Method for converting a first type of concrete reinforcing material to an equivalent quantity of concrete reinforcing fibers for designing a reinforced concrete slab. Fibers may be steel or other materials. User determines whether a slab to be reinforced is a lightly reinforced slab; and then uses...

The requirements for the database are to ensure that, in addition to the quantity and quality of the dataset, there are no significant linear relationships between the feature parameters. When the linear relationship between the feature parameters is strong, it will affect the model prediction accur...
Although PC has been used for over 30 years, the material is attracting renewed interests recently. It is attributable to the Federal Water Pollution Control Act [12] and the Environmental Protection Agency (EPA) storm water regulations [13] that require control of both the quantity and qualit...
Calculation of the quantity (X) of coarse aggregate (saturated surface dry) in 1 m3 of concrete: $${\text{Aggregate}}\,{\text{volume}}\, = \,1000 - 146 - 210 - 15 - 2 - 1\, = \,626\,{\text{ L}}/{\text{m}}^{3} .$$ $$\left( {X/2.68\,{\text{kg}}/{\text{L...
After measuring the relevant physical quantity, the equivalent age of the concrete can be calculated in accordance with the standard relation curve, which is obtained under standardized curing conditions. Indirect testing methods include the pull-out test12,13,14,15, rebound16, ultrasonic17, ...
The quantity and arrangement of the reinforcing steel. Small-diameter bars at close spacing reduce crack widths. • Prestressing of the elements will add a compressive stress to the elements and reduce the potential to crack, but that may not be practical or economical. • The type of formw...
