Batimix Epoxy A-300

Description

BATIMIX Epoxy A-300 is a pure epoxy-based injection resin used for various repair and construction applications.

Main Purpose

BATIMIX Epoxy A-300 is versatile and therefore suitable for various fields of use, such as:

• Anchoring of rebars in repair jobs
• Fixing of steel dowels with various diameters and lengths
• Joint connections in various constructions such as box culverts, beams, and slabs

Features

BATIMIX Epoxy A-300 is characterized by its fast setting, reduced shrinkage, easiness to extrude, and extremely high strength capacity. It is suitable for use in damp conditions. It adheres very well to most construction materials and exhibits excellent resistance to chemicals.

Properties

• Density : 1.5 g/cm³
• Color : grey
• Hardener: black amina
• Ratio of the mix: 1:1
• Application temperature : from -5 to +40 ºC

Health and Safety

BATIMIX Epoxy A-300 is not a hazardous material. However, it should not be swallowed or allowed to come into contact with skin and eyes. Suitable gloves and goggles should be worn. For additional information, kindly refer to the product’s Material Safety Data Sheet.

Conformity with Standards

Fixing rebars with BATIMIX Epoxy A-300 complies to BAEL 91 specifications.

BAEL (Béton Armé aux États Limites) is a set of design and calculation rules used for reinforced concrete structures in France. BAEL 91 is a specific version of BAEL specifications that were published in 1991.

BAEL 91 specifications are used to design reinforced concrete structures in France and are widely used in the construction industry in France. The specifications include rules for designing reinforcement bars, calculating loads and stresses, and assessing the strength of materials.

The product conforms to the nroms NF P 18-831 and NF P 18-836.

Directions for Use

The general steps to be implemented when using BATIMIX Epoxy A-300 can be summarized as follows:

1-Drill the location to be repaired, and clean well 2-Inject BATIMIX Epoxy A-300 to the required depth 3-Insert the bar 4-Allow enough time to achieve full curing (refer to the table below)

Data for steel HA Fe E500. The working load is determined from the equation: L = β × (F / D), where L is the depth (mm), F is the maximum load possible on the bar (daN), D is the drill bit diameter, and β is a parameter linked to the quality of concrete. The β is taken equal to 1 or 1.51 for concrete having 20 to 25 MPa or 35 to 45 MPa, respectively.
