About Concrete Mix Ratio Calculator
MIXES IT COVERS
Indian grades M5 to M25. UK and European C classes. All-in ballast at 1:4, 1:5 and 1:6. US ratios like 1:2:3. Concrete Society job proportions, or type your own. Mortar 1:3 to 1:8 for bricklaying, bedding and pointing. Plaster and render by wall area and coat thickness. Metric and imperial, MPa or psi.
YOUR BAG AND YOUR MIXER
Search the sack rather than the mix: seventeen branded cements from six UK and US makers, plus premix and plain cement in the usual sizes. Batch in a mixer, barrow, bucket or gauge box, counted in buckets, litres, cubic feet or shovels. Mixer capacity uses drum volume or load rating, whichever runs out first, and you can add your own machine off its plate. Damp sand corrects the sand and the water together.
WATER, AND THE WORKING BEHIND IT
Water per bag comes off the manufacturer data sheets. For site mixes it comes from the water/cement ratio, capped at the code maximum for your grade. Every result opens into the arithmetic: dry volume, the split per ingredient, how the bag count was reached, and the document each figure came from. Reference tables and a mixing timer are included.
OFFLINE, AND FREE
No account, no cloud, no analytics. The app does not ask for the internet permission at all. It is free, with no ads, no subscriptions and no in-app purchases. One donation link in Settings. Share the plan as text or save it as a PDF, both made on the phone. TalkBack and system text size are supported throughout.
WHAT IT IS NOT
This batches nominal mixes. It is not a design-mix tool, and grades above M20 are labelled as needing one. Quantities are estimates: bulking, moisture, wastage and drum fill all move them. Check anything structural against your own specification.
