IS 3466: 1988 pertains to masonry cement. This standard delineates the manufacturing process, as well as the chemical and physical prerequisites of masonry cement, suitable for various general purposes requiring mortar in masonry work. Masonry cement, a specially blended type, is combined with sand and water in precise proportions to produce a robust binding mortar.

Masonry cement is manufactured by blending Portland cement clinker with either pozzolanic materials like fly ash and calcined clay pozzolana, or non-pozzolanic materials such as limestone, dolomitic limestone, conglomerates, dolomite, granulated slag, and waste materials like carbonated sludge and mine tailings. Gypsum and air-entraining plasticizer are added in suitable proportions to ensure the final product meets the standard requirements.

When subjected to the specified testing methods, masonry cement must adhere to the physical specifications outlined in the standard. It is the manufacturer's responsibility to verify that the cement meets the standards set by this regulation. An appropriately maintained laboratory is required for conducting the various tests in accordance with the specified methods.

TESTS

The specified tests must be conducted for MASONRY CEMENT IS 3466:1988

• Fineness

• Setting time

• Air content

• Water retention

• Soundness

• Compressive strength

• Staining

Packing of masonry cement must adhere to the guidelines specified in IS 3466:1988, while labeling and marking should also align with these standards. The BIS Standard Mark (ISI Mark) must be visible on each bag or drum of masonry cement, or on its label, provided the material meets the specified requirements. Manufacturers are required to obtain a BIS license from the Bureau of Indian Standards to use the standard mark (ISI Mark). This license is granted following a successful evaluation of manufacturing infrastructure, quality control, testing capabilities, and production processes.
