopts an inclined Structure; Specifically, a chute 11 is provided on the side of the hopper 1, and the inner slide of the chute 11 is connected to the slider 32; the slider 32 is fixed on the side of the feeding pipe 3; the The side portion of the feeding pipe 3 is fixed with a plate tooth 31, and the plate tooth 31 is connected to the rotary drive 2; the rotary drive 2 includes a motor 21, a rotating shaft 22 and a gear 23, and the plate too...
Embodiment
[0041] 1. Use the screening device to screen the cement;
[0042] 2. Weigh respectively according to the mass ratio of cement, sand and thickened powder as 23:76:1; specifically, weigh 2.3kg of cement, 7.6kg of sand, and 0.1kg of thickened powder;
[0043] 3. Mix the weighed cement, sand and thickened powder for 30 minutes to form dry powder mortar;
[0044] 4. Add 138ml of water to the above 10kg mortar and stir for 40 minutes.
[0045] Case 1: Select the above-mentioned stirred slurry and divide it into two groups. The average consistency of the two groups is detected to be 57mm, the average consistency after 2 hours is 50mm, and the consistency loss rate in two hours is 12.29%. The specific detection is shown in the following table (1) Shown:
[0046] Table (1) Dry powder mortar consistency test table
[0047]
Embodiment 2
[0048] Implement 2, get above-mentioned cement and carry out the detection of setting time, specifically as shown in table 2:
[0049] Table (2) is the test table of cement setting time
