Epektibong paraan upang mapabuti ang lakas ng foam concrete

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 uri ng semento na may mataas na maaga at huli na lakas (tulad ng dual-fast Portland cement) maaaring naaangkop na bawasan ang proporsyon ng semento, and cement varieties with low late strength or low early strength should increase the cement proportion;

2. Strength grade of cement. Maaaring bawasan ng high-strength grade cement ang proportioning na halaga, at ang mababang-lakas na grado ng semento ay dapat tumaas ang proporsyon na halaga nito;

3. The quality of cement. For the new type of dry-process rotary kiln cement, ang proporsyon ay maaaring maayos na bawasan, 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 mababang density o mas mataas na mga kinakailangan sa lakas ay dapat tumaas ang ratio ng semento, mataas na densidad o mas mababang lakas kinakailangan ay maaaring mabawasan ang semento ratio;

5. The variety and activity of active micro-aggregates (mga halo). Ang paggamit ng high-activity micro-aggregates ay maaaring mabawasan ang proporsyon ng semento (tulad ng ultra-fine slag), habang ang paggamit ng mga low-activity micro-aggregates (tulad ng pangalawang fly ash) maaaring tumaas ang proporsyon ng 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, fly ash, mag-abo, steel slag, pulbos na bato, buhangin, atbp., 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.
