Enter the volume of the pour and the proportions of your site mix, then type your own prices: the cement bag, the sand and the gravel per m³, the mixing labour, and for ready-mixed concrete the price per m³, the pump and the delivery. PRAXAO gives the bags to buy, the total and the cost per m³ of each option, and the difference between them. No price is built in: nothing appears until you have typed them. The example figures are illustrative, not market prices. The tool compares costs: it does not choose a concrete class or weigh quality, workability or delay.

Only those you type. None is built in or guessed, so the comparison reflects your own suppliers and your own site.
No. It compares costs. Quality, workability, the strength class, the delay and the equipment on site are for you and the engineer to weigh.
The cement per m³ times the volume, divided by the weight of a bag and rounded up to a whole bag.
Bags, sand, gravel, labour against price, pump and delivery: the method to compare two ways of supplying concrete.
