sodium lignosulfonate superplasticizer are surfactants. After they are added to concrete, the hydrophobic groups are directionally adsorbed on the surface of cement particles, so that the cement has a negative charge. The cement particles with the same charge are mutually repulsed and dispersed under the action of charge repulsion. The flocculent structure formed by the cement at the initial stage of adding water becomes a dispersed structure, and the free water in the flocculent condensate is released, so as to achieve the purpose of water reducing agent. Therefore, adding wood calcium superplasticizer into concrete can reduce the water consumption of concrete mixture, reduce water cement ratio, improve workability, facilitate pumping and improve the strength, compactness and durability of concrete

AMPS Fluid Loss Additive Risol FL2000S Overviews Risol FL2000S is a water-soluble synthetic polymer with strong dispersive properties in powder form,which can control fluid loss through Adsorption and aggregation reducing pore size and enhancing viscosity of water phase. FLAC Risol FL2000S is effective at temperatures higher than 400F (204C).The Product can help control fluid losses in seawater slurries, salt-saturated slurries, and slurries containing 5% KCl or 2% CaCl2. Risol FL2000S was developed as a less dispersive alternative to Halad-413 fluid-loss additive. It has a broad range of applications and has been developed to meet response requirements in heavyweight slurries, seawater, and saturated salt designs. It is designed for use in heavyweight (high-density), high-temperature slurries or any slurry that contains salt (2% up to saturated) with no loss of performance, it is the ideal fluid-loss additive for high-temperature, high-density slurries.

In the rotary klin calcining petroleum coke, the petroleum coke is calcined in a natural way, and the temperature is at about 1350.The lining material hall be of good thermal shock resistance, small changes in the lining line and excellent abrasion excellence. The castable produced by our company adopts dense brown corudum and mullite as the aggregate and fine powder, mixed with 97 sillicon carbide to increase the thermal shock resistance and abrasion resistance, and ensure small changes in the lining line. In the process of use, each castable plate is tightly bonded, without seams and castable peeling. And the petroleum coke is not sticky to the klin wall in the calcining process.
Csa binder is a hydraulic binder based on sulfo-aluminate cement, rather than calcium aluminates which are the basis of calcium aluminate cement (fondu cement) or calcium silicates which are the basis of portland cement. Csa binder is used in formulated products either as a hydraulic binder by itself or with the addition of calcium sulphates or in combination of portland cement. When used as an additive, the following properties can be developed, such as: fast setting time, rapid hardening, the early strength and final strength gains, lower alkalinity (ph value), good expansion value, cracking resistance, corrosion resistance, it can also worked in low temperature. Csa binder can be applied to a wide range of products: Fast setting cement and mortars Rapid repair mortars Fast set tile adhesives Self levelling compounds Self smoothing mortars Non-shrinkage grouts Water stopping mortars Glass fiber reinforced concrete (grc), etc.

We, Imperial World Trade Frequently Placed In Ordinary Portland Cement Mortar, Sometimes With A Little Extra Cement Or Some Fireclay Added To Make The Mixture Fireclay Mortar. A Refractory Composition Comprising Of Heat Resistant Binding System And Low Grain Size Refractory Furnaces. Mostly Used For Joining Bricks. Two Types Of Settings: Air And Heat Setting Mortar The Mortar Hardens At A Heat Above Room Temperature. The Problem With Using Regular Mortar Is That Portland Cement Can't Take The Heat. Curiously, Cement Retains Its Energy Up To Reasonably High Temperatures But Declines As It Cools Down Through About 600�° F. Ultimately All That Is Left Of The Mortar Is The Sand And Fireclay, With No Cement Binder. The Mortar Has No Strength And Easily Falls Out Of The Joints, Especially If They Are Wide. Refractory Mortar, On The Opposite Side, Is Performed With High-Temperature Cement And Carefully Selected Aggregates That Don't Expand And Tear The Mortar Apart When Heated. The International Residential Code (IRC) And International Building Code (IBC), Which Were Recently Adopted In Approximately All States And Require That Fireboxes, Smoke Chambers, And Flue Liners Be Laid With Refractory Mortar.
