It was shown earlier that aggregate types do not materially affect the performance of water-reducing admixtures. This is not true for cement and mixes containing special cements require particular care. Examples here are increased retardation with low C3A cement (for example, sulfate-resistant cement) and... [Pg.80]

Some carbonation tests have been reported on plain and air-entrained concretes using two aggregate types, where the depth of carbonation on indoor and atmospheric exposure for 5 years have been measured [40]. The results are given in Table 3.24. In all cases, the air-entrained mixes have shown less carbonation than similar controls, suggesting that air-entrained concrete should provide a better reinforcement protection in the long term. [Pg.220]

Aggregate type influences expansion and shrinkage characteristics of concrete. Use of aggregates of high elastic modulus results in larger expansion [80]. [Pg.343]

The effects of some admixtures are significantly modified by such factors as water content and cement content of the mixture, by aggregate type and grading, and by type and length of mixing. [Pg.517]

The properties of an overall concrete system in the plastic state will be a function of many parameters such as aggregate types and shapes, cement contents and characteristics, etc., but it is useful to isolate the effect of the paste rheology where it can be stated that ... [Pg.29]
