Ultra-High Performance Concrete (UHPC) Additives

What is Ultra-High Performance Concrete?

Ultra-High Performance Concrete (UHPC) is a new class of concrete that has been developed in recent decades for its exceptional properties of strength and durability. This high-performance concrete can be utilized in structural rehabilitation and accelerated bridge construction in addition to several other applications.

Adding corresponding functional chemical additives, Ultra-High Performance Concrete can perform exceptional strength, flexibility, durability, and longevity, making its quality far exceed that of the ordinary concrete used today in all aspects. As a world-famous manufacturer of specialty chemicals, LANDU provides our biodegradable chemical additives to strengthen your UHPC performance while ensuring its good durability and eco-friendly properties without generating pollution to humans and the environment.

What are Additives in the Ultra-High Performance Concrete Formula？

Ultra-High Performance Concrete is composed of Portland cement, silica fume, quartz flour, fine silica sand, water, and additives. Common additives are water reducers, defoamers, and more. As a global leading specialty chemical manufacturer, LANDU is dedicated to manufacturing high-quality chemical additives and providing the best UHPC solution for your specific demands and application situations.

LANDU Additives - Make Your UHPC More Powerful

LANDU NOVASTAR is a core brand of LANDU, which reflects Landu’s ultimate pursuit of product innovation.

Novastar additives for Ultra-High Performance Concrete include NOVASTAR Polycarboxylate Superplasticizer, NOVASTAR Powder Defoamer, and more. They can significantly improve concrete flowability without increasing the water content, allowing for high-strength concrete with lower water-to-cement ratios. Also, it can accelerate the early strength development of concrete without disrupting reactions among other components.

Core Additives in Ultra-High Performance Concrete

Поликарбоксилатен суперпластификатор

Polycarboxylate Superplasticizer (PCE), also known as a water reducer, is an innovative and advanced chemical additive used in concrete. NOVASTAR PCE powder and PCE flakes have been used in many factories worldwide. When a certain amount of polycarboxylate superplasticizer is applied to high-performance concrete, it has the advantages of a small dosage and a high water reduction rate, which can ensure that the concrete has good fluidity. Meanwhile, it has a good effect on improving the strength of the concrete at different ages, which is not possessed by other water-reducing agents.

Предимства:

Enhance Workability: Its unique comb-like structure makes it effectively disperse cement particles and prevents the rapid formation of cement flocculation structures, thereby improving the workability and density of concrete.

Intensify Strength: It can significantly enhance the early strength of concrete, facilitating smooth concrete pumping and ensuring good performance.

Reduce Slump Loss: It can significantly reduce the slump of concrete, especially during the pre-mixing process, with the slump loss value controlled within 15%, which is convenient for the transportation and construction of concrete.

Improve Durability: Due to its low alkali content and sodium sulfate content, it helps reduce the alkali-aggregate reaction in reinforced concrete and improve the overall durability of concrete.

Strong Adaptability: With strong adaptability and good compatibility, it can adapt to different engineering requirements and environmental conditions by adjusting the dosage and mix ratio.

LANDU NOVASTAR powder defoamer plays an important role in UHPC to control the formation of bubbles and foams. Its main component is siloxane and is usually accompanied by the presence of organic groups, which endow silicone-based defoamers with hydrophilicity and lipophilicity, enabling them to effectively disperse bubbles in concrete and simultaneously improve the compactness and strength of the concrete.

Предимства:

Eliminating Bubbles: Defoamers can effectively reduce the bubbles, preventing phenomena such as honeycomb and pitted surfaces and improving the flatness and gloss of the surface.

Improving Mechanical Properties: It can reduce the bubble content in concrete and lower the air content, thereby enhancing the density and mechanical strength of the concrete.

Improving durability: By reducing bubbles, it can extend the service life of UHPC in harsh environments, by reducing the penetration of moisture and enhancing resistance to carbonization and chlorination.
