Product Description
The BA115 concrete superplasticizer is designed for concreting at very hot temperatures or long transportation. This concrete superplasticizer is able to maintain the workability of concrete for a long time and prevent the occurrence of cold joints in discontinuous concreting. In addition, it is suitable for use in strong concrete that requires high strength and good performance, this concrete superplasticizer is chlorine-free and is produced in accordance with ASTM C-494 Type B, D, G, Iranian National Standard No. 2930 and other international standards and is compatible with all types of cement. Obviously, due to the diversity of cement and aggregate characteristics in each project, preliminary tests are necessary.
Performance
Conventional superplasticizers, which are generally based on melamine formaldehyde or naphthalene sulfonate, are absorbed by cement particles during mixing, and in the initial moments of cement dewatering, this group of polymers increases the negative charge of cement particles and causes them to disperse.
Concrete superplasticizer BA115 differs from conventional superplasticizers in practice, as the base of this product is polycarboxylic ether and has molecular side chains. At the beginning of water absorption, it disperses cement particles well by increasing static electricity, like conventional superplasticizers. Subsequently, the presence of side chains greatly prevents the re-aggregation of cement particles and keeps them separate and dispersed. This behavior creates fluid concrete even at very low water levels.
Applications
The excellent cement dispersing property of BA115 has made it an ideal additive for producing strong concrete, especially in designs where the water to cement ratio is very low. This product can be used to produce fluid concrete that is easily moldable and fills all mold points without the need for vibration and is free of large bubbles.
Compatibility
In addition to the effects of this additive on fresh concrete, which are quite noticeable during the construction and pouring of concrete, it also has a favorable effect on hardened concrete. These include: increased long-term compressive strength, increased flexural strength, improved modulus of elasticity, improved adhesion to reinforcement and steel, better resistance to carbonation, lower permeability, better stability against environmental damage, reduced shrinkage and creep, and greater durability.
Appearance
Appearance of a flowing liquid
Color: Brown
Alkali number: 5-6
Specific gravity: 1.04 to 1.06 g/cm3 at 20°C
Compatibility
This superplasticizer for concrete should not be mixed with any other additives unless approved by Behsazan Company specialists. If multiple additives are required, each should be added separately to the concrete mixture. This additive is suitable for concrete mixtures containing microsilica, fly ash, and blended and pozzolanic cements.
Usage Amounts
The typical usage of BA115 concrete superplasticizer is between 0.3 and 0.8 percent of the weight of cement (total cementitious materials). Amounts outside this range are permitted subject to field tests.
Usage Guidelines
Packaging and Storage
BA115 is supplied in 20 liter cans and 220 and 1100 kg barrels or large tankers.
BA115 should be stored in its original container at a temperature above +5°C, away from direct sunlight and in a covered area. If it freezes, it can be gently warmed and stirred to be recycled. Improper storage conditions may damage the product or its container.
For information on proper storage methods, contact Behsazan Company’s technical department.
