How Bos Concrete Is Combating the Challenges of Type 1L Cement for Better Results

As the concrete industry adjusts to the increased use of Type 1L cement—a cement blend with a lower carbon footprint—contractors and finishers across the country are facing new challenges. While more sustainable, Type 1L tends to set faster and hold less moisture at the surface, making it tougher to work with and finish properly.

At Bos Concrete, we recognize the issues our customers are facing and have taken proactive steps to ensure our ready-mix concrete remains consistent, reliable, and easier to finish—even in demanding conditions.

Solutions We’re Implementing for Better Performance

1. Enhanced Admixture Chemistry

We’re incorporating high-performance chemical admixtures that help control set times, retain moisture, and improve workability. These specialized additives are designed to address both the positive and negative ionic imbalances common in Type 1L blends, giving finishers more flexibility during placement and troweling.

2. Surface Moisture Control with Knox Crete and Day 1

To further improve surface conditions, we provide access to industry-leading finishing products:

• Knox Crete | Stage 1: A topical spray applied during the finishing process that helps maintain surface moisture longer, reducing premature drying and cracking.
• Day 1 Finishing Aid: Applied to the slab during troweling, this product extends finishing time, improves hydration, and reduces the risk of surface defects.

3. Access to Type 1/2 Cement Blends

Understanding that not every project benefits from Type 1L, Bos Concrete is also importing and offering Type 1/2 cement to our customers. This traditional blend provides more flexibility and consistency for contractors needing specific performance characteristics.

Bos Concrete is committed to more than just delivering concrete. We’re helping ensure our customers can place and finish it with confidence. By offering both advanced mix designs and tools to manage surface moisture, we’re staying ahead of industry changes and standing behind the contractors who count on us every day.
