Irritation is caused by the skin's exposure to concrete and, more specifically, its aggregate material makeup. This is because concrete includes a binder ingredient called Portland cement, which is also found in mortar, plaster, grout, and more. When wet, uncured Portland cement reaches caustic pH levels of 12 or higher, compared to the skin ...unconfined flow of the concrete is measured with this test. L-Box Measures the concrete flow from the vertical part of an L-shaped box to the horizontal part. Determines the ratio of the concrete height at the end of the box vs. the height of the concrete at the front of the box after the test is performed.

Water/cement ratio theory states that for a given combination of materials and as long as workable consistency is obtained, the strength of concrete at a given age depends on the w/c ratio. The lower the w/c ratio, the higher the concrete strength. All materials used for a design including the water quality should be to a high standard.4 ÷ 12 = .33. 100 x .33 = 33 cubic feet. 33 x .037 = 1.22 cubic yards. Essentially you are solving for volume and then converting to cubic yards. For concrete, the formula for volume is as follows: length x width x thickness. To determine how many bags of concrete you will need, divide the total cubic yards needed by the yield.
