Yes, GAYREX® Mortar is suitable for bedding and joint filling in RCC chimneys, offering resistance to acidic and high-temperature corrosive gases.
The typical mixing ratio is one part liquid sodium silicate solution to 2.5 to 3 parts powder filler by weight, mixed thoroughly to achieve workable consistency.
Yes, GAYREX® Mortar provides resistance to acids, acidic salts, alkalis, and other corrosive substances including mineral oils and alcohols.
Working time is approximately 20-25 minutes at 27±2°C. Lower temperatures may extend setting time, but it should not be applied below 10°C.
Yes, in less severe conditions it is commonly used as a bedding material; however, for severe corrosive environments, it is recommended for both bedding and jointing.

GAYREX® - is a sodium Silicate base cement was developed to solve corrosion problem involving oxidizing acids. It is the only cement that will resist high temperatures and highly concentrated solutions. It resists acids, acidic salts, alcohols, grease, fats, mineral oils & alkalis. GAYREX® - K Mortar will resist a temperature up to 8000CUseAcid Resisting Bricks / Tiles Lining based on GAYREX® - Silicate Resin Mortar is recommended for severe corrosive conditions as in reaction vessels, storage tanks, neutralization pits, drains, floors and other areas.GAYREX® - Silicate Mortar is used in different industries like Steel, Dyestuff, Metal Finishing, Thermal Power Plants, Fertilizers, Petrochemicals, Food processing, Beverages, Breweries, Dairies etc.For severe corrosive conditions GAYREX® - Silicate Mortar is used for bedding and jointing of tile / bricks and for less severe conditions, it is used as a Bedding Materials most the time And in some cases like RCC Chimney, it is Used as Bedding – Joint Filling Mortars.PropertiesPROPERTY: Require as per IS 4832 Part 1 GAL ResultsWorking time min, @ 27 0C +- 2 0C: 20 : 25Compressive Strength, min kg/cm2 (@ 7days): 150: 165Bond Strength, min kg/cm2 (@ 15days): 5: 5Flexural Strength, min kg/cm2 (@ 7days): 40: 45Absorption of Toluene, Max% by weight: 18: 15Directions for Use(1) The material is supplied two parts generally mixing at site in small usable lots in recommended. The resin is first taken in weighed quantity and the power filler is slowly mixed in it while stirring with trowel till a working consistency is obtained. This is approximately one part Liquid Solution is 2.5 to 3 parts power. Since the applicability for joints and bedding varies, the vertical joints may need more and workable mortar. Temp. not less than 10o C.(2) Butter the brick/tile with prepared mortar and slide them in place, then tap them firm Engineered for international industrial buyers, this refractory mortar ensures durability, performance, and export compliance.
