A concrete mixture ratio of 1 part cement 3 parts sand and 3 parts aggregate will produce a concrete mix of approximately 3000 psi Mixing water with the cement sand and stone will form a paste that will bind the materials together until the mix hardens
WhatsApp
These materials impart additional strength to the concrete by reacting with portland cement hydration products to create additional CSH gel the part of the paste responsible for concrete strength It would be difficult to produce highstrength concrete mixtures without using chemical admixtures
WhatsApp
These strengths are gauged according to a PSI rating PSI stands for pounds per square inch and refers to how much weight the concrete can safely support For most construction jobs including driveways and sidewalks 4000 PSI should be used Although there is a 5000 PSI concrete product on the market 4000 has become the industry standard
WhatsApp
PSI is a measure of compressive strength or the ability of the material to carry loads and handle compression 1 PSI Most concrete has a PSI rating of 2500 to 3000 This type of concrete can be used for sidewalks and residential driveways
