【Product Introduction】

Traditional toilet caisson backfill material generally adopts construction waste or ceramsite, and its disadvantage is that the cost is high, time-consuming, the bulk density is uneven (there is a dead angle), the foundation load is heavy, the anti-leakage effect is poor, the seismic resistance is poor, the repair is laborious, etc. Backfill treasure adopts a new foaming technology, a little foaming material and water in a short time to foam to 4-7 times the volume, and then uses the exclusive formula to stabilize the foam and enhance the waterproof treatment, the foamed concrete formed has the advantages of light weight, heat insulation, waterproof and seismic resistance, tensile resistance, high strength, and good filling density.

【Performance characteristics】

It is a new generation of high-efficiency, low-cost, and excellent performance of toilet backfill materials, which is in line with the national policy of energy conservation and emission reduction, and accelerates the pace of resource optimization, which will fully replace traditional backfill materials

【Backfill treasure construction process】

(1). Clear the debris to be backfilled, do a good job of waterproofing, store squatting toilets, toilets and sewage pipes, preliminarily fix, do a good job of waterproofing.

(2). Add 40KG of water in the special mixing barrel.

(3). Add 1 package of material A, stir at high speed, and foam to the designated position.

(4). Turn to low speed gear, add 1 bag of 50KGPC32.5 or PC42.5 cement mix at an average speed.

(5). After the cement is cast, add 1 package of B material, stir for about 1 minute, stop the machine (it can also not be stopped, so as to facilitate the smooth discharge))

(6). Move the mixing drum to the position to be backfilled, and open the valve to let the foamed slurry flow to the backfill part.

(7). The above process is repeated six times, that is, to complete a bathroom, volume backfill.

(8). Use a trowel or trowel to lightly press on the backfill surface and smooth it to form a flowing water slope.

(9). 24 hours later, the construction of the lower process of the base surface.

【Precautions】

1. The cement must be free of agglomerates and powder particles.

2. For each stirred slurry, the grouting time does not exceed 2.5 hours.

3. Do not use mineral cement such as "fly ash cement, slag cement, pozzolana cement"; It is best to use ordinary Portland cement and composite Portland cement.

4. 48 hours after the completion of construction, if there is no second construction, it is necessary to carry out sprinkling or soaking water every two days for curing.

5. When each cubic meter (6 times of mixing) is used for construction, it is necessary to check whether there is any residual cement residue at the bottom of the mixer barrel in time, and clean it up immediately if found, so as not to affect the foaming effect.

6. After the grouting is completed, the foamed cement needs to be stir-fried a few times, the surface of the bubbles that are too large are fully mixed, and then the surface is scraped flat. Do not stir-fry too much (about 3 times is fine).
