Applicable Industries

High alumina cement feature covering metallurgy, chemical industry, building materials, electric power, military industry, nonferrous metals, carbon industry and other high-temperature, super high temperature kiln and equipment refractory materials use requirements, products throughout the domestic market, and exported to Korea, India, Brazil, Jordan and other international markets, wide user praise.

High Alumina Cement Feature

1. Early strength characteristics: its early strength improvement rate is much higher than that of fast hardening Portland cement, which is suitable for emergency repair projects, but the late strength will be reduced, so it is limited to use in structural engineering.

2. Hydration heat large, and concentrated in the early release: suitable for winter construction, can not be used in mass concrete works and high temperature humid environment of the project. Because of several kinds of exothermic, suitable for low temperature curing concrete works.

3. Strong resistance to sulfate: in the hydration process, free calcium hydroxide is not separated out, but aluminum hydroxide gel is formed, and a protective film is formed on the particle surface. The resistance to erosion was reduced during the later crystal transformation. Therefore, it is suitable for engineering with the requirement of resisting sulfate erosion.

4. High temperature resistance: high alumina cement can be used as the cementing material of the heat resistant concrete, configured into the heat resistant concrete.

5. Good heat resistance: because of the high temperature of the production of solid reaction, sintering bonding instead of hydration, so that high aluminum cement at high temperature can still maintain a high strength.

The configuration and use of this series of castable is basically the same as that of heavy refractory castable, the difference is that its aggregate bulk density is small, easy to absorb water. Therefore, the use of dry materials should be mixed well, add half of the proportion of water to mix first, wet mix evenly, in the other half of the water and cement binder poured as even mixing after use. The temperature is not the same as the use of cement binder is not the same, after pouring mold curing 3-5 days, after oven normal use, generally used in the insulation layer.

Insulating castable manufacturing is a kind of unshaped refractory castable. Lightweight heat resistant castable in the preparation, the main choice of fire-resistant lightweight aggregate and powder, in the selection of the corresponding binder and admixture from the preparation. The only difference between the properties of lightweight castable and heavy castable is that the test of softening temperature under load is 0.1 mpa.

It will generally choose to do the industrial kiln construction of the heat insulation layer, its reason is that the insulating castable manufacturing low refractory, general use temperature of 600~900℃, more suitable for the boiler construction below 1000℃.

Different from traditional refractory castable, the ultrafine powder with the same or similar chemical composition with the main material of castable is used to replace part or most of calcium aluminate cement in the substrate of low-cement refractory castable.

Low cement castable has many advantages, among which low CaO content can reduce the formation of low eutectic phase in the material, thus improving the refractoriness, high temperature strength and slag erosion resistance. We are the high quality cement castable supplier, the product variety is complete, welcome to consult and buy.

The mixed water consumption of this series of refractory cement castable during construction is only 1/3~1/2 of that of ordinary castable, so the porosity is low and the volume density is high. After it is poured into shape, the cement compounds generated in the curing are less, there is not a large number of hydration bond destruction during heating and baking, which leads to the decrease in the temperature strength, but with the increase of heat treatment temperature, the strength is also gradually increased. With proper adjustment of the strength composition of the low cement castable, the artesian castable and the pump castable can be prepared. We produce low – cement castable widely used, stable and reliable quality, reasonable price.
