| These values may vary depending on the characteristics of the raw materials and are not guaranteed. | |
| – consist of multi-component refractory aggregate in bags and liquid binder in canisters, – liquid binder – silica sol based on SiO2 nanoparticles of about 10 nm (0.01 μm), – concretes do not contain chemically bound water, the complete removal of water occurs at a temperature of less than 150 ° C, which allows to produce drying on a significantly accelerated mode with a rate of temperature rise of 50-100 ° C / hour, – when manufacturing products, heat treatment at 150°C (as opposed to 650°C for concrete containing cement) is sufficient for complete water removal, – drying of the lining or products can be started as soon as the concrete has hardened, the delay required for cement hydration is not necessary, – concretes practically do not contain CaO, so they have higher fire resistance compared to similar cement-bonded concretes, – thermal resistance (ability to resist temperature fluctuations) significantly exceeds the thermal resistance of concrete containing cement, – concretes have high adhesion to brick or monolithic lining, which makes them indispensable for repair works, including at high temperature of the repaired surface |
|
| DISADVANTAGES: – liquid binder should not be exposed to sub-zero temperatures, transport and store it at temperatures above 5°C, – concrete hardens slowly after placement, the strength of the raw material before drying is low, which can lead to problems during formwork removal and transportation of products that have not been heat-treated. |
