Miksir is an AI assistant trained on ACI, EN 206, TS 500 and more — giving civil engineers code-compliant mix designs through natural conversation.
The Problem
Civil engineers spend hours navigating complex code tables, running manual calculations, and second-guessing compliance.
Engineers manually reference ACI tables, perform iterative w/c calculations, and verify results — a process that takes 2-4 hours per design.
Different projects demand different codes. Switching between ACI 211, EN 206, and TS 500 is disorienting and risks non-compliance errors.
Spreadsheets get lost. Calculations aren't reproducible. Handing off projects to colleagues means starting from scratch.
The Solution
Just describe your project — Miksir handles the code lookup, parameter selection, and compliance checking automatically.
Describe your project in plain language. Miksir asks clarifying questions and guides you to an optimized design naturally.
Every design is automatically validated against the selected code standard. Get a full compliance checklist with every result.
All designs are saved to your account. Export any design as a professional PDF report for submittals and documentation.
Features
Automatically identifies the correct exposure class from project description and maps it to code-mandated requirements.
Recommends optimal aggregate grading, water reducers, and SCM percentages for your strength and workability targets.
Generates batch quantities for any volume, from lab trial batches to full truck loads, with printable batch tickets.
Set your preferred code standard in settings, or switch per-project. ACI 211, EN 206, BS 8500, TS 500 all supported.
Ask Miksir to adjust strength, reduce cost, or modify workability. It recalculates instantly while maintaining compliance.
All designs encrypted and stored. Access from any device. Share with colleagues or clients via a secure link.
