StrataForge Mix Designer
Design a concrete mix and see how strong it should be, how sure the model is, and how it compares with real trials. Move a slider and the prediction follows.
Set the mix or load a real trial, then predict its strength.
Waking the model
The demo sleeps when nobody is using it. Your mix is queued and runs as soon as the machine is up.

Your mix is kept. Retry now, or read the model card while the service recovers.
GET /healthStrength climbs fast in the first month and slowly after that, which is why the model uses the log of age. Beyond 100 days the line is an extrapolation, because no fitted trial was tested later.
Closest trials to your mix
Every row is a real mix from the 651 fitted trials. Compare what the lab measured with what the model predicts for that same mix.
Predict a mix first. Its ten closest trials appear here.
Five terms, one straight line
A multiple linear regression built in R by forward stepwise selection. Age and superplasticizer are logged, because both are heavily skewed. The API serves the six coefficients and their covariance matrix, so every interval is exact.
