Abstract

There are several express methods for cement activity determination in terms of forecasting cement brand. They are widely used in construction industry in recent years. These methods are called contraction methods of real-time determination and cement activity forecasting. The methods based on activity interrelation with processes of cement material absolute volume reduction caused by cement hydration. In Russia, contractometers are used in laboratory practices. Besides automatic contraction measuring equipment is used since 2009. Express methods of cement activity determination are also regarded under construction technology laboratory conditions.

Key words:

Portland cement, cement paste, cement activity, contraction measuring equipment, reinforced concrete products, concrete strength
