In addition if the Coarse aggregate : Fine aggregate = 60 : 40 then Coarse aggregate = 60/100 * 100 y/x Kg = 60 y/x Kg. Fine aggregate = 40/100 * 100 y/x Kg = 40 y/x Kg. Now Instead of a 50 Kg batch lets take cement weight = a Kg. We generally consider the total weight of concrete as 2400 Kgs per cubic metre. Meaning Wt. of Cement +Wt. of ...

seeding is fine as the aggregate will increase the thickness at the surface. The concrete is then smoothed with wood Darby's and bull floats. Wood is the recommended choice for the initial finish. NOTE: the larger the aggregate size in the seeding method the deeper the concrete level should be below the form. The forms should be set so that the final slab will be both drained well and level....

Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases soil-cement and in new concrete. After harvesting aggregate is processed: crushed screened and washed to obtain proper cleanliness and gradation. If necessary a benefaction process such as jigging or heavy media separation can be used to upgrade the quality. Once processed the aggregates are handled and stored to minimize segregation and degradation and prevent contamination....

Most stockpiled coarse aggregate is in the AD state with an absorption of less than one percent but most fine aggregate is often in the wet state with surface moisture up to five percent. This surface moisture on the fine aggregate creates a thick film over the surface of the particles pushing them apart and increasing the apparent volume. This is commonly known as bulking and can cause significant errors in proportioning volume....

The optimum ratio depends upon the shape and gradation of both the fine and coarse aggregates and the fiber type and content. When fibers are present the aggregate packing is modified which leads to a different optimum coarse/total aggregate ratio and void content. These curves were obtained with standard concrete sand and a 10 mm (0.394 in.) maximum size crushed granite coarse aggregate....
