In this context the consistence of the concrete is an important factor, since a very low consistence class may result in increased resistance to pumping. A target slump of 70 - 90 mm is generally considered to be about the right level and the addition of a plasticizing admixture avoids a higher free

Various types of aggregate undergo chemical reactions in concrete, leading to damaging expansive phenomena. The most common are those containing reactive silica, that can react (in the presence of water) with the alkalis in concrete (K 2 O and Na 2 O, coming principally from cement). Among the more reactive mineral components of some aggregates are opal, chalcedony, flint and strained quartz.

Properties of "Ordinary Portland Cement Concrete ...

Concrete made with Portland cement is widely used as a construction material because of its many favorable characteristics. One of the most important is a large strength-cost ratio in many applications. Another is that concrete, while plastic, may be cast in forms easily at ordinary temperatures to produce almost any desired shape.
