ZL-SJ Epoxy Mortar

ZL-SJ Epoxy Mortar is a cement-based composite material modified with a waterborne epoxy resin system, and it also falls under the category of modified epoxy mortar products. It primarily consists of waterborne epoxy resin, curing agents, cement, mineral admixtures, crack-resistant fibers, and cement superplasticizers. The product comes in a three-component packaging system; at the construction site, the epoxy emulsion (Component A + Component B) is prepared according to the specified mix ratio, and then the dry powder (Component C) is added and mixed mechanically—this mixture can then be applied either by troweling or machine coating.

Product Description

Product Introduction

ZL-SJ Epoxy Mortar is a cement-based composite material modified with a waterborne epoxy resin system, and it also falls under the category of modified epoxy mortar products. It primarily consists of waterborne epoxy resin, curing agents, cement, mineral admixtures, crack-resistant fibers, and cement superplasticizers. The product comes in a three-component packaging; at the construction site, the epoxy emulsion (Component A + Component B) is prepared according to the specified mix ratio, and then the dry powder (Component C) is added and mixed mechanically—this mixture can then be applied either by troweling or machine coating.

ZL-SJ is a polymer-modified cement mortar specifically recommended for reinforcing critical structures, as outlined in GB 50367, the "Code for Design of Concrete Structure Strengthening." It meets the technical requirements for polymer-modified cement mortar Grade I used in structural reinforcement, as specified in GB 50728, the "Technical Specification for Safety Assessment of Engineering Structural Reinforcement Materials."

Product Advantages

1. High toughness, high strength, and high adhesion—resistant to impact and wear-resistant;

2. Exceptional durability, resistant to permeability, frost, water, salt, alkali, and weak acid corrosion;

3. Easy to apply and scrape, providing a smooth and flawless finish; offers excellent resistance to sagging, allowing for overhead application as well.

4. Fast curing, which can shorten the construction and maintenance periods;

5. Compared to oil-based epoxy mortar, it has lower costs and is easier to apply; additionally, all equipment and tools can be easily washed with water.

6. Contains no organic solvents, environmentally friendly and green, non-flammable and non-explosive, and harmless to humans.

Applicable Conditions

1. Prestressed steel wire mesh reinforcement construction for projects such as bridges, roads, hydraulic structures, railways, and building construction: - Surface repair of concrete structural defects, including erosion, spalling, exposed reinforcement, and honeycombing. - Protection and restoration of buildings and structures against abrasion, cavitation, freeze-thaw cycles, and carbonation. - Wear-resistant protection and repair for critical areas in highways, bridges, airport runways, workshops, and other infrastructure projects. - Protective and repair solutions against acid, alkali, and salt corrosion in corrosive environments such as seawater, saline-alkali regions, oil refineries, chemical plants, factories, and port facilities.

2. Surface defects in concrete structures, erosion, spalling exposing reinforcement bars, and honeycombing—these are repaired by applying a skim coat.

3. Repair and protection against acid, alkali, and salt corrosion;

4. Prestressed steel wire mesh reinforcement construction;

5. Bridge protection and repair against cavitation, freeze-thaw cycles, and carbonation.
