Grouts for Filling of Joints of Tiles and Stones — IS 17190 (2020) Testing

IS 17190:2020 testing is performed to evaluate the performance and suitability of grouts used for filling joints between tiles, stones and mosaics. It helps determine whether the grout meets specified requirements for strength, durability, water absorption, shrinkage and other relevant performance characteristics.

The standard evaluates important properties such as flexural and compressive strength, water absorption, linear shrinkage, abrasion resistance and transverse deformation. Depending on the grout category and applicable requirements, chemical resistance and other performance characteristics may also be assessed.

Yes. IS 17190:2020 covers grouts intended for filling joints of tiles, stones and mosaics used in internal and external floor and wall applications. The applicable performance requirements can vary according to the type and intended use of the grout.

CG1 and CG2 refer to classifications of cementitious grout covered by IS 17190:2020. These classifications are used to distinguish grout performance based on the requirements specified in the standard, allowing products to be evaluated according to their intended performance characteristics.

Reaction resin grout is one of the grout categories addressed by IS 17190:2020. The standard identifies classifications such as RG1 and RG2 and provides applicable performance requirements and test methods for evaluating these resin-based joint-filling materials.

Certko provides product testing support for IS 17190:2020 through laboratory testing of applicable grout properties. Its testing assistance can help businesses evaluate product performance, obtain test reports and support documentation required for quality and conformity assessment.

Cementitious grouts are assessed against the applicable requirements of IS 17190:2020 to determine properties such as flexural strength, compressive strength, water absorption, linear shrinkage and abrasion resistance. The specific tests depend on the classification and declared characteristics of the product.

Water absorption testing helps evaluate how much water a grout can absorb after exposure under the specified test conditions. This property is important because excessive water absorption can affect the durability and performance of grout used in tile and stone joints, particularly in moisture-prone applications.
