EFFECTS OF AGGREGATE TYPE, SIZE, AND CONTENT ON CONCRETE .increase in aggregate size results in a decrease in the compressive strength of concrete. Cook (1989) showed that, for compressive strengths in excess of 69 MPa (10,000 psi), smaller sized coarse aggregate produces higher strengths for a given watertocement ratio. In fact, it is generally agreed that, although larger coarse aggregates can be used

Properties of recycled aggregate concrete designed with ... · Concrete is a mixture of coarse aggregate, fine aggregate, cement and water (Fig. 1(a)).However, in the existing conventional mix design methods, when concrete is produced by replacing NA with RA partially or entirely, the total unit mortar in concrete rises, and the proportion of original coarse aggregate decreases due to the presence of the AM in the RA (Fig. 1(b)).

Aggregates for Concrete Fine aggregates are usually sand or crushed stone that are less than in diameter. • Typically the most common size of aggregate used in construction is 20mm. A larger size, 40mm, is more common in mass concrete. • Larger aggregate diameters reduce the quantity of cement and water needed. 20 mm aggregate . Common aggregates ...

Concrete Mix Design | Different Grades of Concrete · To make ease in understanding we are finding the Concrete mix design of M20 grade concrete. The Concrete mix ratio for M20 grade of concrete is 1::3 that mean 1 part of cement, part of sand (fine aggregate) and 3 parts of aggregate (crushed stone) in volume and then batched for mixing. To know the Concrete Mix Design follow below:
Size of aggregate used in RCC, PCC, slab, Road, Bridge ...Why 40mm size aggregate is preferred in PCC or mass concrete than 20mm: for the same strength or workability, concrete with large size aggregate will require lesser quantity of cement than concrete with a smaller size aggregate. In a mass concrete work or PCC the use of larger size aggregate will be useful due to the lesser consumption of cement, this will also reduce the heat of hydration ...

Aggregate size| Concrete Construction MagazineThe larger sizes will require less mixing water and hence, for a given cement factor, will produce concrete of lower waterratio than the smaller sizes. 3. The advantage of small aggregate in the waterratio strength relationship may or may not be sufficient to offset the effects of its higher mixing water demand. It appears that optimum maximum size, so far as strength is concerned, will vary ...
