Aug 11, 2018 Coarse aggregates are particulates that are greater than 9.5mm. The usual range employed is between 9.5mm and 37.5mm 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

Floor screeds

Floor Screeds

Floor screeds. A floor screed is usually a cementitious material made from a 13 or 14.5 ratio of cement to sharp sand. It may be applied onto either a solid in-situ concrete ground floor slab or onto a precast concrete floor unit. There are many proprietary screeds on the market and information about these can be obtained from the manufacturer.

Gradation The importance of the granulometric curves in

Gradation The Importance Of The Granulometric Curves In

Gradation directly affects both quality and costs of concrete, because to bind aggregates into one solid unit demands that each particle be completely coated by the cementing paste and, in addition, that paste fill all space between the particles. Excessive space hinders making a mix uniform, and requires additional paste to fill useless voids.
