MARBOS NL-330
High-range AE water reducing admixture

Introduction

MARBOS NL-330 is a chemical admixture for concrete mainly composed of modified lignin sulfonic acid compound and special polycarboxylic acids. It improves water reduction rate and slump maintenance compared to the conventional high-range AE water reducing agent. Excellent water reduction effect shorten setting time, improve early strength, workability, and freeze-thaw resistance. Overall, the product effectively enhances durability and quality of concrete. Special polycarboxylic acid polymer improves the water retention property of the chemical admixture and reduces the effects of drying shrinkage.

Properties

1. Appearance: dark brown liquid
2. Specific gravity: 1.15 ± 0.05 (20°C)(depending on site)
3. pH : 8±2

Characteristics

1. Produce high-flow concrete with significant unit water content reduction
2. Improve workability and reduce bleeding
3. Reduce hydration heat by decreasing amount of cement used
4. Reduce drying shrinkage with excellent moisture retention
5. Achieve excellent early strength by reducing early setting time in winter

Usage

1. General construction, civil engineering structure
2. Dam, road, runway construction
3. high-strength concrete

Amount of usage

1. In general, 0.5~2.0% of the cement used
2. Optimal amount is determined by on-site mixing test

Packaging

200kg drum/tank lorry

Precautions

1. Although it is not toxic or flammable, skin contact should be avoided.
2. In case of skin and eye contact, wash with clean water
3. If the product is frozen, thaw and check the performance before use.
4. If the product is intended to be used for the concrete items produced by steam curing, please contact our technical sales department before use.
