UHPC products is very precise proportion control of raw materials, temperature control and optimization of the mixer’s performance requirements. For the most efficient and consistent mixing of UHPC, high shear mixers (Figure 1) have been used successfully, especially counter-current pan mixers, which can provide accelerated mixing times.
In order to produce UHPC, the mixer can be equipped with a special agitator tool and a special drive with a speed of up to 400 rpm. As a result, the mixing time can be reduced to as low as approx. 2 minutes.

About 20 to 25 minutes were required to load the mix, mix the UHPC, and discharge the mixer. During discharge from the truck, cement balls were observed in …
This study presents an investigation on the mixing efficiency of Resonance Acoustic Mixing (RAM) Technology® using ultra-high performance concrete (UHPC). In the first part, RAM is optimized through acceleration curve profiles, specific mixing energy, and workability spread flow tests.
Ultra-High Performance Concrete (UHPC) is a new type of concrete that exhibits material characteristics far surpassing all other concrete types. To obtain UHPC’s superb properties, caution must be made to all aspects of its formation, including mixing. Typically, the specified mixer for UHPC is a high energy/high shear mixer.
UHPC is generally understood to be a concrete with compressive strength at least 20 ksi, post-cracking tensile strength at least 0.72 ksi, and a discontinuous pore …
Concrete is the most widely used material in building construction. Within the last few decades, research has been conducted on what is known as Ultra High Performance Concrete (UHPC). The term includes a broad range of materials such as defect-free, dense particle, engineered composite, multi-scale particle, and fiber-reinforced cementitious

The Growing Market for Ultra-High Performance Concrete (UHPC) in Restoring American Infrastructure The American Society of Civil Engineers (ASCE) produces a report card every four years grading the condition and performance of the American infrastructure.
UHPC may be mixed in any type of mixer with proper mixer adjustments and optimization but best performance is achieved in high shear mixers. Most precast plant mixers work fine.
Apr 22, 2016 · UHPC is very easy to mix, if the recipe uses the binder Nanodur Compound 5941 of Dyckerhoff GmbH. The video shows a UHPC-mix using a simple rotary drum mixer.
With the independent speed control of the two agitators, especially the inner agitator, liquid and earth-moist concrete can be produced by the cone mixer. It is ideally suited for special concrete such as UHPC and SCC, fibre concrete, lightweight concrete, heavy concrete, etc.
