Con-Lub SP
High-Performance Superplasticizer for Stronger Concrete
Better Workability. Higher Strength. Superior Concrete Performance.
Product Description
What is Con-Lub SP?
Con-Lub SP is a high-performance PCE-based Superplasticizer Concrete Admixture developed by Baral Chemical Company Ltd. It is specially formulated to improve concrete flowability and workability while reducing the amount of mixing water required.
Con-Lub SP helps achieve better compaction and denser concrete, reducing the risk of honeycombing, voids, and poor consolidation. Its water-reducing performance also supports improved early and ultimate strength, better bonding, and enhanced durability of concrete structures.
It is particularly suitable for Ready-Mix Concrete, Precast Concrete, Pumped Concrete, Bridges, Culverts, High-Rise Buildings, and other demanding structural applications.

Application Process
Simple Steps for Better Concrete Flow
Con-Lub SP helps improve concrete flowability and workability while reducing the need for excess mixing water. Follow the proper mixing and placement process for consistent performance.
01
Prepare the Concrete Mix
Prepare the concrete according to the required mix design using the correct proportions of cement, sand, aggregate and water.
02
Add Con-Lub SP
Add the recommended quantity of Con-Lub SP to the concrete mix. For general site guidance, approximately 350 ml per bag of cement may be used.
03
Mix Thoroughly
Mix properly so the admixture is distributed evenly throughout the concrete. Uniform mixing helps maintain consistent flowability and workability.
04
Place & Compact
Place or pump the concrete as required and compact it properly. Better flow helps concrete move around reinforcement and can reduce honeycombing.
Important: Actual dosage may vary depending on cement type, mix design, required slump and site condition. A trial mix and technical guidance are recommended for important projects.

Con-Lub SP FAQs
Simple answers to common questions about Con-Lub SP, water reduction, concrete flowability, dosage and applications.
Con-Lub SP is a high-performance water-reducing
plasticizer from Baral Chemical Company Ltd. It helps improve concrete flowability and workability
while reducing the need for excess mixing water.
Con-Lub SP helps improve concrete flowability,
reduce excess water, support better compaction
and make concrete easier to place. Proper use can
also help minimize honeycombing and support improved
concrete strength.
Con-Lub SP can be used in ready-mix concrete,
precast concrete, pumped concrete, high-rise buildings,
bridges, culverts, dams and other structural
concrete applications.
A general site guideline is approximately 350 ml per bag of cement.
However, actual dosage can vary according to cement type,
mix design, required workability and site condition.
Yes. Con-Lub SP is designed to help reduce the amount
of mixing water while maintaining good concrete
flowability and workability. This can support a lower
water-cement ratio when the mix is properly designed.
By helping reduce unnecessary mixing water and supporting
better compaction, Con-Lub SP can contribute to improved
early and ultimate concrete strength when proper mix design,
placement and curing practices are followed.
Baral Chemical Company Ltd. provides
concrete admixture solutions and technical guidance for
residential, commercial and infrastructure projects.
For customers looking for a reliable construction chemical
supplier or the best chemical company in Bangladesh,
Baral Chemical provides professional product and
project-specific support.
Con-Lub SP is white in colour; liquid is paste like mass, depending on temperature. It is soluble in water. It is used in Reinforced Cement-Concrete, Cement-Concrete and plastering, etc. in a word, for all kind of concrete. Con-Lub SP is linear polymerize between cross-linked small lumps in the concrete masses. It also reduces water-cement ratio remarkably, procuring satisfactorily high work-abilities and strength of concrete.
