(PDF) Design of Reinforced Concrete Structures ...
This is the first Chapter of the Book released by Oxford University Press, New Delhi, recently. Design of Reinforced Concrete Structures is designed to meet the requirements of undergraduate students of civil and structural engineering. This book
Volume is volume. Because of the amount of concrete needed for most jobs it is usually easiest to figure the volume in cubic feet. If your project is large enough to calculate the volume in cubic yards instead of feet, call a ready mix concrete truck. When you hear "cubic" think ice cube.
Feb 26, 2018· An 80-pound bag yields approximately 0.60 cubic feet of concrete. 60-pound bags yield 0.45 cubic feet and 40-pound bags just 0.30 cubic feet. The actual yield is approximate because the amount of water added to the mix may vary. 60 to 80 pounds is a lot of weight to lift, carry and handle.

Nov 23, 2020· An example calculation. So let''s say we have 4 concrete elements, each 3 feet long, 3 feet wide and 3 feet high. Now we multiply 4 times (3*3*3).Pre-mixed concrete is usually sold by the cubic yard, and this unit is used by default.As construction elements are usually measured in feet, our calculator converts the volume into cubic yards - in our example 4 cu yd (108 cubic feet).
May 08, 2010· Since fly ash particles are spherical and in the same size range as portland cement, a reduction in the amount of water needed for mixing and placing concrete can be obtained. In precast concrete, this can be translated into better workability, resulting in sharp and distinctive corners and edges with a better surface appearance.
Nov 23, 2020· Our sand calculator can help you with that - all you have to do is enter the price of sand (per unit of mass, such as tonne, or per unit of volume, such as cubic yard). The calculator will then display the total cost of the sand you need.

needed to relieve this condition is to reduce the amount of sand in the mix. A reduction of 60 to 120 kg of sand per cubic meter of concrete (100 to 200 lb/yd3) may be enough. (Replace the sand removed by adding a like amount of the smallest size coarse aggregate available.) The slightly harsher mix should
