How can we help?

Why alcemy exists

There are several decisions you have to make in cement production. You need to balance the 2 day and 28 day compressive strength within a particular target corridor while dealing with varying clinker properties and inconsistent slag and fly ash qualities. All of your raw materials may even have different availabilities and prices.

We have built Control Theory algorithms and Machine Learning models to utilize all your available laboratory data to help you with these decisions. We combine your strength, that is your deep understanding of cement manufacturing, with the strength of algorithms, making inferences from big data.

Our system makes sure that you produce your cement right on target in the most cost efficient way.

How it works

1. Upload your Laboratory Management System data exports or use our integration services.

2. Get Machine Learning powered product quality forecasts for your cement mixtures.

3. Get suggestions for process optimizations.
