Cements For Concrete Pavements Mixed Cement Or Type V with Fly Ash

Paper by HERRERO from ISCR 6th 1990

In Spain the development of cement, specially for concrete pavements, has been based on making use of fly ash in cement production. Such a development was achieved after studying the characteristics of the available fly ash and the respective experiencies. The results led to a widespread use of this type of cement in paving works with concrete, and it is included in the present standards. According to such standards, this cement is de-signated as Mixed or Type V cement. Concerningits composition, the clinker quantity must be bet-ween 20 and 64%; so fly ash proportion must bebetween 36 and 800/0.
