Anchor Grout Manufacturers In Kerala

"Anchor grout" is a specialized type of grout used to secure anchors (bolts, rods, or other embedded items) into concrete or masonry. It provides high strength, durability, and stability for load-bearing connections in construction and engineering applications. Here's a detailed breakdown:

  Anchor Grout: Overview

Definition: Anchor grout is a cementitious, epoxy, or polyester-based material used to fill the annular gap between an anchor (like a bolt or rod) and the hole it is placed in. It locks the anchor in place, ensuring it transfers load effectively into the base material.

  Types of Anchor Grout

1. Cementitious Anchor Grout

Base: Portland cement + additives

 Use: Non-structural to semi-structural applications

 Advantages:

 Economical

 Easy to use

 Non-shrinking if formulated properly

 Disadvantages:

 Lower tensile and bond strength than resin types

 Slower curing

 2. Epoxy Anchor Grout

Base: Two-component resin (epoxy + hardener)

 Use: Structural applications, heavy loads

 Advantages:

 Very high bond and compressive strength

 Excellent chemical resistance

 Can be used in damp conditions

 Disadvantages:

 More expensive

 Requires careful mixing and application

 3. Polyester or Vinylester Grout

Base: Resin-based (polyester or vinylester)

 Use: Medium to high load applications

 Advantages:

 Fast setting

 Good corrosion resistance

 Disadvantages:

 Lower heat resistance than epoxy

 May emit strong odors during curing

 Key Properties

Property Description

Compressive Strength Ranges from 30 to 100+ MPa depending on the type

Bond Strength Critical for load transfer between anchor and base

Flowability Important for ease of installation

Shrinkage Should be minimal or compensated

Setting Time Varies (minutes to hours)

Chemical Resistance Especially important in industrial or marine settings

 Applications

Anchoring machinery and equipment

 Fixing steel structures to concrete

 Bridge bearings

 Rebar and dowel bar installation

 Railings, signposts, and safety barriers

  Installation Steps (Typical)

Drill hole to specified depth and diameter.

 Clean hole thoroughly (brush + air blow).

 Mix grout as per manufacturer’s instructions.

 Place anchor (either before or after pouring grout, depending on method).

 Pour/inject grout into hole.

 Cure as per product data sheet.

  Best Practices

Use the right type of grout for the load and environment.

 Avoid air pockets while placing grout.

 Follow temperature and humidity guidelines during installation.

 Allow full curing before applying loads.
