To cast 41 cubic yards of concrete, you typically use a mix ratio of 1 part cement, 2 parts sand, and 3 parts gravel (aggregate). For 41 yards of concrete, you'll need approximately 6.8 cubic yards of cement, 13.6 cubic yards of sand, and 20.4 cubic yards of gravel. Adjust the mix based on specific project requirements or concrete strength needed. Always consider adding water based on the moisture content of the materials and desired workability.
Pcc = portland cement concrete or pre cast concrete
Concrete is stronger than cement.It is composed of aggregates (sand and gravel) and cement; and may be cast with reinforcing bar within it (reinforced concrete). Cement is only a part of concrete. Cement has no tensile strength while concrete has compressive and tensile strength.

The initial setting time of cement is 30 minutesThe final setting time of the cement is 10 hours.The initial and final setting time of the cement can be found by using the Vicat's apparatus.
Curing is necessary for freshly cast concrete in order to maintain the moisture as the chemical constituents in cement react with water and heat evolves continuously until the setting process completes. The heat evolved during the setting of concrete is called heat of hydration, and this heat causes the water to evaporate. Proper and complete setting process is the most important phenomenon that imparts the desired strength to the concrete. If the freshly cast concrete is not cured, it develops cracks and also the chemical reactions will cease resulting in bad concrete.
Concrete Is made out Of Clay..Dry Cast Stone..Is made Out Of Stone.. ;D

A thin coat of fine cement that is applied to the exterior of cast concrete that smoothes out the voids and imperfections and evens out the finish and color.

Cast stone, also known as a refined architectural concrete building unit is manufactured to simulate natural cut stone. These stones are used in unit masonry applications./
becos precast girders are not cast in -site and therefore faster. they also available in standard size.
The initial setting time of cement is 30 minutesThe final setting time of the cement is 10 hours.The initial and final setting time of the cement can be found by using the Vicat's apparatus.

What are Advantage pre cast concrete slab than insitu concrete?
Concrete Pump is an equipment mounted on a Truck Chasis, which does the job of Mixing the cement Mortar and delivering the same at work site as ready Mix concrete. Since the mortar mix can directly be poured or pumped to cast the slab or column or any other structural component, it is termed as Concrete Pump please visit the URL : - http://www.concretepumps.com for further reference.
