Company-driven improvements have led to improved equipment reliability, energy efficiency, and the increased the use of alternative fuels. In fact, alternative fuels, such as industrial byproducts that otherwise would end up in landfills, now represent more than 15 percent of total cement plant energy consumption in the U.S.
Hydronix sensors were originally designed for the ready-mix and pre-cast concrete industries to increase the accuracy of batching and slump control. However, microwave moisture measurement has also proved to be invaluable in other industries that use sand or aggregates during processing. Benefits. Reduction in number of spoilt batches

Measuring compaction To find out how well a soil has been compacted we must measure the dry unit weight or dry density in pounds per cubic foot. Dry density is a measure of the weight of solid material present in a cubic foot of soil. The higher the dry density, the stronger and less com-p r essible the soil will be. One method for determ i n i n g
This unique technology allows producers to better understand and optimize mixing time, batch sequencing, and mix design. The Quality Control (QC) and Production Managers now have air measurement records for every batch of concrete produced. The AIRtrac system improves concrete quality and consistency and reduces the cost of production.
This includes colours or additives such as water proof agents, shrinkage reducers etc. If you are unsure please contact one of our sales team for assistance, before ringing the plant. We supply what has been ordered and request that this information is clear to the order taker. How much concrete do I need and how long between loads.
the concrete floor. Of course we can offer especially coordinated equipment for the water supply and -drain. In order to construct prostheses and orthopaedic aids, proper devices and tools are of enormous importance! With our construction- and casting devices, you are laying the corner stone for excellent functional properties
While there are many types of cement, Portland cement is the most commonly used cement, and is an ingredient in concrete, mortar, and plasters. Concrete can be purchased in multiple forms, including in 60 or 80-pound bags, or delivered in large amounts by specialized concrete mixer trucks.

Place the plywood sheet on your work surface, propped up with scrap to allow clearance for the circular-saw blade. Following the cut list, measure and mark the dimensions for the sides, inset panels, base, and cleats of the concrete form. Use a circular saw and a rafter square, as shown, to make the cuts.

Concrete Strength: What is the Compressive Strength of Concrete? The strength of concrete is measure in terms of pounds per square inch (or PSI). PSI is a measure of compressive strength, or the ability of the material to carry loads and handle compression. 1.) 2500-3000 PSI Most concrete has a PSI rating of 2500 to 3000.
Editor’s Note: This is the first article in a year-long series that focuses in on the details and more technical aspects of one common thing precast concrete producers do on a daily basis. Ask among precasters, and you’ll hear all sorts of unique ways aggregate moisture content has been tested over the years.
