Bentonite is a high swelling clay mineral whose name was derived from the location of the first commercial deposits mined at fort benton, wyoming u. S. A. Mineralogically, bentonite mainly consists of montmorillonite in combination with various mineral impurities such as feldspars, calcite, silica, etc. Montmorillonite belongs to the smectite group of clays which also include similar behaving minerals such as beidellite, saponite and hectorite. Geologically bentonites are mainly of volcanic origin, the majority of commercial deposits were formed by the hydrolysis or metamorphism of volcanic rock or ash and are almostly found in everywhere in world. The structure of montmorillonite is fundamentally a three layer structure with an octahedral aluminium hydroxyl sheet sandwiched between two layers of silicon- oxygen tetrahedra. However, the aluminium atoms are partially replaced by the substitution of either magnesium or iron atoms, thereby creating a charge deficiency within the unit structure. This results in a small negative charge on the basal plane of silica tetrahedra which is balanced by absorption of exchangeable cations between adjacent platelets. In natural montmorillonite, these cations are usually calcium, sodium or magnesium according to the formations of bentonite. Specification -welldry activated clay (montmorillonite clay, bentonite clay), 100% pure clay desiccant without any calcium chloride. In p.P.

Uses SM-P is recommended strongly for use in all ready-mix, precast, and prestress concrete applications where low water-cement ratio, low permeability, high durability, high strength concrete is specified or high slump flowable concrete is required. SM-P can be applied in various concrete, including high strength concrete, high fluidity concrete, high duration concrete, aluminate cement refractory concrete, grouting material, steam curing concrete, high strength mortar, gypsum products, and so on. Advantages Increase concrete early strength. Promote workability. Increase flowability. Increase cohesiveness and segregation resistance. Shorten mold take-off time. Keep water/cement to a minimum. Promote air stability. Compatible with cements, gypsums and other admixtures. Reduce bleeding at high slumps. Woven fabric bag with plastic liner. Net weight: 20kg +/- 0.13 kg It is easy to absorb moisture from air. So it must be kept in original sealed bag and stored at dry condition. The shelf life is one year. This product is non-toxic and non-flammable. So there is no special transportation requirement.

HCSA binder is a hydraulic binder based on calcium sulphoaluminate, rather than calcium aluminates which are the basis of calcium aluminate cement or calcium silicates which are the basis of portland cement. The difference gives hcsa binder properties particularly suited to formulators of products such as self-leveling or self-smoothing compounds, rapid hardening screeds, tile adhesives, non-shrink grouts, rapid setting and special mortars. Hcsa binder is used in formulated products either as a hydraulic binder by itself or with the addition of calcium sulphates, or in combination with portland cement. The setting time is quicker than that of portland cement, and it also has a rapid strength development. Hcsa binder does not release free lime during hydration thus eliminates the major cause of efflorescence.
This product is an inorganic rigid waterproofing material which based on the special sulphoaluminate cement, and matching the suitable type and quantity admixture.
Polar bear non-shrink grouting material is blended through a special procedure by specially selected cementations material, carefully selected fine aggregate and admixture. It owns the characteristics of high flow, non-shrinkage, early strength and high strength. Functionally they are divided into two categories include four products: high strength, extra early strength.

HPMC For Construction HPMC for construction is a non-ionic cellulose ether obtained by alkalization, etherification, neutralization and washing of cellulose.HPMC powder has good properties of thickening, dispersing, emulsifying and film-forming, and it is the first choice for the production of high-quality building material additives. The use of hydroxypropyl methyl cellulose in construction In construction, putty powder is used in very large quantities. About 90% of HPMC in construction is used as putty powder additives, and the rest is cement mortar and glue, used as thickening and water retention agents. The amount of HPMC chemicals CAS9004-65-3 added to construction materials is very low, only 0.1%-1%, but it plays an irreplaceable role, which can significantly improve the water retention, fluidity and lubricity of construction materials. Building materials with added HPMC cellulose are easier to mix and use, improving the efficiency of construction workers, extending open time, improving bond strength, and forming a smooth and delicate surface coating. - Construction HPMC powders are used in cementitious mortars and grouts to improve ease of use, adhesion and water retention. - Hydroxypropyl methyl cellulose is also used in self-leveling compounds, tile adhesives and grouts to improve flow and workability. -Construction HPMC is commonly used as a binder and thickener in coatings and paints. - HPMC binders are also used in gypsum-based materials such as wallboard and ceiling tiles to improve workability and reduce water absorption.
