Compressive strength of concrete measure in different standard units, one of the most common is PSI, which is stand for Pound per square inches. The Compressive strength of concrete in PSI is a measurement of the concrete’s ability to carry loads or handle compression.

The higher the value of PSI, the stronger the concrete, low value of PSI weaker the concrete. Strength of concrete is the result of multiple factors involved, but is primarily the outcome of the concrete’s ingredients—the ratio of cement, sand, water and aggregate.

The common strength of concrete in PSI are 2500 PSI, 3000 PSI, 3500 PSI, 4000 PSI, 4500 PSI, 5000 PSI. These are used for many purpose: foundation, footing, slab casting, sidewalk, Patio, driveway and for general construction. One of the common comes in mind how many bag mix is a 3000 PSI concrete or how many PSI is a 7, 6, 5, 4, 8, and 9 bag mix?.

One bag or sac of Portland cement comes in 94 pound weight which yields about one cubic foot volume. As per old thumb rule increment of 1 bag or 94 pound of Portland cement in concrete mix will lead to increase about 900 PSI strength or 100 pound cement will increase 950 PSI.

One yard of concrete mix batch weighs about 3,600 pound. What is mix ratio of concrete?, General mix ratio is 1:2:3 (One part of cement to two parts of sand to 3 parts of gravel) used for construction. Mixing of 6.5 sac or bag of cement with 1:2:3 mix ratio yields 4000 PSI concrete.
