In a previous blog post on material blending we touched on some of the reasons why a user might want to employ material constraints while blending multiple aggregate products. I would like to expand on those reasons and add a few more to the list. The mathematical and visual blending tools available in StonemontQC for aggregate,
Introduction Concrete batching/dispatching and quality control/mix design software have a mutually beneficial need to communicate with each other. Currently, no universal application programming interface (API) exists for this purpose other than the ULINK protocol, which is seriously outdated and limited. ULINK uses the BYSYNC protocol that was developed by IBM almost 50 years ago
Introduction Blending material gradations to obtain consistent characteristics and performance can be a tremendous challenge, especially when faced with sources that can change over time. Without tools to show you both mathematically and graphically what is happening, means that any adjustments to the blend are like a shot in the dark. Not only can
Temperature Time Factor (TTF) calculations and compressive strength results are used for estimating concrete strength gain using the maturity method as outlined in ASTM C 1074. To develop the data used for this type of evaluation, cylinders are cast to be broken at certain intervals. The total curing time in either days or hours and
Introduction In previous blogs we have discussed the benefits of the Stonemont KPI and the Mix Risk analysis tool. Mix Risk uses the Stonemont KPI to provide an evaluation of potential future performance of a mix design prior to or during production of the mix. However, the Stonemont KPI also can be used to
Introduction The previous blog post, The Stonemont Quality KPI, focused on explaining the Stonemont KPI and the potential use of this value as a measurement of risk associated with aggregate products, asphalt mixes, and concrete mixes. In this blog post, we will show an example of using the KPI and the associated statistical measurements for
What is KPI? KPI stands for Key Performance Indicator, which is a type of performance measurement commonly used by an organization to evaluate its success of a particular function or activity. It is common for a company to have several performance measurements or KPIs. It is important that a company balance KPIs across several processes
Pervious concrete mixes are paving mixes designed to have enough interconnected voids so that water can easily penetrate through the concrete and into the subgrade where it can be absorbed into the soil. Property that was once used for managing storm water runoff can potentially be reduced, leaving more useable land for other purposes. Rather than
Most concrete producers have hundreds of mix designs to choose from. They cover a multitude of design characteristics to meet the needs of their customers. Despite this wealth of variation in mix designs, project specifications can prescribe a mix that doesn’t match anything that is already at the plant. It is often common practice to
Aggregate plant flow modeling in North America relies heavily on the use of crusher manufacturer provided gradations. These gradation estimates may provide a useful starting point when no other data are available. At existing plants, sporadic measurements of crusher feed and discharge gradations may be available. These gradations may represent different plant processes or modes
