MABNA P-N-15 Normal Concrete Superplasticizer

Product Introduction

Currently, concrete admixtures have secured a strong position in the concrete industry due to their simultaneous effects on several properties of fresh and hardened concrete. According to international and national standards, a superplasticizer/high-range water reducer is defined as a material that significantly reduces the mixing water content without changing workability, or significantly increases slump or flowability without changing the water content, or provides both effects at the same time.
MABNA P-N-15 is a fourth-generation high-performance concrete superplasticizer based on polycarboxylate ether, produced by the Polycarboxylate Resin R&D Unit of Alvand Chemical Yaran Company. This product has been developed to produce concrete with a low water-to-cement ratio and high workability, and it also shows excellent performance in the production of self-compacting concrete (SCC).

The properties of MABNA P-N-15 normal superplasticizer in concrete include improved workability, adjustment of workability retention time according to execution requirements, enhanced concrete compaction, reduced concrete permeability through lowering the water-to-cement ratio, increased durability, and improved mechanical strength. Achieving high strength and durability with a moderate dosage is another advantage of this product. Due to its polycarboxylate chemical base, it is suitable for producing various special concretes, high-strength concretes, concretes with high pumpability, and for concreting in all structural elements such as slabs, foundations, walls, and piles. This product performs well with all types of cement and pozzolans, and the presence of clay in aggregates does not affect its initial workability or workability retention.

Based on the mentioned characteristics, the use of MABNA P-N-15 normal superplasticizer is possible under all climatic conditions. The optimal dosage depends on factors such as cement type, environmental conditions, and project requirements, and should be determined through laboratory or on-site testing.

Advantages

• Significant water and water-to-cement ratio reduction: up to 25% reduction in mixing water
• Increased workability and slump retention: production of high-slump concrete even at low water-to-cement ratios and extended workability time
• Improved mechanical properties and durability: increased compressive strength at early and later ages, improved abrasion resistance, and enhanced resistance to freeze–thaw cycles
• Reduced permeability and improved watertightness: lower permeability against chloride ions, sulfates, and water due to reduced water-to-cement ratio
• Improved cohesion and integrity: production of cohesive concrete without segregation and reduced creep and shrinkage
• Ease of application: improved pumpability and reduced equipment wear
• Wide compatibility: compatible with all types of Portland cement and pozzolanic materials without altering setting time
• Economic efficiency: possibility of reducing cement consumption by up to 15% without strength loss
• Safety and environmental compatibility: free of chlorides and other harmful ions for steel and concrete; non-toxic and non-flammable

Applications

• Execution of various structural elements such as piles, foundations, columns, walls, and slabs with uniform compaction and high surface quality
• Production and placement of prestressed and precast concretes with excellent workability and minimal air entrainment
• Improved effectiveness of cement grout injections such as for nailing grout, shotcrete, and soil stabilization operations by enhancing penetration and adhesion
• Construction of watertight structures and low-permeability concretes for reservoirs, canals, and projects in direct contact with surface and groundwater
• High compatibility with pozzolans and blended cements to enhance mechanical properties and concrete durability
• Production of self-compacting concrete (SCC) and exposed concretes with uniform, void-free surfaces and desirable visual appearance
• Increased concrete flowability while maintaining cohesion, preventing segregation, and ensuring high adhesion during placement
• Reduction of water-to-cement ratio while maintaining high slump, resulting in high compressive strength at early and final ages
• Faster concreting and formwork removal, reduced execution time, and overall cost savings
• Improved concrete durability in harsh environments through reduced chloride and sulfate penetration, increased abrasion resistance, and enhanced resistance to freeze–thaw cycles
