Concrete Mix Floor Screed

A floor screed is usually a cementitious material made from a 1 3 or 1 4 5 ratio of cement to sharp sand.

Concrete mix floor screed. 3 5sand 0 4mm washed sharp sand for levelling screeds. Concrete has the potential to hit a very high compressive strength which makes it an ideal building material. It is used in everything from walls driveways patios and roads to piling concrete floors and other building structures. Mix ratio of sand and cement screed for floor varies based on the intended use of the screed.

Added to that cement type grade of aggregate and the method of storage of screed material influence the mix ratio to a certain extent. It may be applied onto either a solid in situ concrete ground floor slab or onto a precast concrete floor unit. Screed however is a smoother mix which consists of considerably less aggregates to that of the mix used for concrete. The benefits of concrete and screed.

Screeds generally follow a mix proportion of 1cement. There are many proprietary screeds on the market and information about these can be obtained from the manufacturer. Screed on the other hand is a thin layer of cement paste and sand fine aggregates laid on to a concrete floor base or underfloor heating to act as a smooth flat levelling surface for taking on the final floor finish. 1 tonne of flooring grit or sharp sand mixed at 4 sand to 1 cement will cover approximately 15 square metres of floor when laid at 40mm thick.
