Sensor-Based Method Revolutionizes Concrete Sedimentation Testing
New sensor-supported method for rapid and user-friendly testing of fresh concrete sedimentation stability, developed at IWB Stuttgart by Franz Ludwig GmbH, addresses challenges with modern concretes Challenges with Modern Concretes Modern concretes are becoming increasingly complex to meet current demands like slender structures and filigree components. The use of highly effective superplasticizers makes these concretes not only more performant but also more susceptible to environmental factors and segregation. Maintaining the desired fresh and hardened concrete properties is becoming increasingly problematic. To date, quick and user-friendly methods for on-site testing of concrete sedimentation stability are lacking. Therefore, it is crucial to examine these concretes for their tendency to segregate before placement. Developing a Novel Testing Method At the Institute for Construction Materials (IWB) at the University of Stuttgart, a sensor-based testing method is being developed to specifically examine soft concretes for sedimentation stability. Initial preliminary tests have already successfully confirmed the basic principle of the testing. The testing device,

The importance of moisture measurement and control when milling flour  The moisture content of grain is crucial for the milling process. This article describes how moisture content can be controlled to achieve benefits in terms of quality, environmental sustainability and profitability of the final product.
The importance of moisture measurement and control when milling flour
The moisture content of grain is crucial for the milling process. This article describes how moisture content can be controlled to achieve benefits in terms of quality, environmental sustainability and profitability of the final product. Introduction Grain is a natural product, so the moisture in the bulk material varies due to several factors, including different growing conditions, weather conditions during harvest, the threshing operation, and post-harvest storage conditions. After harvest, industrially processed grain is often handled in a mill where it is flaked, rolled or ground into flour. Moisture levels are a critical factor throughout the mill because they affect machinery performance, material plasticity or malleability, and final product quality. Also, achieving the correct moisture content of the final product is important to prevent premature spoilage and a short shelf life. By measuring and controlling the water content of the material at each step of the milling process, it is possible to improve efficiency, reduce energy consumption, and save money. Consistent moisture control also enables a miller to achieve higher yields of better quality with less waste. The main process measurement

Impact of water-cement ratio on concrete brightness The water-cement ratio is crucial for concrete surface brightness. Moisture variations in aggregates and mixing processes affect the color and brightness stability of bulk material concrete.
Impact of water-cement ratio on concrete brightness
The water-cement ratio is crucial for concrete surface brightness. Moisture variations in aggregates and mixing processes affect the color and brightness stability of bulk material concrete. The Role of Water-Cement Ratio in Concrete Brightness Differences in the water-cement ratio (w/c value) are the most frequent cause of color and brightness variations in concrete products. Efflorescence also contributes. Modern cements and additives may introduce additional influences. Pigments do not change their properties during concrete production and remain permanently bound to the binder. However, the binder itself changes its chemical structure through hydration, which affects concrete strength. The formation of fine structures leads to brightness, as seen in efflorescence. The higher the w/c value, the brighter the concrete surface. Influence of Moisture and Temperature on Surface Brightness In fresh concrete, water acts as a reactant for the hydration of the binder. Concrete does not simply dry out; rather, the water chemically reacts with hydraulic cement and additives. Higher temperatures lead to brighter concrete surfaces. The amount of water remaining

Moisture Control in Animal Feed Production
One of the big challenges in the animal feed industry is the large number of different formulations. Controlling and measuring the moisture enables the correct calibration for each of the different formulations. One of the big challenges in the animal feed industry is the number of different formulations that can be produced by a single plant. For each batch, it is essential to ensure that the quality of the product is correct so that the animals are fed a balanced nutritional diet optimised for their type and stage of development. For this reason, moisture sensors are often used in conjunction with a control system that manages the formulation parameters. Controlling and measuring the moisture enables the correct calibration for each of the different formulations. Moisture control is a key factor in ensuring the final feed is palatable, retains its nutrients, and is consistent. Benefits of Moisture Control * Improve nutritional consistency * Reduce spoilage and waste * Improve shelf life * Optimise pellet durability * Increase plant efficiency * Reduce process downtime Where to Measure Moisture Effective moisture control of the entire process requires the

Moisture and Temperature Measurement for Sustainable Concrete New sensor technology enables precise moisture and temperature measurement in bulk materials for sustainable concrete production, optimizing processes and reducing CO2 emissions.
Moisture and Temperature Measurement for Sustainable Concrete
New sensor technology enables precise moisture and temperature measurement in bulk materials for sustainable concrete production, optimizing processes and reducing CO2 emissions. Eco-friendly thanks to precise sensor technology Concrete production faces the challenge of conserving natural resources and reducing CO2 emissions. One approach is the use of limestone powder or calcined clays as clinker substitutes. To efficiently process these new cements and additives and produce precisely differentiated concrete mixtures, adapted sensor technology is required. This technology records moisture and temperature at various points in the process chain. Particularly, the moisture content and temperature of individual raw materials such as cement, additives, and aggregates significantly influence concrete quality and must therefore be precisely monitored. Microwave moisture sensors for ingredients of concrete Moisture measurement is based on the dielectric method in the microwave range. The microwave moisture sensor is in direct contact with the measurement medium and penetrates at least 50 mm deep into the material. This allows for the detection

What else can be measured with NIR moisture sensors?
Moisture sensors determine the moisture content, but there are other parameters that can be measured with near infrared light (NIR). The name MoistTech is self-explanatory that the moisture sensors detect moisture content, but there are so many more substances that absorb near infrared (NIR) light. Coating weight, protein and temperature are just a few measurables that can be detected with MoistTech’s line of products for quality control. How does NIR work? NIR technology works when different substances absorb NIR light at specific wavelengths. After analyzing the amount of NIR light absorbed in a sample, the machine can provide in-depth information about the substance being measured. In the case of MoistTech, it is a popular tool for industries that need to control moisture content in products, such as paper and food production. What does NIR measure? Moisture is far from the only entity NIR can measure. It can also detect levels of coating weight, sheet and film thickness, oil, protein and temperature, among others. NIR technology can be used in many industries including food, agriculture,
