Fly Ash Cement B-V 32.5

Fly Ash Cement is produced by milling clinker, fly ash (max 10-30% by weight) and a given amount of gypsum. It hasn’t got any sub classes. Its early strength value is UKC 32.5 within 28 days. It is referred to as CEM II B-V.

Slugged Cement B-S 42.5-R

Portlad Slug Cement is produced by milling clinker, slug and a given amount of gypsum. They are classified into two according to the amount of slug in them. Type A includes %56-20 slug by weight and type B includes 21-35% slug by weight. They are classified into six types according to their early strength periods within 28 days: PCC 32.5, PCC 32.5R, PCC 42.5, PCC 42.5R, PCC 52.5, PCC 52.5R. This cement type is newly adopted from European standards.
Produced in compliance with TS EN 197-1 standards.

Areas of use include all kinds of concrete and high buildings, ground concretes, prefabricated concrete components, bridges, viaducts, water stores, concrete brickets, industrial work grounds contaminated with medium level sulfate, concrete sewage pipes, general-purpose construction works where a low hydration temperature is needed.

Trass Cement B-P 32.5-R

A hydraulic cement produced by milling 80-60 parts (by weight) of Portland cement clinker together with a corresponding amount (20-40 parts) of trass (TS 25) and a quantity of gypsum.

It conforms to TS 26.

It is used in dams, foundation concretes, and tunnel construction works as it is highly resistant to alkali, salt, and aggressive water; in block concrete construction works where the hydration temperature must be rapid; in the construction of agricultural and industrial facilities.
