Epektibo nga paagi sa pagpalambo sa kalig-on sa foam kongkreto

With the widespread application of foam concrete, the strength issue has also become an important issue restricting the development of foam concrete.

We should improve the strength of foam concrete from the following aspects:

1. The variety of cement. Mga tipo sa semento nga adunay taas nga kusog sa sayo ug ulahi (sama sa dual-fast nga semento sa Portland) makapakunhod sa gidaghanon sa semento, and cement varieties with low late strength or low early strength should increase the cement proportion;

2. Strength grade of cement. Ang high-strength grade nga semento makapakunhod sa gidaghanon sa proporsiyon, ug ang ubos nga kalig-on nga grado nga semento kinahanglan nga magdugang sa gidaghanon sa proporsiyon niini;

3. The quality of cement. For the new type of dry-process rotary kiln cement, ang proporsiyon mahimong tukma nga pagkunhod, while the proportion of vertical kiln cement or cement with a large amount of mixed materials should be appropriately increased;

4. The density and strength requirements of the product. Ang ubos nga densidad o mas taas nga mga kinahanglanon sa kusog kinahanglan nga magpataas sa ratio sa semento, ang taas nga densidad o ubos nga mga kinahanglanon sa kusog makapakunhod sa ratio sa semento;

5. The variety and activity of active micro-aggregates (mga sagol). Ang paggamit sa high-activity micro-aggregates makapakunhod sa proporsiyon sa semento (sama sa ultra-fine slag), samtang ang paggamit sa ubos nga kalihokan nga micro-aggregates (sama sa secondary fly ash) makadugang sa proporsiyon sa semento;

6. Add appropriate admixtures, such as foam concrete enhancers.

Aiming at the strength of foam concrete, foam concrete enhancers, self-insulating block enhancers, foamed cement insulation board enhancers, lightweight partition board enhancers have been developed for the strength of foam concrete. The enhancers made by nano-modification technology have the following significant features:

1. It has good workability with industrial wastes such as cement, langaw nga abo, slag, steel slag, stone powder, balas, ug uban pa., and can make cement products set early, shape early, demould early, exert strength early and put into use;

2. It can improve the plasticity of cement, speed up the turnaround time of equipment utilization and increase labor productivity, and significantly increase the 3d, 7d early strength and 28d late strength of cement products;

3. The addition amount is small, the performance is excellent, and the production cost is saved. The addition amount is 2-3kg per cubic meter;

4. It can improve the rheology of cement, improve the performance of cement, and can obviously improve the compressive and flexural properties of cement products;

5. The chemical performance is stable, the dosage is not sensitive, the thickening curve shape is good, and it can be used with other additives;

6. It has no adverse effects on other properties of cement slurry, and does not destroy the formation and development of cement strength;

7. It has a wide range of applications and can be applied to a variety of grades of cement.
