All concrete is not the same. In fact, builders use different ratios of materials to create concrete that is more durable or more flexible depending on the need of each project. When building, pounds per square inch (psi) is used to express the strength of concrete. A 3,000 psi concrete can withstand 3,000 pounds of pressure per square inch and qualifies as an extremely strong concrete. A 3,000 psi concrete can be properly mixed using basic mixing methods.
Things You'll Need
- 3,000 psi concrete mix
- Garden hose
Walk the wheelbarrow over to the site where you will be pouring your 3,000 psi concrete and set it down on a level surface.
Pour out the 3,000 psi concrete ready mix into the bucket of the wheelbarrow. If you are adding more than a bag of the concrete to bucket, make sure that both bags are the same brand and that both bags are listed as 3,000 psi concrete. Since manufacturers of concrete use slightly different ratios of materials, you don't want to throw off your mixture by mixing together two different brands.
Incorporate water into the powdered concrete in small quantities while stirring with a garden shovel or spade. Follow the directions on the concrete for the correct ratio of water to powdered concrete. Most 80 lb. bags of concrete mix require about 3 qts. of water. Once the concrete has the consistency of oatmeal, it is ready to be poured.
Tips & Warnings
- If you have more than four or five bags of concrete to mix, consider using an electric mixer. Mixing by hand is hard work.
