MAPEI’s solutions enable users to work smarter, not harder – delivering stronger, more durable concrete with greater efficiency.

As construction materials evolve, contractors increasingly turn to advanced solutions that improve efficiency, performance and sustainability. MAPEI’s line of admixtures offers a smarter way to overcome the limitations of newly introduced Type 1L cement.
The challenges of Type 1L cement
Type 1L cement, also known as Portland-limestone cement (PLC), contains up to 15% interground free limestone – an increase from the 5% allowed in traditional Type 1 cement. While this change aims to reduce environmental impact, industry professionals have reported challenges such as:
- Increased water demand.
- Reduced workability.
- Shortened slump life.
- Lower early and late-age strengths.
- Reduced bleed water.
- Decreased finishability.
MAPEI’s solutions: Work smarter, not harder
MAPEI offers a range of admixtures that help contractors achieve optimal concrete performance despite the challenges of Type 1L cement:
- Re-Con AGG 100: Used at low dosage rates, it minimizes water absorption by the limestone, increasing the probability of bleed water, reducing surface cracks and enabling easier hard-trowel finishes. (Meets ASTM C494, Type B)
- Dynamon EW 12: This acrylic-based slump extender is designed to maintain concrete slump for up to 90 minutes and is ideal for use with low- to moderate-absorbing Type 1L cements. (Meets ASTM C494, Type S)
- Dynamon EW 100: This acrylic-based slump extender maintains slump for up to 90 minutes, optimized for moderate- to high-absorbing Type 1L cements. (Meets ASTM C494, Type S)
- Dynamon Easy 75: A blended acrylic-based admixture with MAPEI polycarboxylate polymers, it provides superior water reduction and extended slump life for improved finishing. (Meets ASTM C494, Type A and Type F)
- Mapecube line: These strength-enhancing admixtures reduce cement usage while maintaining compressive strength, supporting low-carbon concrete production:
- Mapecube 1: For precast concrete (Meets ASTM C494, Type S)
- Mapecube 4: For ready-mixed concrete (Meets ASTM C494, Type S)
- Mapecube 60: Strength enhancer with water reduction (Meets ASTM C494, Type A)
- Mapecube 60W: Cold-weather strength enhancer with water reduction and higher early strengths (Meets ASTM C494, Type A)
MAPEI’s solution: Dynamon Easy 75
MAPEI’s newest solution to address these challenges, Dynamon Easy 75, is a blended acrylic-based admixture that incorporates advanced polycarboxylate polymers. This innovative formulation is designed to enhance the performance of concrete mixes, offering several key benefits:
- Superior water reduction: Reduces the water-to-cement ratio without sacrificing workability, resulting in stronger, more durable concrete.
- Extended slump life: Maintains slump consistency for longer periods, improving workability and ease of placement.
- Enhanced finishability: Provides smoother and more consistent finishes, reducing the need for excessive labor during finishing.
- Versatility and compliance: Meets ASTM C494 standards for both Type A (water-reducing) and Type F (high-range water-reducing) admixtures, ensuring compliance with industry regulations.
